Multidiameter High-Speed Steel Step Drill Bits


Style A Round Shank 3-Flat Shank	Standard

With no fixed diameters, one bit cuts holes of almost any size within a range. Slip a washer (not included) over the bit to set your diameter. The washer acts as stop while drilling, so choose a washer with an inner diameter that matches your desired hole size. Wear and heat resistant, these high-speed steel bits are versatile for use on a range of materials.

Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.

Hole-Starting Carbide Drill Bits


Short Length Round Shank	Standard

Harder and more wear resistant than cobalt steel, these carbide bits create an accurate starting place in your workpiece. Cut an indent, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Carbide stays sharp at high temperatures and faster speeds. It can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

Short Length—The most rigid bits for drilling the straightest holes.

Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.

Titanium Aluminum Nitride (TiAlN) Coated—No drill bits last longer. These are the best for high-speed, high-temperature drilling of very hard and abrasive materials, including titanium and fiberglass.

Uncoated—Excellent for a range of materials but won't last as long as coated bits.

Hole-Starting Cobalt Steel Drill Bits


120° Point Angle	Standard

Create an accurate starting place in your workpiece. Cut an indent with these bits, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Cobalt steel resists wear to stay sharp when cutting hard materials, such as nickel. Also known as spotting drill bits.

Short Length—The most rigid bits for drilling the straightest holes.

Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron, titanium, and fiberglass.

Uncoated—Polished to eject chips, these are also known as bright finish bits.

Carbide Drill/Mill End Mills

Drill/Mill Cut

Style

2 Flutes

4 Flutes

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.

Uncoated Carbide—Use uncoated end mills for general purpose milling and short production runs.

Titanium Nitride (TiN)-Coated Carbide—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. 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 Aluminum Nitride (TiAlN)-Coated Carbide—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. 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.

2 Flutes—End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.

4 Flutes—End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds.

Drill/Mill End Mill Sets


Drill/Mill Cut Style

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.

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.

Uncoated Cobalt Steel—Use uncoated end mills for general purpose milling and short production runs.

Titanium Nitride (TiN)-Coated Cobalt Steel—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.
