Diamond Hole Saw 10 mm, Expert+ MN-76-210, M14 shank, max 12,000 rpm

Diamond Hole Saw 10 mm Expert+ MN-76-210 with M14 shank is a compact cutting tool designed for creating precise small-diameter holes in hard construction and finishing materials. The bit is intended for use in angle grinders and rotary tools equipped with an M14 threaded arbor and is specified for a maximum operating speed of 12,000 rpm. The segmented diamond cutting edge enables controlled penetration into ceramic, tile, porcelain, glass and natural stone while maintaining a slim 10 mm hole diameter.

Advantages

The diamond-segmented edge provides fast cutting performance and consistent hole geometry with minimal chipping on brittle surfaces. The M14 threaded shank grants secure attachment to compatible angle grinders and some rotary tools without additional adapters. A maximum recommended speed of 12,000 rpm helps to match the tool to the correct operating range and reduce the risk of overheating. When combined with water cooling, the cutter achieves longer abrasive life and lower dust generation.

Suitable for

• Drilling small diameter holes in ceramic and porcelain tiles
• Creating openings in glass and glazed surfaces for fixtures
• Cutting precise holes in natural stone and engineered stone tiles
• Installation tasks that require tidy 10 mm holes for anchors, cables, or fittings

Key specifications

• Cutting diameter: 10 mm
• Shank type: M14 threaded shank for angle grinders and compatible rotary tools
• Maximum operating speed: 12,000 rpm
• Cutting material: diamond-segmented edge suitable for hard and brittle materials
• Recommended cooling: wet (water) cooling to extend tool life and reduce dust

How to use

Securely install the M14 shank into the tool spindle according to the tool manufacturer's instructions and ensure the accessory is tightened before operation. Mark the drilling point on the workpiece and start at low speed to establish the drilling position; then increase speed up to, but not exceeding, 12,000 rpm. For brittle or glazed surfaces, apply light steady pressure and avoid sudden lateral forces to prevent cracking. Where possible, supply a steady flow of water to the cutting zone to cool the diamond edge, remove debris and limit dust.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and a dust mask or respirator when dry cutting. Prefer wet cutting with continuous water feed for best life and dust reduction. Match the operating speed to the material and tool instructions and avoid excessive side loads to preserve cutting edge life.
