Explore our HSS drill bits range, suitable for quickly and efficiently drilling into steel, cast iron, non-ferrous metals and hard plastics. Available in a selection of sizes to suit your project.
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.
