Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.

Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

Don't lug around a toolbox full of drivers—just swap out the bit to drive multiple screw sizes and styles with one tool. The ultimate space savers, these bit screwdrivers are a smart solution for on-the-go jobs.

Drill and ream holes for taper pins with the same tool. These tools have chip breakers on the cutting edge.

More durable than our light duty drills, these are excellent for general purpose drilling jobs.

Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

With a higher helix angle than standard high-speed steel end mills, these clear more chips and generate less heat, making them good for milling soft material, such as aluminum, brass and bronze. They are center cutting for making plunge cuts into surfaces and have a square-end cut style for milling square slots, pockets, and edges.

End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
