Fits any quick change system including Festool's Centrotec. FISCH hex shank quick change metal twist drills are universal and will fit into all hex shank and quick-change systems. These special short shank bits have a twin-ground, double facet tip which produces a unique central point, improving centering accuracy and producing rounder and more precise holes. The multifacet drilling geometry eliminates the need for a prior centre punch hole and has a longer drilling life than standard geometry drill bits. They stay sharper for longer and work extremely well in a cordless drill. They are made to a very high standard, giving excellent clean cuts for long periods of use. They are ground from one piece giving the bit extra strength. They are perfect for drilling sheet metal and most other metals, as well as wood and some plastics. The 1/4” universal quick change shank is hardened to DIN3126.E6.3. Available in 3,4,5,6,8 and 10mm. Made in Austria.
