LD-157 Bi-Metal Hole Saw Kit 8 to 16 Piece | Wholesale Supplier

The LD-157 Bi-Metal Hole Saw Kit delivers professional-grade hole cutting performance for a wide range of construction, electrical, plumbing, and fabrication applications. Each hole saw features a bi-metal construction with a hardened high-speed steel (HSS) cutting edge electron-beam welded to a flexible carbon steel body. This combination provides the hardness needed to cut through wood, plastic, and thin sheet metal while the flexible body resists shattering if the saw binds or catches during cutting. Variable-pitch teeth reduce vibration and chip clogging for smoother, faster cutting with less user effort. The kit includes a universal arbor mandrel with hex shank for secure chuck grip, and two replaceable pilot bits with standard drill point for accurate centering and easy pilot hole starting. Three set configurations are available: the 8-piece set covers sizes from 16mm to 51mm for basic needs, the 11-piece set extends to 64mm for most general applications, and the 16-piece set provides the full range up to 89mm including hard-to-find large diameters. All components store neatly in a rugged blow-mold plastic case with individual compartments and a size identification guide molded into the lid for quick selection on the job site. Whether installing door locks, drilling electrical outlet boxes, cutting pipe access holes, boring wood panels, or creating HVAC duct openings, the LD-157 hole saw kit has the right size for every job.
