[1]APPLY TO - 4241 High Speed Steel Hole Saw is engineered for drilling thin materials(3mm or less), such as soft metals, wood, PVC and plastics, with specific compatibility for structural alloys like low-carbon steel, brass, and aluminum alloys. It operates effectively on hand-held electric drills, bench-mounted vertical drills, and portable magnetic base drills, serving critical functions in automotive maintenance, metal fabrication, and carpentry renovation projects [2]SPECIFICATION - Hole Saw Diameter: 19.5mm (25/32"), Cutting Depth: 3mm (0.12"), Shank Diameter: 7.5mm (0.3"), Total Length: 63mm (2.48") with Triangular Shank, with 1pc Center Drill Bit Diameter: 5mm (0.2"), with 1pc Hex Key [3]DESIGN - Surface Hardening Treatment (Nitriding + Titanium-Plated) - Provides the surface of the hole saw with high wear resistance, rust-resistant and aesthetically pleasing. [4]ADVANTAGES - Our hole saw are heat-treated + surface treatment (Quenched + Tempered) to increase hardness and red-hardness as well as wear resistance，extending service life and increasing machining efficiency [5]EXPAIN - Need to rotate the center drill to make it fixed, use the hex key to align the locking pin with the hole of the groove of the center drill, tighten and fix it on the tool could be used, at the same time, you need to pay attention to the installation of the spring. Pay attention to keep the vertical state APPLY TO
