Diamond Hole Saw Expert+ 12 mm with hex shank (model MN-76-312) is a precision diamond cutting tool designed for creating clean 12 mm openings in hard surfaces. Compatible with drills and rotary tools that accept hex shanks, this hole saw is rated for operation up to 3200 rpm and is intended for use on ceramic, porcelain, tile and similar materials where a diamond edge provides accurate, low-chipping cuts.
Advantages
The carbide-bonded diamond edge enables fast, consistent drilling through hard tiles and ceramics while minimising chipping around the hole perimeter. The 12 mm diameter produces uniform openings for anchors, pipes or fittings, and the hex shank ensures secure, slip-resistant attachment to compatible drill chucks and quick-change adapters. Rated for up to 3200 rpm, the tool balances cutting speed and control when used at appropriate feed pressure.
Suitable for
- Drilling 12 mm holes in ceramic and porcelain tiles
- Creating openings for plumbing pipes and fittings
- Installing anchors or dowels in tiled surfaces
- Precision work in bathroom and kitchen tiling
Key specifications
- Cutting diameter: 12 mm
- Shank type: hex shank for secure grip
- Maximum rotational speed: 3200 rpm
- Cutting material: diamond-bonded edge suitable for hard surfaces
- Intended materials: ceramic, porcelain, tile and comparable hard surfaces
How to use
Secure the hole saw to a compatible drill or rotary tool with a matching hex chuck or adapter. Mark the drilling position on the workpiece and, if possible, start with a small pilot mark or use tape to reduce surface slipping. Use low to moderate drill speed, not exceeding 3200 rpm, and apply steady, even pressure without forcing the tool. For ceramic and porcelain, intermittent drilling with light pressure and periodic withdrawal helps clear debris and prevents overheating. Cooling with water spray or a damp cloth is recommended for prolonged cuts.
Usage recommendations
For best results, use the hole saw with variable-speed drills and maintain speeds below the 3200 rpm rating. Employ water cooling or frequent pauses when cutting dense materials to extend the diamond edge life. Wear appropriate eye protection and gloves, and secure small tiles to prevent movement during drilling.
