If you’ll be drilling a lot of holes, or need to drill through hard, abrasive metals like stainless steel or cast iron, spend a couple bucks more for black oxide or a cobalt steel drill bit for metal. These bits will bore more holes before becoming dull.

What is the best drill bit for cast iron?

The best drill bit to use for cast iron is a cobalt bit with a 135-degree point angle. The angle is sharper than that on a conventional bit, making drilling faster and more accurate. Cobalt bits are brass-colored. As an alternative, you can also use a gold-colored titanium nitride bit.

Can you drill and tap cast iron?

Threaded holes in cast iron machine tables are just the solution you need for holding jigs and fixtures. George Vondriska shows how to cut a threaded through or blind hole in cast iron with a center punch, drill, tap and die set, a little oil drill and an all important back and forth motion.

Why won’t my drill bit go through metal?

Regular drill bits are not designed to cut through metals. Therefore, they can easily wear away. So you need hard bits which can drill through metals without being damaged.

What is the best drill bit to go through metal?

Cobalt drill bits are the best drill bits for hard metals including stainless steel. If you are using a hand drill then a 5% (M35) drill bit will be most suitable and it will be less brittle than other drill bits. TTP HARD drill bits are 5% cobalt and are a high quality drill bit.

Are titanium drill bits good for metal?

Titanium bits are suitable for drilling iron, steel, aluminum, magnesium, and wood. Titanium bits are great for general purpose drilling in a production environment because they drill quickly.

Is cobalt or titanium drill bits better?

Cobalt drill bits are more expensive, but offer longer life, and are more resistant to heat than titanium drill bits. Cobalt drill bits are also tougher and can drill holes in the hardest metals.

Can you cut cast iron?

You can cut cast iron with a plasma cutter torch, but this is not the best method to use. If you need to cut cast iron, your best options are to use either a snap cutter or a tool with a diamond blade.

Which is better black oxide or titanium drill bits?

Even though both the drill bits are less prone to friction during drilling, the titanium variety can drill relatively faster. This is owing to the greater strength and toughness of the latter, which facilitates ultimate speed while they are being used on most materials.

Can you drill a hole in wrought iron?

Beginning to drill without assistance from clamps can make it difficult to produce a hole that is both straight and on-center. Removing wrought iron fixtures to clamp them to a drill press is the best option. If this isn’t possible, you can drill a small hole to serve as a guide for a larger hole.

What drill bit do I use for metal?

Cobalt drill bits are used for drilling hard metal and steel. They dissipate heat quickly and are highly resistant to abrasions, making them better for drilling into hard metals than black oxide- or titanium-coated drill bits.

Can I Drill Through Cast Iron?

Cast iron is a sturdy metal that’s used in all sorts of applications. If you need to attach something to it or you have to release pressure, you could be worried about breaking a drill bit. However, it’s not as challenging as you might think.

You can drill a hole through cast iron with any drill bit for metal. Cast iron is much more brittle than other metals and is easy to drill into. Start drilling slowly to prevent overheating and excess friction that can damage your drill bit.

Before we get into the guide of how you’re supposed to drill through cast iron properly, let’s check out what items you need.

What Do You Need For Drilling Cast Iron?

First and foremost you will need a drill. If you don’t own one go and check my article on top cordless drills.

You can use almost any drill bit to cut through cast iron, including the cheap ones that you find in the discount aisle.

Since cast iron doesn’t resist the twisting motion of a bit, you’ll be able to drill right through it. The only issue that you’ll be dealing with is the debris.

If you want to make the task even more manageable, reach for a black oxide drill bit. They’re durable, and you won’t have tons of metal shavings stuck in the cast iron when you’re done.

You can also try out a cobalt steel drill bit, which provides additional toughness. It’s nearly impossible to break a cobalt steel twist bit on cast iron.

Either of these substances will cut right through the metal without becoming dull too quickly.

You can even take it a step further by getting a drill bit that’s coated with titanium nitride to resist heat and friction. Even if the cast isn’t hot, the friction will build heat quickly. It’s believed that drill bits with a TiN coating last up to six times longer than the average bit.

It also goes without saying that you should wear safety gear. Pick out a pair of goggles that protect your eyes and ears, as well as your temples. Don’t forget to get a durable pair of work gloves as well. You should pick a pair made out of leather or canvas to prevent slippage and potential harm.

Finally, consider wearing long sleeve clothing. Denim jeans and a work jacket will be more than enough to keep yourself from getting hurt. Even if you’re a professional, safety always comes first.

Alright! Without further ado, let’s jump into the step-by-step guide below.

How to Drill Through Cast Iron

Before you begin drilling, you’ll need to prep all of your tools to cut through the material easily.

Start by applying lubricant to your drill bits before using them. If you’re only drilling one or two holes, you don’t need to worry about lubing them.

However, anything more than that calls for cutting fluid. You can get a small bottle at a good price on Amazon. If you are doing a lot of drilling into metal I recommend you to get the 1 Gallon bottle of cutting fluid. Cutting fluid not only saves your bits but also prevents metal shavings from flying.

Here’s a simple guide to get it all done relatively quickly:

Create a dimple or an indent wherever you intend to drill. It’s always a good idea to mark the location, so you don’t go off course, but the indent also helps to guide the drill bit. Use a center punch and a hammer to make your marks. Attach the correct drill bit to your drill. Always check the size of the hole and make sure that you’re using the corresponding bit. If you’re following the hole with a screw, you need to use a bit that’s slightly small than the screw. The difference will allow the screw to hold onto the leftover metal, creating a secure bond. Brace the cast iron in place if it’s a loose piece. If it’s connected to an immovable object, it’ll already be braced for you. Consider a table vice to hold both sides of the material rather than only one side. Holding the drill upright, begin to slowly pull the trigger and place it against the indent that you created. Don’t be afraid to start with a smaller bit if you’re worried about making a mistake. It’s always better to do it a few times rather than mess the whole thing up. Once you’ve made the hole successfully, hold the trigger down, and slowly pull the drill back and forth in it. This process will deburr the hole, which means that it removes the metal debris that was left behind. Wipe down the surface with a dry cloth, then use a wet cloth, and repeat once more with the dry cloth. Don’t forget to get the inside of the hole, even if it’s thin. Metal debris can cause harm, but it also prevents screws from achieving a secure bond.

That’s all there is to it!

Again, this material never puts up much of an issue. It’s malleable if you use the drill bits mentioned at the beginning of this section.

To finish off, let’s review a few tips to help you get the job done well.

Additional Tips and Advice

Safety is essential, but so is convenience. Fortunately, you can get the best of both worlds by following these suggestions. Give them a try and figure out what gives you the results that you’re searching for.

Feel free to use the extra cutting fluid as you’re drilling. When you’re using a drill bit regularly, it starts to warm up. Wipe away the debris and reapply oil if you’re using it for long periods of time.

When you’re using a drill bit regularly, it starts to warm up. Wipe away the debris and reapply oil if you’re using it for long periods of time. Start with a slow speed setting. More speed = more friction, which means more heat. Slower drilling allows you to go through cast iron without dulling out your bits or over-heating your drill. You should never exceed 3000 RPM, though less than 1000 RPM is doable.

More speed = more friction, which means more heat. Slower drilling allows you to go through cast iron without dulling out your bits or over-heating your drill. You should never exceed 3000 RPM, though less than 1000 RPM is doable. Step bits are handy if you’re trying to drill a large hole. If you use one, make sure that you don’t go too fast; Otherwise, you could bore a hole that’s far too big.

If you use one, make sure that you don’t go too fast; Otherwise, you could bore a hole that’s far too big. Keep an old rag nearby whenever you use a drill bit on any type of metal. You’ll have to wipe up the excess cutting fluid and the metal shavings. Wiping it on your pants or shirt (as many DIYers have done) can cause injuries from the sharp debris.

Always mark your surface with a permanent marker beforehand . This indicator will give you a clear vision of where you want to start, rather than leaving you to guess where you should drill.

. This indicator will give you a clear vision of where you want to start, rather than leaving you to guess where you should drill. Don’t forget to check the width of the material that you’re drilling into! If you go too far, you could damage anything behind it. Keep a ruler and a leveler in your tool kit at all times to prevent those issues.

If you go too far, you could damage anything behind it. Keep a ruler and a leveler in your tool kit at all times to prevent those issues. Finally, never drill into loose cast iron. Vices are an absolute necessity if it’s not attached to a surface already.

Conclusion

Drilling cast iron is easy. It is a brittle metal that doesn’t have much debris.

The aforementioned heat-resistance and toughness make this material a top contender for at-home projects, so use it and drill into it without worrying about it breaking.

Here are a few key takeaways from this post:

You can drill into cast iron by using any type of drill bit for metal.

Don’t forget to use cutting fluid if you’re drilling many holes.

Always use a clamp or vice when you’re drilling into any surface.

Wear safety goggles, gloves, and clothing.

Remember to mark the spot with a marker followed by a center punch and a hammer.

Start drilling slowly to prevent excess friction, heat, and dulling.

Cheers, tools owners!

12 Tips for Drilling Holes in Metal

Almost any general-purpose twist bit will do a decent job of drilling holes in metal. In fact, most drill bits for metal are manufactured to drill through a variety of materials, including wood and plastic. The least expensive twist bits are made of high-speed steel (HSS), and these basic bits are just fine for most metal-drilling tasks. If you’ll be drilling a lot of holes, or need to drill through hard, abrasive metals like stainless steel or cast iron, spend a couple bucks more for black oxide or a cobalt steel drill bit for metal. These bits will bore more holes before becoming dull. Some bits also have a special coating called titanium nitride (TiN), which manufacturers claim helps resist heat and friction better, making these bits last up to six times longer than standard high-speed steel bits.

How to Drill Into Cast Iron

Cast iron is brittle, but as far as metals go, it isn’t very hard — so drilling a hole into it isn’t as difficult as you might expect. Moreover, you don’t have to be overly choosy about your drill bit. Any bit intended for drilling through metal will drill through cast iron. The key is to take your time to avoid overheating the bit and wearing it out.

To Lubricate or Not to Lubricate

Although many machinists advise against lubricating when drilling through cast iron, they don’t completely agree on the issue. Cast iron has a high carbon content, and since carbon acts as a lubricant it’s often acceptable to drill iron without lubricant. Lubricant makes a mess and can prevent metal debris from falling away from the bit as you drill. On the other hand, a lubricant, such as oil or a water-based coolant, cools the drill bit and the metal and helps to prevent cracking or excessive bit wear. The bo**ttom Line is this:** If you’re drilling one or two holes, you can rely on the material itself to lubricate your bit, but if you’re drilling many holes, your bit will probably last longer if you apply a few drops of cutting oil or spray lubricant before you drill each one.

Video of the Day

Warning When tapping, it’s important for the castings to fall away, or they can lodge in the threads; don’t use oil, and rely on the lubricating ability of the carbon in the material.

Drill Bits

You don’t have to search far and wide for a bit to drill through cast iron, but not every bit is appropriate, either.

What Not to Use

The only drill bits you should not use to drill cast iron are those intended for wood or masonry only. Cast iron would completely destroy the the brad point and extra-wide flutes of a wood boring bit, and a masonry bit is designed to use with a hammer drill; it would take all day for the dull tip of a masonry bit to penetrate cast iron. Spade bits, Forstner bits and auger bits are similarly unsuitable for cast iron — and metal in general.

What to Use

The best drill bit to use for cast iron is a cobalt bit with a 135-degree point angle. The angle is sharper than that on a conventional bit, making drilling faster and more accurate. Cobalt bits are brass-colored. As an alternative, you can also use a gold-colored titanium nitride bit. In fact, any high speed steel bit intended for metal — including all-purpose bits — is suitable for cast iron. When using a drill press, you may find that a bit with a 118-degree point angle drills more smoothly and creates fewer shards.

Tapping — any tap appropriate for metal works on cast iron, but you might prefer to choose one made specifically for cast iron.

Drill Speed

The recommended maximum drilling speed for soft cast iron is 150 surface feet per minute (SFM). This value is related to drill revolutions per minute (RPM) by the formula:

Advertisement

RPM = SFM x 3.82/drill bit diameter

If you’re drilling a 1/2-inch hole, then, the maximum drill speed should be 1,146 rpm, which is about midrange on most portable drills. Reduce this speed by half for hard cast iron — and if you’re drilling outside in the winter, reduce it to 300 rpm.
