Diamond Sharpening Disc MAR-POL MAR-POL TARCZA DO OSTRZENIA 150 mm, bore sizes 32/30/25/20/12.7 mm

Diamond sharpening disc MAR-POL is a 150 mm abrasive wheel designed for sharpening and restoring edges on metal tools and hard materials. The disc is compatible with multiple bore sizes (32, 30, 25, 20 and 12.7 mm), which makes it suitable for mounting on a wide range of arbors and grinding machines. Constructed with a diamond abrasive layer, the wheel delivers consistent material removal for maintenance, reprofiling and light grinding tasks in workshops and service areas.

Advantages

The diamond abrasive provides high cutting efficiency and long wear life compared with conventional abrasives, ensuring steady performance during repeated use. Multiple bore sizes increase versatility and reduce the need for adapters when switching between machines. The 150 mm diameter balances removal speed and control, enabling precise edge restoration while maintaining operator control. The disc is suitable for contact with hardened surfaces and delivers predictable results on tool edges.

Suitable for

• Sharpening hand tools (chisels, plane blades, knives)
• Reprofiling small cutters and drill bits
• Maintaining edges on workshop implements
• Light grinding and deburring of hardened parts
• Use in bench grinders and compatible grinding machines

Key specifications

• Diameter: 150 mm
• Available bore sizes: 32 mm, 30 mm, 25 mm, 20 mm, 12.7 mm
• Abrasive type: diamond-coated surface
• Intended use: sharpening, edge restoration, light grinding
• Typical mounting: centered bore for direct arbor fit

How to use

Mount the disc on a compatible grinder or arbor using the bore size that matches the machine spindle or an appropriate adapter. Ensure the wheel is secured and concentric before operation. Operate at the machine’s recommended speed for diamond-coated wheels and apply light, steady pressure when contacting tool edges to avoid overheating. Use cooling or intermittent contact if prolonged grinding is required to preserve diamond bond performance and to prevent thermal damage to the workpiece.

Usage recommendations

Prior to first use, inspect the disc for any visible damage and confirm correct mounting. Wear appropriate personal protective equipment such as safety glasses, gloves and hearing protection. Store the disc in a dry, stable environment and avoid dropping or striking the abrasive surface.
