⚡ At a Glance
- • Cutting Quality: HSS-Co construction keeps the edge hard and heat-resistant for cutting stainless steel and metal profiles.
- • Best for: Tradespeople and serious DIYers who use hole saws on metal regularly
- • Not ideal for: Users who only drill light wood or plastic infrequently
Pilot drill designed for use with the Bosch Power Change Plus keyless arbor and PC Plus arbor compatibility. Sized 7.15 x 105 mm and suited to Expert Tough Material and Construction Material hole saws with a 60 mm cutting depth.
Faster changeovers - with Quick Change System
Quick Change System mates with the Power Change Plus keyless arbor to allow tool-free swaps; pilot geometry locks into the arbor for repeatable alignment. The pilot is built to engage securely so the hole saw centres immediately on the workpiece.
Speedier bit swaps cut downtime when moving between hole-saw sizes, helpful on busy sites or multi-material jobs.
Neat, accurate starts - with PC Plus arbor fit
Pilot shaft dimensions match the PC Plus arbor to centre the hole saw and prevent wandering during initial contact. Length and diameter (7.15 x 105 mm) provide stable guidance through the cut.
Cleaner, more consistent holes in stainless steel sheets and profiles, reducing the need for rework or filing.
Durability under load - with HSS-Co composition
High-speed steel alloyed with cobalt increases hardness and resistance to heat when drilling metal. The HSS-Co formulation helps retain edge geometry during prolonged use.
Maintains sharpness longer when cutting tough materials, meaning fewer replacements and less interruption on longer jobs.
