• 3.5mm fully adjustable countersink drill bit with depth stop
• Depth stop rotates freely, eliminating burning or marring of your finished surface
• Save money by only having to replace the bit and not the entire assembly
• Long, precision milled hex shank eliminates wobble, or run out during use

4.5mm adustable countersink drill bit with a free spinning depth stop for use with the Centrotec system. The Centrotec shank can be used with all three-jaw chucks for no-slip performance or in conjunction with Festool's Centrotec chuck system. With the Centrotec design there is a better transfer of force with no chance for bit slippage or marring of the drill bit. Reduce the weight of the drill by nearly ½ pound and the length by nearly 1-1/2” with the Centrotec system. Additionally the Centrotec system offers a quicker way of changing bits than a keyless chuck with less run out.
