Drill/Mill Cut

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.

Fast-Cut Router Bits

Quickly make smooth plunge cuts—the staggered flute design, drill/mill cut style, and carbide coating on these bits let them cut at higher speeds than other router bits. Staggered flutes combine the fast chip clearing and cutting speeds of straight flutes with the smooth finish of spiral flutes. The flute switches sides halfway up the shaft, making the bit more balanced and better at producing clean finishes than standard router bits. These bits have a pointed end, making downward plunge cuts easy.

Made of carbide-tipped high-speed steel, these bits provide faster cutting speeds and a longer tool life than standard high-speed steel bits. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

Drill/Mill Router Bits

Drill, mill, and trim with the same bit. The unique shape on these bits was originally used for aircraft panels. They have a pointed end and spiral flutes, like a drill bit, making downward plunge cuts easier than with square-cut and straight-flute bits. The spiral flutes also leave a smoother finish. The flutes lift chips up from the workpiece for applications that require a clean finish on the bottom edge of the cut. Securely clamp your material before routing to prevent lifting.

These bits are made of high-speed steel for general purpose use. They can be used with hand tools, router tables, and CNC machines. These bits do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

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.

Diamond-Coated Router Bits for Composites

With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.

Drill/Mill Cut Style—Bits with a drill/mill cut style have a pointed end for easier plunge cuts than square-cut bits.

Plunge Cut—Plunge-cutting bits let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work such as trimming, contouring, and finishing.

Straight Flutes—Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.

Diamond-Pattern Flutes—Diamond-pattern flutes' small, staggered teeth aggressively cut, yet leave a smooth finish.

Replaceable Carbide-Insert Drill/Mill End Mill Holders


Drill/Mill Cut Style	End Mill Body Shown with Inserts (Sold Separately)

Fasten one insert to the center of these end mills and three more to the sides, and you can use them for drilling, shoulder milling, contouring, and finishing. When the cutting edges dull, switch out the inserts instead of replacing the whole tool. These end mills help you reduce waste and costs in high-volume jobs. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine.

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.
