Abrasive Mounted Point KLINGSPOR 40×20 mm K40 with 6 mm shank (model 12942)

The KLINGSPOR abrasive mounted point 40×20 mm with K40 grit and a 6 mm shank is designed for precision material removal, deburring and surface finishing in metalworking and tool shops. This mounted point is suitable for use with rotary tools and die grinders that accept a 6 mm shank. The cylindrical head size provides a balance between contact area and access to tighter contours, enabling controlled grinding on small and medium workpieces.

Advantages

The abrasive composition and K40 grit deliver efficient stock removal while maintaining a predictable wear pattern for consistent performance. The 6 mm shank ensures secure fitting in standard collets and chucks for rotary tools. The mounted point’s dimensions make it appropriate for both flat and slightly contoured surfaces, offering versatility for precision finishing and deburring tasks in metal and harder materials.

Suitable for

• Precision grinding of small metal parts
• Deburring edges and grooves
• Surface finishing and blending on welded joints
• Detail work on molds, dies and tools
• Preparing metal surfaces prior to coating or painting

Key specifications

• Head diameter × length: 40 × 20 mm
• Abrasive grit: K40 (coarse)
• Shank diameter: 6 mm
• Shape: cylindrical mounted point
• Material compatibility: ferrous and non-ferrous metals, hardened surfaces

How to use

Install the mounted point in a compatible rotary tool or die grinder, securing the 6 mm shank firmly in the collet or chuck. Operate the tool at the manufacturer’s recommended speed for abrasive-mounted points and for the specific material being worked; avoid excessive pressure—let the abrasive do the cutting. Use steady, controlled movements and approach the workpiece at appropriate angles to achieve the required surface finish. Replace the mounted point when wear reduces effectiveness or if the abrasive becomes uneven.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, gloves and respiratory protection when grinding. Match rotational speed to the mounted point’s rating and the base material to avoid overheating or premature wear. Store mounted points dry and protected from mechanical damage.
