Carbide-Tipped and Heavy-Duty (Bi-Metal) Hole Saws
For Cutting Holes 1-1/8" Deep

Carbide-Tipped Heavy Duty
(Bi-Metal)
FIG 8797

Milford Tungsten Carbide-Tipped Hole Saws are designed to handle especially tough abrasive materials such as formica, fiberglass, tile,
bronze, copper and masonite. Tungsten carbide tips are fusion-welded to an alloy steel back to withstand the punishing heat and abra-
sion generated by these materials. The Heavy-Duty (Bi-Metal) Hole Saws are a high-speed steel cutting edge that is electron-beam weld-
ed to a tough alloy back, to cut clean, accurate holes in virtually any machinable material. Knockout holes allow easy removal of cores.
