Metal Drill Bit Buyer’s Guide

Construction materials

Metal drill bits like the Irwin HSS Tin Pro Drill Bit Set make light working of cutting through metals such as aluminium, mild steel and stainless steel. A range of technologies is used to make drill bits hard and durable enough for this process. These include titanium coatings and 5% cobalt alloys.

Cobalt drill bits like the Sealey AK4701 Drill Bit Set are great for cutting through harder metals. However, they are a little more brittle than other drill bits so they must be handled with greater care.

Usage

Metal drill bits can be used on a range of metals including steel, stainless steel, hard metal, cast iron, hard alloys.

Most metal drill bits can be used with any standard drill. They are suitable for use with rotary and hammer drills. However, if you are using an SDS drill, you will need specialised SDS bits – these have a slotted shank.

When using cobalt bits, keep your speed low, ideally below 350 rpm and use a cutting fluid when cutting hard metals. This will keep the bit as cool as possible and reduce the likelihood of damage. You may also want to drill a pilot hole to make the process easier.

Some drill bits have the size stamped above the shaft to help ensure you are using the right size bit.

Cases

Most drill bit sets come in a case so you can store them safely and easily find the bit you need. The case can be either metal or plastic. Metal cases like that of the S&R Metal Drill Bits are more durable.

Safety

You should wear safety glasses, ear defenders, gloves and a mask when drilling metal.

Conclusion

It is essential to buy good quality metal drill bits if you want to drill through metal. Trying to use any other kind of bit will just waste your time and money. Bear in mind that a drill bit must be harder than the material it is working with to be effective.

We would recommend the DeWalt Extreme 2 Metal Drill Bit Set because it offers an extensive range of sizes and the durable bits come in a nice sturdy case.
