5.7 Inch / 145mm Hole Saw Red with Arbor and Pilot Drill Bit, Bi-Metal Hole Cutter for Fiberboard, Wood, Drywall, Plastic, Soft Metal Sheet, PVC Board

5.7 Inch / 145mm Hole Saw Red with Arbor and Pilot Drill Bit, Bi-Metal Hole Cutter for Fiberboard, Wood, Drywall, Plastic, Soft Metal Sheet, PVC Board

Efficient Cutting Performance: made of high speed steel and high hardness alloy, the 5.7 inch bi-metal hole saw bit allows for smooth and precise cuts with minimal heat buildup, resulting in faster completion times and enhanced productivity Applicable to Standard Tools: Designed to fit standard hole saw arbors and mandrels, this sheet metal hole cutter is compatible with a wide range of drilling equipment, making it easy to integrate into existing tool setups and workflows for seamless operation Sharp and Durable: featuring a bi-metal construction, the hole drill bit is equipped with a clockwise forward gear mechanism and a centrally located spring-loaded drill bit, which facilitates efficient cutting and easy ejection of the cut material Compatible cutting material: the drill hole cutter is suitable for hole cutting of materials such as wood boards, gypsum boards, pilaster boards, fiberboards, plastic boards, and soft metal sheets. It is not applicable to fireproof boards, cement boards, glass, tiles, etc Please Note for Your Safety: the power tool adapter is screwed into the circle saw bit in a clockwise direction. Therefore, when making holes, please drill in a clockwise direction to avoid the connecting rod of the hole saw from unlocking and falling off due to counterclockwise rotation
