Festool 492525 CE self-centering bit 5mm

5mm Centrotec self-centering drill bit. The Centrotec shank is designed for use with the Festool Centrotec System, as well as with all standard or keyless chucks for no-slip performance. The Centrotec System was designed to provide a seamless transfer of force, eliminating bit slippage or marring of the drill bit. The weight of the drill is reduced by nearly ½ pound, and the length is reduced by nearly 1-1/2” with the Centrotec System. Most importantly, the Centrotec system offers a quicker and more secure means of bit change than any other quick-change chuck system.
