D Type Spherical Burr Compatible Electric Die Grinder

Ball Shape Advantages:The spherical head forms arcs and inner radii in one pass, reaches hard-to-access curved dead corners, and delivers smooth grinding surfaces to cut polishing time.

Flat bottomed silver soldering: using a sandwich silver solder material containing 50% silver; The welding area is large and without gaps; Reduce damage to tungsten steel raw materials and lower weldi

Double-sided grinding of steel shanks: After grinding, the ends of the steel shanks are flat and free of burrs, with high dimensional accuracy and compliant concentricity; this significantly improves
