Bosch Expert Power Change Plus HSS-CO Pilot Drill Bit

The Bosch Expert Power Change Plus HSS-CO Pilot Drill Bit is a replacement pilot drill designed to guide hole saws accurately and prevent wandering during use.

Engineered specifically for the EXPERT Power Change Plus keyless arbor system, this pilot drill clicks securely into place without the need for screws or bolts. The reinforced shank and close-fitting design deliver a stable, precise connection — more rigid than conventionally mounted hole saws — helping you achieve cleaner, more accurate cuts.

Manufactured from high-speed steel blended with 5% cobalt (HSS-CO), the drill offers excellent resistance to heat and wear, making it well suited to demanding applications in steel and stainless-steel sheet. It pairs directly with the EXPERT Sheet Metal PC Plus hole saws, ideal for electricians, fabricators, and contractors working with metal sheet materials.

The keyless interface makes swapping pilot drills and hole saws quick and straightforward on site, reducing downtime without compromising the security of the connection.
