Drill bits come in a plethora of types and sizes for drilling holes in a variety of materials. Many drill bits can pierce through more than one type of material, but not all drill bits can be used on metal without heating up and snapping in half. The best drill bits for metal are often made of high-speed steel, cobalt, or carbide and in order to reduce friction, are sometimes finished with such coatings as black oxide or titanium.

BEST OVERALL: Hymnorq Jobber Twist Drill Bits Set

The tapered noses and twisted side grooves of the bits in this set quickly penetrate to drill a steady, self-centering hole in many hard metals, including iron. The bits also work well for drilling in softer metals, such as aluminum and copper. (But they are not suitable for drilling into the hardest metals, such as titanium and high-carbon steel.) Made from cobalt steel (and molybdenum, for added durability), the Hymnorq bits are friction- and heat-resistant. 15 bits are included; these range in size from 1/16-inch to 3/8-inch. All come within a handy plastic storage case.

This set of amoolo 1/8″ Titanium Drill Bits comes with 10 1/8-inch titanium-coated bits made from high-speed steel for drilling 1/8-inch holes in softer metals, such as aluminum, copper, and alloy. These drill bits won’t work on iron, stainless steel, and other hardened metals. The twisted side grooves help stabilize the bit during drilling and direct metal shavings up and out of the hole. Additional sets of 10 bits are available in other sizes, including 1/4-inch, 3/8-inch, and 3/16-inch bits. The bits come in a plastic case for easy storage.

The set includes 21 bits, ranging in size from 1/16-inch to 1/2-inch, and they come in a handy plastic storage case.
