[NEW VERSION] The improved pneumatic chamfering machine features a redesigned shell with high quality bearings and is equipped with precision heat treated tungsten steel blades. It is robust and durable, delivering high cutting performance and long service life. [CLEVER DESIGN] Five stage air valve control allows you to freely set the required feed speed. Chamfer width can be adjusted from 0.1 mm to 1.5 mm. The 360 degree rotating exhaust outlet provides effective heat dissipation and high work efficiency. A safety switch helps prevent accidental contact and protects the user at all times. [PERFORMANCE] Free speed can reach up to 30000 rpm, with an air consumption of 0.4 m3/min. Designed to withstand high impact and high speeds with high concentricity, low vibration, low wear, and longer life. The speed improves and the bevels become smoother. APPLICATIONS - Deburring and chamfering metal edges after punching or cutting - Chamfering and deburring wooden and plastic workpieces for clean joints - Beveling pipe ends or fittings for easier assembly in automotive, plumbing, or fabrication work
