Also known as subland drill bits.High-Speed Steel—Wear and heat resistant, these bits are versatile for use on a range of materials.Oversized Tolerance—Often used when screw holes in sheets or layers are misaligned, these bits cut a slightly oversized hole.Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.Uncoated—Polished to eject chips, these are also known as bright finish bits. The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
