Pneumatic die grinder L-25B, 27.000 min-1 - Nitto Kohki 180800001

In mould making and casting rework, speed decides whether a mounted point cuts cleanly or merely rubs. These die grinders reach 27,000 to 56,500 rpm at a weight of 0.27 to 0.6 kg and accept tools with 3 or 6 mm shanks.

• Free speeds of 27,000 to 56,500 rpm keep small mounted points in an efficient cutting speed range.
• Collets for 3 and 6 mm shanks cover everything from fine points to standard mounted wheels.
• Weights from 0.27 kg make the tool pen-like to guide and reduce hand load on detail work.
• Air consumption of 0.17 to 0.4 m³/min stays within a normal workshop supply.
• Mounted wheels, spanners and an adaptor bushing are included, so the tool is ready once connected.

Applications

• Rework on castings and gate areas
• Cutting radii and contours in mould making
• Deburring bores and cross-drilled holes
• Detail work on welds in confined spaces
• Adjusting fits on fixtures and gauges

Standard accessories

• Single Ended Spanner 14mm : 1 pc.
• Mounted Wheel No.2 : 1 pc.
• Mounted Wheel No.3 : 1 pc.
• Chunk Pin : 1 pc.
• Bushing PT1/4 x NPT 1/4 : 1 pc.

Operating principle

The air motor drives the collet with the fitted mounted point. Quoted speeds are no-load values and fall as load rises, so hose bore and supply volume should match the stated air consumption.
