LD-185 Lock Installation Hole Saw Cutter Kit | Wholesale Supplier

The LD-185 Lock Installation Hole Saw Cutter Kit is a specialized door preparation toolkit designed for locksmiths, carpenters, door installers, and contractors who need to cut clean, accurate holes for lock hardware installation. The kit includes bi-metal hole saws with M3 high-speed steel cutting edges electron-beam welded to a flexible alloy steel backing, providing the sharpness to cut through wood, composite doors, and thin-gauge hollow metal doors while resisting tooth breakage. The 54mm diameter hole saw creates the main lock bore for standard cylindrical locks and deadbolts, while the 22mm and 25mm hole saws cut latch bolt holes and smaller hardware openings. Carbon steel spade bits in 16mm, 22mm, and 25mm sizes provide fast, economical hole cutting for latch faceplates and strike plate mortises. A 6mm HSS pilot drill ensures centered hole placement when used with the adjustable depth stop arbor, preventing the hole saw from wandering on the door surface. The arbor features a 7/16 inch hex shank that fits standard drill chucks and quick-change adapters. All components are organized in a blow-mold plastic case with custom-cut foam compartments that keep each tool secure during transport and prevent damage between jobs. Whether installing new locks in residential entry doors, replacing worn commercial door hardware, preparing doors in new construction, or performing locksmith service calls, the LD-185 hole saw cutter kit provides the precision cutting tools needed for professional door lock installation.
