Pneumatic die grinder AL-55A, 56.500 min-1 - Nitto Kohki 184500001

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.

Technical data

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.
