Any-Diameter Drill Bits
Place a washer (not included) with an ID of the desired hole size over the bit and it acts as a stop to prevent the bit from drilling a larger hole.
Style A do not require a pilot hole.
Style B require a 1 29/64” pilot hole to start drilling.

Carbide Hole-Starting Drill Bits
Harder, stronger, and more wear resistant than cobalt 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. 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.
Bits with a 90° point angle are for centering and chamfering holes that will be followed by a smaller drill bit size.

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.
Titanium-aluminum-nitride (TiAlN) coated drill bits resist wear and temperature better than uncoated drill bits, so they last longer and can drill at higher speeds.
Bits with a 90° point angle are for centering and chamfering holes that will be followed by a smaller drill bit size.

Carbide Drill/Mill End Mills
Made of solid carbide, these end mills are harder, stronger, and more wear resistant than cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. A 90° pointed tip allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. All are center cutting, allowing plunge cuts into a surface.
End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts. End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds.
Use uncoated end mills for general purpose milling and short production runs. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills. Titanium-nitride (TiN) coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. Titanium-aluminum-nitride (TiAlN) coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

Cobalt Steel Drill/Mill End Mills
Made of cobalt steel, these end mills have good heat and wear resistance, so they can run at high speeds in hard material. A 90° pointed tip allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. All are center cutting, allowing plunge cuts into a surface.
Use uncoated end mills for general purpose milling and short production runs. Use titanium-nitride (TiN) coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.

Drill/Mill End Mill Sets
These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
