The Buying Guide to High-Quality Drill Bits for Aluminum

If you want to get the best drill bit for aluminum, there are several factors that you need to consider. These aspects have an impact on the suitability of the bits in dealing with aluminum material.

We have analyzed these factors in detail for you.

I) Material

The main feature to look out for is the material used in the construction of the drill bit. It should be strong enough to meet the demands that aluminum metal has.

There are certain materials that you should look out for. The first is high-speed steel (HSS), which can withstand high RPMs while remaining intact. A drill bit made of HSS is likely to have the versatility of drilling into different materials such as wood, stainless steel, and plastic, with ease.

An upgrade to ordinary HSS is coated with a black oxide that gives it corrosion-resistance and increases durability. And there are titanium-coated HSS bits which are sturdier and give out less friction to maintain their sharpness for longer.

Cobalt is the other material to look out for, and its primary benefit is the ability to withstand very high temperatures. Such bits are quite hard and can bore through sturdier materials such as stainless steel.

II) Speed

High speed gives you better working efficiency as it enables you to get the work done faster. Also, faster drilling is key to delivering clean holes, just the way you want them.

III) Shape

Another essential thing to talk about is the bit shape. This includes a split point tip that would enable your drill to start working as soon as it comes into contact with the surface. Such a design offers more precision, plus there would be less switching of the bits since you no longer have to create a “center punch.”

IV) Ease of Installation

We all like saving time, so a drill bit that is easy to install would help you attain this goal. You may be lucky to get a product that comes with instructions that guide you through the installation process.

V) Universal Compatibility

It is also wise if you look for drill bits with universal compatibility. This is because you can use the bits on different power tools without making significant concessions on the quality of the performance that you get.

VI) Storage Case

A high-quality storage case would provide you with secure storage for your drill bits plus would help you to be more organized with your tools. Further, the box would make it easy for you to take the bits with you on the road.
