Glass drill bit set STALCO PERFECT S-72182

A set of glass drill bits should be a part of every professional's toolkit. It's essential for glasswork, tiling, fabrication, and specialized repairs. The set includes five drill bits with diameters ranging from 4 to 10 millimeters. All are packaged in a plastic case, ensuring they won't get lost in a workshop or toolbox. The heat-treated shanks provide excellent resistance to breakage and deformation. The working part is made of double-tipped tungsten carbide with a hardness of 89.5 HRC. The drill bit features a hexagonal shank that fits into drills and screwdrivers, preventing the bit from spinning spontaneously in the chuck. The highly sharp tip ensures precise drilling with clean edges.
