Bi-Metal Hole Saw, 45Mm Industrial Grade Stainless Steel Tct Carbide, High Speed Steel Metal Alloy Hole Saw For Metal

【EXCELLENT MATERIAL】: The metal hole saw is made of high-quality TCT carbide and high-quality titanium coating After high-density grinding and high-end heat treatment. Effectively prevents corrosion and rust, with super heat resistance and longer service life. 【ULTRA HIGH PERFORMANCE】: Our metal hole saw adopts variable tooth technology Combined with the design of three-blade and front and rear inner, middle and outer inclination angles, the cutting resistance is small, the hole opening efficiency is high, no breakage occurs, and the cutting depth can reach 25 mm. 【ACCURATE HOLE OPENING】: The metal hole saw has a positioning aid and a triangular shank design This can help you position accurately and ensure that the drill hole does not slip or get stuck. Helps cut precise, clean, and burr-free holes for safer and more reliable drilling. 【CHIP REMOVAL DESIGN】: It adopts the discharge spring design The spring-loaded pilot drill automatically ejects the cutting block during cutting. A new and improved large chip removal groove is adopted on the side to ensure smooth chip removal during operation and effectively prevent chipping caused by chip blockage. 【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. soon. (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 + 1 x Hex Shank When machining stainless steel and steel sheets over 5mm, please add coolant or water. 2. When the cutting thickness exceeds 16mm, remove the ejector spring of the pilot drill. 3. Apply anti-rust oil to the product after use to extend its service life. 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. During the drilling operation of the drill, keep the drill and the workpiece vertical; 4. Use a small feed force when starting drilling, and use a medium feed force after positioning; 5. When drilling, the speed should not be too low to avoid 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 through the workpiece, the workpiece should be pulled out while the drill is rotated; 8. When drilling continuously, the cutting edge should be cooled with cutting fluid..
