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.

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

Drive multiple screw styles and sizes without lifting and repositioning your tool. A ratcheting handle drives screws with smooth, continuous motion to save time with every turn. Just snap one of the included bits onto the shaft and get cranking.

Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds without sacrificing tool life. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as stainless steel, titanium, and tool steel. They have a coarse pitch and create large chips, so they’re also more efficient when working on soft metals such as aluminum, brass, and bronze. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

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.
