5PCS 16/18.5/20/25/30mm(5/8" to 1-3/16") HSS Hole Saw Cutter, Drill Bit Hole Saw Set Door Hole Drilling Kit for Stainless Steel, Aluminum Alloy, Copper, Iron, Plastic and Wood(Ti-Plating)

Cutting edge strictly symmetrical: Surface anti-rust treatment, smoother drilling and chipping.beneficial and efficient cutting, avoid offset drilling. Big space for chip removal, big space for chip removal, the chip resistance is small, the chip discharge is smooth, the heat generated by the hole is small, and the drilling is reduced. Compare with ordinary hole cutter, The Metal Hole Saw Kit drilling is sharper and more wear-resistant. Because the center Drill contains cobalt and the grinding teeth are formed at one time Through professional heat treatment. Clear and compact thread clamping, the Hole Saw Kit for Metal can be grind smoothly with high-speed. The shape of the handle is professionally designed, so the clamping is more stable. Suitable for opening large diameter holes through iron, aluminum, alloy, wood and plastic. Perfect for installing locks, knobs in doors, desks and cabinets. Make work fast and easy.
