4.10 mm Twister Brad Spur Drill

The M.A. Ford 20716140 is a new pneumatic accessory designed for precision drilling tasks. It suits professionals and hobbyists who need a dedicated brad and spur bit for clean hole starts in wood or similar materials.

Twister flute geometry for chip clearance

The Twister flute profile helps evacuate chips during use, reducing binding and heat build-up. A 4.10 mm cutting diameter fits standard chucks and collets, so the bit mounts quickly on common pneumatic drills without adapters.

California Proposition 65 chemical warning

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Buyers who require materials without such substances should select an alternative drill bit.
