Designed for cutting telephone and computer wire grommet access holes in office furniture. All tools feature precision ground and tempered tool steel, multi-tooth cutting edges for faster cutting and chip removal, and a massive cutter body to dissipate heat and resist burning. All are 1/2″ shank.

TIPS AND WARNINGS

• Making repeated shallow cuts and allowing the bit to cool for two or three seconds between passes will increase the life of your bit. Overheating caused by chip buildup or constant contact with the cutting surface will remove the temper from the bit’s cutting edges.
• You can also extend the life of your bits by not exceeding the maximum speed recommended for the type of wood. Applying excessive force to the bit while drilling will also cause overheating.
• Remove all the chips from the previous hole before boring a second or subsequent hole when mortising.
• Always wear proper eye and hearing protection when working with power tools.
