For use with the Bosch Power Change Plus keyless arbor. High Speed changing hole saws and drill bits - This keyless system does not require fixing with screws or bolts. You just pull one hole saw out and push another in. Despite this apparent simplicity, the EXPERT Power Change Plus still gives a firm connection: with a reinforced shank and close-fitting guide drill, it actually has less play than conventional systems.
PUNK HSS-G Drill Bits are fully ground hardened with a split point tip, which reduces the need for pilot holes up to 10mm diameter. HSS-G treatment strengthens the bit to deliver up to 40% faster drilling than standard rolled drill bits.
