The 4mm Spiral Drill Bit with Centrotec Shank provides precise, compact, and durable solution for drilling wood, metal, and plastic. Precision-ground HSS steel stays sharp longer for precise hole drilling and long service life. Centrotec shank can also be used with all standard three-jaw chucks for no-slip performance. The Festool Centrotec System is designed to deliver better transfer of force between the drill and the bit, with no chance for bit slippage or marring of the drill bit. The Centrotec Chuck design enables full 1/2"pound reduction in weight, and reduces the overall length, or clearance, by nearly 1-1/2"inches. The quick-change Centrotec system delivers faster, more efficient means of changing bits and driver tips than any keyless chuck system, and virtually eliminates run out.
