Bi-metal Hole Saw, 45mm Industrial Grade Stainless Steel TCT Carbide, High Speed Steel Metal Alloy Hole Saw for Metal, Aluminum Alloy, Plastic, Wood

Description 【EXCELLENT MATERIAL】: The metal hole saw is made of high-quality TCT carbide and coated with high-quality titanium. After high-density grinding and high-end heat treatment, it effectively prevents corrosion and rust, with exceptional heat resistance and extended service life. 【ULTRA-HIGH PERFORMANCE】: Our metal hole saw adopts variable tooth technology. Thanks to the three-blade design, with inner, middle, and outer, as well as front and rear inclination angles, the cutting resistance is low, the hole opening efficiency is high, no breakage occurs, and the cutting depth can reach 25 mm. 【PRECISE HOLE OPENING】: The metal hole saw has a positioning aid and a triangular shank. This can help you position accurately and ensure that the drill hole does not slip or get stuck. Helps drill precise, clean, and burr-free holes for safer and more reliable drilling. 【CHIP REMOVAL DESIGN】: It adopts a discharge spring design. The spring-loaded pilot drill automatically ejects the cutting block during cutting. A new and improved wide chip removal groove is adopted on the side to ensure smooth chip removal during operation and effectively prevent chipping caused by chip jamming. 【WIDE APPLICATION】: This metal hole saw is widely used in interior decoration work and industrial facilities. Can be used for bench drills, magnetic drills, pistol drills, impact drills, etc. (Note: Cannot be used on concrete, tile, and stone) Material: TCT/Carbide Diameter: 45mm Shank Size: 10mm Cutting Depth: 25mm Color: Silver Package Contents: 1 x 45mm Drill Bit + 1 x Hex Shank Suggestions for Use: 1. When machining stainless steel and steel sheets over 5mm, please add coolant or water. 2. When the cutting thickness exceeds 16mm, remove the pilot drill ejector spring. 3. Apply anti-rust oil to the product after use to extend its service life. Note: 1. Check the integrity of the drill before use. 2. When the drill is loaded into the electric drill, the three surfaces of the corresponding handle must be clamped. 3. When drilling, keep the drill and the workpiece vertical. 4. Use a low feed force at the beginning of drilling and a medium feed force after positioning. 5. When drilling, the speed should not be too low to prevent the knife edge from getting stuck and causing the knife to collapse. 6. When the center drill enters the workpiece, the force should not be too large to avoid violent collision between the blade and the workpiece. 7. After the drill is drilled, withdraw it while rotating. 8. When drilling continuously, the cutting edge must be cooled with cutting fluid.
