How to Choose the Best Metal Drill Bit

If you’re want to expand your tool collection or take on a metalworking project, a good set of metal drill bits might be just what you’re looking for. If you’re not sure whether you need a few long metal drill bits or a kit with dozens of options, you’re in the right place. We researched some of the best products available and put together this buying guide to help you figure it out. First, let’s look at some key things to remember.

Best Metal Drill Bits

Pieces: There is a lot of variety here when it comes to how many bits are included. These kits range from having as few as 9 bits to as many as 100 and just about everywhere in between.

Best Metal Drill Bits

Material: The most popular materials are cobalt and titanium. We found a few solid options made of steel, too. Metal bits have to be really hard and able to handle a lot of heat. Only a few materials meet those criteria.

How to Choose the Best Metal Drill Bit

Sizes: We included a range from the smallest to the largest bits in each kit. Most include bits in increments of 1/64 or 1/32-inch in this range. The more bits there are, the more sizes you get.

Best Metal Drill Bits

Carrying Case: This is one product where a carrying case is extremely useful. They not only help you carry and store the bits, but they also provide an excellent way to stay organized so you can always find what you need.

Best Metal Drill Bits

Weight: Weight matters if you’re planning to carry these kits back and forth. None of them are particularly heavy but some could be inconvenient on the job. They range in weight from 2.4 oz to 3.5 pounds.

Product Intro Icon

Warranty: Most (but not all) of these products come with a lifetime warranty. Think about it, these bits are made to cut through the hardest and toughest metals. It only makes sense that they’d last a really long time.
