Bi-metal hole saw, 45 mm, industrial grade stainless steel, TCT carbide, high-speed steel, metal alloy, for metal, aluminum alloy, plastic, wood

【EXCELLENT MATERIAL】: The Flintronic metal hole saw is made of high-quality TCT carbide with a high-quality titanium coating. It undergoes high-density grinding and premium heat treatment, effectively preventing corrosion and rust, and offers superior heat resistance and a longer lifespan.【ULTRA HIGH PERFORMANCE】: Our metal hole saw adopts variable-tooth technology. Combined with the three-blade design featuring internal, mid, and external tilt angles, as well as front and rear cutting angles, cutting resistance is low, hole opening efficiency is high, breakage is minimal, and the cutting depth can reach 25 mm.【PRECISE HOLE OPENING】: The Flintronic metal hole saw has a positioning aid and a triangular shank design. This helps you position the hole precisely and ensures it doesn't slip or get stuck. Helps cut precise, clean, and burr-free holes for safer and more reliable drilling. 【CHIP REMOVAL DESIGN】: It adopts a spring-loaded design. The spring-loaded pilot drill automatically ejects the cutting block during cutting. A new, larger, improved 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 decorating work and industrial installations. It can be used with bench drills, magnetic drills, pistol drills, impact drills, etc. (Note: Not suitable for use on concrete, tile, or 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 Usage Suggestions: 1. When machining stainless steel and steel sheets thicker than 5mm, please add coolant or water. 2. When the cutting thickness exceeds 16mm, remove the ejection spring from the pilot drill bit. 3. Apply rust-preventative oil to the product after use to prolong its service life. Notice: 1. Check the integrity of the drill bit before use. 2. When the drill bit is loaded into the power drill, the three surfaces of the corresponding handle must be tightened. 3. During drilling operations, maintain the drill bit and the workpiece vertically. Use a small feed force when starting drilling and a medium feed force after positioning; 5. During drilling, the speed should not be too low to prevent the cutter edge from binding and causing the cutter to collapse; 6. When the center drill bit enters the workpiece, the force should not be too great to avoid a violent collision between the blade and the workpiece; 7. Once the drill bit has passed through the workpiece, the workpiece should be removed while the drill bit is rotating; 8. During continuous drilling, the cutting edge should be cooled with cutting fluid.
