Hole saw Proline 27222, 22 mm diameter, 1 piece

Proline 27222 is a 22 mm diameter diamond hole saw designed for precise circular cutting in hard surfaces. Constructed with vacuum-soldered diamond segments, this single-piece hole saw is intended for use on angle grinders with an M14 threaded shank and can be adapted for combi drills with a centering drill where applicable. It is suitable for creating clean openings for cable passages, pipe fittings and other installations in ceramic and stone materials when dry cutting is required.

Advantages

The vacuum-soldered diamond cutting edge ensures consistent cutting performance and extended life on abrasive materials such as ceramic tiles, stoneware and natural stone. The M14 threaded shank allows direct mounting on compatible angle grinders for stable operation and straightforward setup. Its 22 mm diameter provides a standard size for small penetrations while the single-piece design simplifies handling and storage.

Suitable for

• Drilling openings in ceramic tiles and porcelain stoneware
• Creating holes in natural stone and similar brittle stone materials
• Making cable or pipe passages through tile, stone and hard ceramic panels
• Use with angle grinders fitted with an M14 threaded arbor

Key specifications

• Cutting diameter: 22 mm
• Cutting edge: vacuum-soldered diamond segments
• Shank thread: M14 for direct mounting on angle grinders
• Construction: single-piece hole saw
• Recommended cutting mode: dry drilling

How to use

Mark the centre of the intended hole on the workpiece and secure the material to prevent movement. Attach the hole saw to an angle grinder with an M14 thread or use an appropriate adapter and centering drill when converting for combi drill use. Start the tool at low speed to establish the cut, then apply steady, even pressure while maintaining tool stability. Drill in short, controlled intervals to avoid overheating and check progress frequently. Because this product is designed for dry drilling, do not apply water during operation.

Usage recommendations

For best results on brittle and heat-sensitive materials, use moderate speed and avoid excessive feed pressure. Ensure the workpiece is firmly clamped and use protective equipment such as eye protection, gloves and respiratory protection for dust. When adapting the hole saw for use with a combi drill, use a compatible centering drill and adapter meant for hole saws of at least 20 mm diameter.
