## Summary description

Proline 27251 hole saw with a 5.1 cm cutting diameter, supplied as a single piece. Designed for creating clean circular openings in materials compatible with hole saw use. Suitable for drilling tasks that require a 5.1 cm bore, such as installing pipes, conduits, or hardware fittings. Compatible with standard arbors and power drills that accept hole saw attachments.

## Long description

The Proline 27251 hole saw has a cutting diameter of 5.1 cm and is supplied as a single piece for use with compatible power tools. Constructed with vacuum-soldered diamond abrasive, this hole saw is intended to produce clean circular openings in hard surfaces such as ceramic tiles, stone tiles and stoneware. The tool features an M14 threaded shank for direct mounting on angle grinders and can be adapted for combi drills using an adapter with a centering drill when applicable. It is designed for dry drilling operations.
Advantages
Diamond abrasive applied by a vacuum soldering process ensures consistent cutting performance and extended wear resistance on hard, brittle materials. The M14 threaded shank allows direct installation on angle grinders without additional fittings, simplifying setup for tile and stone work. Its 5.1 cm diameter meets common needs for installations that require a medium-sized bore, while compatibility with an adapter and centering drill enables use with combi drills when a minimum 20 mm hole saw specification is met.
Suitable for
Cutting circular openings in ceramic tiles
Drilling holes in stone tiles and stoneware
Creating passages for pipes, conduits and fittings in tiled surfaces
Tasks requiring a 5.1 cm bore where diamond cutting is required
Key specifications
Cutting diameter: 5.1 cm
Abrasive: vacuum-soldered diamond
Shank connection: M14 threaded shank for angle grinders
Suitable materials: ceramic tiles, stone tiles, stoneware
Sold as: single piece
Drilling method: dry drilling recommended
How to use
Mount the hole saw on an angle grinder using the M14 thread or fit an appropriate adapter and centering drill when using a combi drill, ensuring the adapter is compatible with the hole saw size. Secure the workpiece and mark the centre of the required opening. Start drilling at low speed to establish the cut, then apply steady, moderate pressure while maintaining tool alignment to avoid chipping. Because this hole saw is intended for dry drilling, avoid using liquid cooling; allow periodic pauses if the tool or material becomes excessively hot.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, gloves and a dust mask. Ensure the work area is secure and avoid excessive lateral force on the hole saw to prolong diamond life. For best results on brittle tiles, consider scoring or supporting the rear of the tile to reduce breakout.
