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

These hollow bits are diamond-tipped for long life and fast cutting speeds. Only for use in drill presses.

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.

Sets contain an assortment of tools for grinding, sanding, and cutting on small surface areas.

A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they’re cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits.

Best for intricate, precise grinding jobs on metal, ceramic, and plastic, these sets include diamond abrasive bits with different head shapes.

When cutting threads in nonferrous and nonmetallic materials, such as aluminum, copper, fiberglass, and plastic, diamond tips provide superior cutting performance.

With a diamond coating, these bits resist wear when used on ceramics and other highly abrasive material. All have a square cut style to create slots, pockets, and edges.

These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite.

The toughest bits available, these withstand the shock and twisting force of impact drivers.

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

The toughest bits available, these withstand the shock and twisting force of impact drivers. Designed for screws with a square recess in the head, they are also known as Robertson bits.
