The NSK Impulse NA45-230 Air Grinder is the ideal tool for precision engineering professionals working in demanding environments such as aerospace, automotive prototyping, tool & die manufacturing, and micro-component machining.
Built with NSK’s trusted Japanese craftsmanship, the NA45-230 combines ultra-high-speed performance (from 23,000 RPM) with outstanding stability and control. Its compact, lightweight body enables precise handling for detailed work in tight or delicate areas, making it a top choice for engineers needing accuracy down to the micron level.
NSK Impulse NA45-230 air grinder with 45° head for surface grinding and sanding, or mounted point and carbide burr functions. The grindstone axis can be used with the Topcut stones or rubber pad with self-adhesive discs, but can be replaced with 3mm (or optional size) collet. Suitable for surface grinding with cup-shaped grindstone.
The NSK NA45-230 pneumatic grinder is a high-torque air motor in pursuit of maximum efficiency of air. With a special rotary vane motor, the MPULSE allows less drop in speed caused by fluctuations in load, and maintains speed under no-load at all times, to ensure stable grinding. The twist-free mechanism prevents hose twisting. Low noise levels with the use of the fitted silencer. Airline kit will relieve heat-up problem of motor at long continuous operation. Rotating speed is adjustable by the on/off ring at the end of the grip.
