Pferd Polinox PNER Unitized/Convolute Grinding Wheel

• POLINOX Wheels Unitized Disc
• POLINOX unitized discs are used for facedown grinding on speed-adjustable angle grinders. The compressed fleece is bonded to a glass woven base. The PNER discs are particularly suitable for working larger surfaces on stainless steel (INOX) components.
• Abrasive: Silicon carbide SiC

Recommendations for use

• When working on materials with poor heat conductivity, e.g. titanium and stainless steel, significantly reduce the cutting speed
• Flexible shafts, electric and air-powered straight grinders as well as angle grinders and fillet weld grinders can be used as tool drives
• Designed for use on straight grinders and flexible shaft drives. Particularly suitable for work on small surfaces of stainless steel (INOX) and titanium alloy components.
• Unmounted grinding wheels with diameter 150 mm can also be used on grinding blocks, for reworking surgical instruments for example.
• POLINOX unitized discs achieve their best performance at a recommended cutting speed of 35 m/s

Safety notes

• For safety reasons, it is imperative to remain within the stated maximum permitted rotational speed at all times
