Short-Flute Cobalt Steel Drill Bits

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life. A split point keeps the bit centered without a pilot hole.

Reversible Drill Bits for Sheet Metal

When one end becomes worn, reverse the bit to use the other end. These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing. They can be used in both hand-held drilling and machine-tool applications. The split point keeps the bit centered without a pilot hole.

These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing. They can be used in both hand-held drilling and machine-tool applications. The split point keeps the bit centered without a pilot hole.

Carbide Drill Bits for Sheet Metal

Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing.

High-Speed Steel Multidiameter Drill Bits



Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Black-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits and black-oxide drill bits.

Multidiameter Drill Bit Sets

Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
