Diamond Hole Saw GRAPHITE 22 mm with M14 shank, model 55H306

Diamond Hole Saw GRAPHITE 22 mm with M14 shank (model 55H306) is a cutting accessory intended for drilling precise round openings up to 22 mm in hard materials such as ceramic, tile, glass and stone. The tool uses a diamond-segmented cutting edge that provides wear resistance and consistent cutting performance. The M14 threaded shank enables direct mounting to angle grinders and other power tools that accept M14 accessories, offering a rigid connection and straightforward setup for renovation, tiling and construction tasks.

Advantages

The diamond cutting edge ensures long tool life and maintains cutting efficiency when working with abrasive and brittle materials. The 22 mm diameter is suitable for common fixture and anchor holes while providing accurate, smooth cuts with minimal chipping. The M14 shank offers compatibility with a wide range of angular grinders and adapters, enabling quick changeover and stable operation. The overall design balances cutting speed with control to reduce the need for finishing work around the hole.

Suitable for

• Drilling holes in ceramic tiles during bathroom and kitchen renovation
• Cutting openings in glass and mirrors for fixtures and fittings
• Creating holes in natural and artificial stone for anchors or piping
• On-site jobs requiring angle grinder-mounted accessories

Key specifications

How to use

Securely mount the hole saw onto the M14 spindle of a compatible angle grinder or adapter according to the power tool manufacturer's instructions. Mark the drilling point on the workpiece and, if possible, use a guide or tape to reduce slipping. Start at low speed to position the cutter, then apply steady light pressure and increase speed as the diamond edge engages the material. Use periodic pecking motions or back off occasionally to clear debris and reduce heat buildup. For best results in brittle materials, keep the cutting area cooled if appropriate and avoid excessive lateral force that can cause cracking.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, gloves and hearing protection. When drilling tiles, support the workpiece to prevent vibration and consider applying water or a coolant to extend the life of the diamond edge and reduce dust. Follow the angle grinder manufacturer's guidelines for safe mounting and operation of M14 accessories.
