Made of an abrasion-resistant carbide designed for turning cast iron, these inserts will last longer than inserts for multiple materials.

Optimized for use on steel, these inserts can run at higher cutting speeds and will last longer than inserts for multiple materials.

Cut aluminum, copper, brass, and other non-ferrous materials with these premium inserts.

When it's time to replace the screws in a carbide insert holder, use the reference number on your holder to find the right size.

Combine a holder and carbide insert to perform cutoff and grooving tasks on a lathe.

Cut square corner grooves in a workpiece or cut completely through a part.

Install these inserts into a compatible holder to cut external or internal threads on a workpiece.

Combine a carbide insert with a compatible internal profiling holder to create a tool that can contour the interior wall of a hollow workpiece.

Replace Torx keys and screws for boring carbide insert holders with coolant hole.

Fasten carbide inserts directly to these end mills for a hold that's strong enough to handle the high speeds of a CNC machine. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire end mill.

Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire end mill.

These jobbers'-length bits have the rigidity and length required for most applications.

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.

These jobbers'-length bits have the rigidity and length required for most applications.

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.

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits.

Multiple cutting edges on the tip allow these bits to drill quickly through natural stone, granite, and other hard, abrasive material.

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.

Harder, stronger, and more wear resistant than carbide-tipped 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 spear-shaped point drills smoothly through glass and ceramic.

The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers.

Bore clean, flat bottom holes in soft wood, veneer, and laminates.

Use these bits with handheld power drills and hammer drills set to rotary-only mode.

Use these bits with handheld power drills, drill presses, and hammer drills.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

Drill holes up to 1 1/2" in diameter.

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.

Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size.

Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.

A more controlled chip removal reduces heat buildup. Use these bits on brittle materials such as block and brick.

The bits in these sets have rubber blended into the abrasive, which cushions during grinding to produce a smooth to extra-smooth surface texture.

Best for grinding composites, fiberglass, plaster, plastic, rubber, and wood without generating heat, these sets include a selection of our most popular tungsten carbide bits.

The abrasive grains in these discs are blended with rubber, which cushions during grinding to produce a smoother surface texture than other discs with similar grits. Discs attach to your grinder with a shank.

The diamond abrasive in these bits is extremely hard and lasts longer than tungsten carbide. For longer tool life and improved finish, use a water- or oil-soluble mist or coolant.

Finish the edges of metal, polymer, and plastic 3D printed parts with the bits, burs, wheels, and brushes in these kits.

The perforated honeycomb pattern cuts carbide, ceramics, and glass without the need for cleaning.

Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces.

A nickel-coated diamond grit and synthetic resin bond make these wheels extremely hard and wear resistant.

Designed to stand up to heavy use, these wheels remove more material than our general purpose grinding wheels.

Silicon carbide cuts through concrete and stone without generating much heat. Wheels are also known as Type 27 wheels, raised-hub wheels, and grinding discs.

Multiple layers of nylon mesh embedded with abrasive provide a cushioned grind. Also known as unitized discs or wheels.
