## Summary description

Bosch drill accessory: an adapter for hole saws (PC) with an 8.7 mm connection paired with a replacement HSS-G pilot drill 7.15×65 mm. The set provides secure centering of hole saws and a hardened high-speed steel pilot for starting and guiding cuts. Suitable for use with compatible hole saw systems and standard drills for precise circular drilling tasks.

## Long description

Bosch adapter for hole saws PC with an 8.7 mm connection combined with an HSS-G pilot drill 7.15×65 mm is a drill accessory designed to provide accurate centering and reliable guiding when cutting circular holes. The adapter fits compatible hole saw systems and standard drill chucks that accept the specified connection diameter. The included high-speed steel pilot drill is hardened to ensure clean starts and improved resistance to wear during repeated use.
Advantages
The adapter and pilot combination ensures secure centering of hole saws and stable guidance throughout the cutting operation. The HSS-G pilot drill offers good hardness and drilling performance in common construction materials, while the adapter's connection diameter provides compatibility with a range of hole saws. The design supports repeatable, concentric hole cutting and reduces wobble compared to using a pilot-only arrangement without a proper adapter.
Suitable for
 Circular hole cutting in wood, soft metals and composites when used with a compatible hole saw
 Preparation of openings for pipes, cables, vents and fittings
 Renovation and installation tasks requiring precise centering of hole saws
When it may not be suitable
This adapter set is intended for use with compatible hole saw systems and standard drills that accept an 8.7 mm connection; it may not fit specialty hole saws or arbors with different connection standards. The HSS-G pilot drill is designed for general purpose use and may not be optimal for very hard materials such as hardened steel or reinforced concrete where carbide or specialized masonry pilots are required.
Key specifications
 Adapter connection diameter: 8.7 mm
 Pilot drill type: HSS-G (high-speed steel, ground)
 Pilot drill dimensions: 7.15 × 65 mm (diameter × overall length)
 Material hardness: hardened high-speed steel for the pilot
 Compatibility: intended for use with compatible hole saws and standard drills
How to use
Install the adapter into the hole saw according to the hole saw manufacturer's instructions and secure it firmly. Insert the HSS-G pilot drill into the adapter and tighten as required by the adapter's fastening system. Mount the assembled hole saw and adapter in the drill chuck, ensuring the drill is held securely. Begin drilling at low speed to allow the pilot to establish the center, then increase speed as appropriate for the material and hole saw size. Apply steady pressure and keep the drill perpendicular to the workpiece to maintain concentric cutting.
What to consider before purchase
 Verify that your hole saw system accepts an 8.7 mm adapter connection
 Check that the pilot diameter 7.15 mm and length 65 mm suit your drilling depth and hole saw size
 Consider the materials you will cut and whether an HSS-G pilot is suitable for those materials
Usage recommendations
For best results use steady speed and moderate pressure, ensure correct fastening of adapter and pilot, and cool the pilot when drilling extended runs to prolong tool life. Replace the pilot if signs of wear or dulling appear to maintain accurate centering and clean hole edges.
