MASTER MECHANIC HOLE SAW, 2-1/8", BI-METAL, SPEED SLOT, ARBORED W/PILOT DRILL

Description: MASTER MECHANIC HOLE SAW, 2-1/8", BI-METAL, SPEED SLOT, ARBORED W/PILOT DRILL, MODEL 698835This bi-metal hole saw by Master Mechanic bores 2-1/8" diameter holes through a variety of materials: hardwoods, softwoods, plastics, drywall, cement board and fiberglass to name a few. Bi-metal means a very hard, high speed steel band is welded onto a high carbon steel body and thick, carbon steel backplate. While the primary use for this hole saw is to create holes for doorknobs on doors that aren't pre-drilled for door-knobs, it's not just limited to this one application. The high-speed cutting edge and variable tooth pattern reduce noise and vibration producing faster, smoother cuts. This hole saw can even bore through materials that have nails, pipes, stainless steel parts, rubber and conduit embedded in them. If you think you might be boring through something that contains a water line or electrical line, we highly recommend you turn off both your water and electrical mains prior to starting your journey to the center of the earth. Like most hole-saws, this one has a pilot drill to ensure proper alignment (so if you're a chiropractor, you'll really appreciate it). While technically a one-piece bit, the pilot drill bit can be detached from the mandrel and if you're really stuck, the mandrel can also be detached from the saw cylinder. The mandrel is a hex-head with the correct indentation for a speed-bit chuck / collet but will also work on drills with conventional chucks (though drill chuck needs to be able to accommodate a 3/8" bit). Hole saw can bore through material up to 1-7/8" thick. Not recommended for stone, marble or trepanning.
