Glass drill ø12 (5901466176702)

This glass and ceramic drill bit is useful for a variety of finishing projects. It is used for creating countersinks and through holes in any glass, ceramic, and stoneware. The drill bit features a hexagonal shank that can be used in drills and screwdrivers. This ensures easy installation and replacement, and prevents the drill bit from slipping. The shank is heat-hardened, achieving a hardness of 30 HRC. This parameter reduces the risk of breakage and other mechanical damage. The working part is made of double-tipped tungsten carbide with a hardness of 89.5 HRC. This material produces holes quickly and precisely. The STALCO PERFECT range includes drill bits with blade diameters ranging from 4 to 12 millimeters. All are perfectly sharpened, ensuring precision and short drilling times.
