Set of 30 Aluminum Oxide Grinding Wheels Compatible with Rotary Tool Sanding Bits with 1/8" Shank for Polishing Grinding Bit Carving Metal Deburring (3 Shapes)

Three functional formats: 10 mm cylindrical sanding bits for flat surfaces, edge deburring and shallow grooves. 15mm cylindrical sanding bits, elongated for deeper cuts or larger surface finishes. 10mm ball or conical tip sanding bits for narrow corners, curved surfaces or fine contours. Aluminum oxide grinding wheels are made of high quality material with a Mohs hardness of 9, surpassed only by white corundum. This ensures a long service life and precise grinding results, even on hard materials such as stainless steel or granite. The sharp cutting edge and conical shape of the cordless screwdriver grinding wheel allow for perfect treatment of complex areas inaccessible to conventional abrasives. The curved surface is used for metal bodies and tubes. The grooved structure is used for engine parts and electrical housings. Fine details are used for jewelry and gemstone work. Compared to conventional grinding wheel, processing time can be reduced by up to 40%. The polishing of stainless steel creates a smooth surface like a mirror, without scratches or dents. The porous structure of corundum reduces dust production by up to 30% and noise by 15dB compared to polishing accessories. Works on metal, stone, ceramic, glass and plastic without damaging the surface. The 1/8 inch shank fits most power tools with a 3.175 mm chuck. Safety Tips: Wear protective goggles and dust mask. Set the speed to 8,000 to 12,000 rpm. Make sure the tail is tight. This set of 30 pieces includes enough rotary tool replacements for large projects or commercial applications.
