Cobalt Steel Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications. 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.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Carbide Drill Bits with Coolant Holes

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. A titanium aluminum nitride (TiAlN) coating gives them additional wear and temperature resistance. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
Jobbers'-length drill bits have the rigidity and length required for most applications.

Short-Flute Extended-Length Carbide-Tipped Drill Bits

The short flutes provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. A split point keeps the bit centered without a pilot hole.

Chip-Clearing Round-Shank Masonry Drill Bits for Rotary-Only Drilling

A more controlled chip removal reduces heat buildup, making these bits good for use on brittle material such as block and brick. Instead of using a hammering action to break up masonry material, they drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications.

Drill Bits for Precise Holes in Wood

Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. The center guide point prevents the bit from wandering. Also known as brad-point bits.
High-speed steel drill bits are stronger and more wear resistant than steel drill bits.

Cobalt Steel Hole-Starting Drill Bits


The short flute and length keep these bits straight for accurate placement when starting holes that will be drilled deeper with a longer bit. Also known as spotting drill bits. Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.
Bits with a 90° point angle are for centering and chamfering holes that will be followed by a smaller drill bit size.
Bits with a 120° point angle are for starting a hole that will be followed by a drill bit with a point angle from 90° to 118°.
