The Universal Quick Change shanks fit into any quick-change system including Festool CENTROTEC. The set comprises sizes 3, 4, 6, 8, 10 and 12mm. These bits are perfect for use in a cordless drill. Made to a very high standard, these brad point twist drills give exceptional clean cuts time after time. For strength, they are ground from a single piece. For a clean, fast cut, the centre point has two cutting spurs that scribe a very clean entrance hole. The specially ground flute with twin spiral lands quickly clears waste. This keeps the drill bit straight and true, for a fast cut. DIN3126.E6.3 form hardened 1/4" quick-change shank. Made in Austria.
