Introduction and types of hole saws
Hole Saw Cuts very hard materials, including hardened steel, cast iron, bricks, etc. Carbon steel shaft with a pilot drill. A hole saw can be used with any professionally used power drill.
Bi-Metal Standard Hole Saw
Cuts all machinable metals including stainless steel, wood, nailed wood, plastics, synthetic glass, drywall, fiberboard and composite materials. The standard cutting depth is 1-1/2", and it can cut workpieces with a size of 2*4'S. It needs to be configured with an axis to operate.
Bi-Metal Hole Saw
Cuts all machinable metals including stainless steel, wood, nailed wood, plastic, synthetic glass, drywall, fiberboard and composite materials. The standard cutting depth is 1-1/2", which can cut workpieces with a size of 2*4'S. No additional shaft is required for operation.
Bi-Metal Deep Load Hole Saw
The range of applications is the same as for bimetal standard hole saws. But the cutting depth is larger, reaching 1-7/8". It also needs to configure the shaft to operate.
Tungsten Carbide Hole Saw
Cuts wood, plastic, aluminum, steel, synthetic glass, drywall, fiberboard, plaster, tile, and countertops without nails. Compared with bi-metal hole saws, it has a coarse pitch and is suitable for high-speed cutting of soft materials, but not suitable for cutting pipes. The standard depth of cut is 1-1/2". Shaft configuration is required for operation.
