CLEAN, FINISHED EDGES on leather projects are as easy as using these sleek leather burnishing tool tips. Affixed in your rotary tool, electric drill or drill press, they finish tight corners, small holes and edges more easily than if done by hand. 2-PIECE SET includes a pointed burnisher tip that is ideal for finishing adjustment holes on buckle-and-tongue belts; and a grooved burnisher tip with grooves of 3 different widths to finish belt edges, bag straps, shoes, saddles and holsters. HARDY TROPICAL SANDALWOOD does not heat too quickly when used at 10,000rpm or less. It allows Leather Burnisher Tips to deliver consistent edges across different thicknesses of leather. 1/8 DIAMETER METAL SHANKS are precision-set so there is no wobble during use. Built to endure the rotational stress supplied by motorized tools, these leather burnishers are a must-have addition to your leather working tools. These long-lasting leather burnishers are compatible with other rotary tools as well as with any other motorized tool that accepts metal shanks.
