Bi-metal hole saw, 80 mm, TCT carbide, industrial-grade stainless steel. High-speed steel metal alloy hole saw for metal, aluminum alloy, plastic, and wood.

"

【ULTRA HIGH PERFORMANCE】: Our metal hole saw adopts variable tooth technology. Combined with the three-blade design (front and rear) with internal, middle, and external tilt angles, cutting resistance is low, hole opening efficiency is high, breakage is prevented, and the cutting depth can reach 25 mm.

【PRECISE HOLE OPENING】: The metal hole saw has a positioning aid and a triangular shank design. This helps you position it accurately and ensures the drill bit doesn't slip or get stuck. It 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 large chip removal groove An improved design 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 installations. It can be used with bench drills, magnetic drills, pistol drills, impact drills, etc. (Note: Cannot be used on concrete, tile, or stone)

Package Contents

: 1 x 80mm drill bit + 1 x Hex Shank. Usage Suggestions: 1. When machining steel sheets Stainless steel and steel thicker than 5 mm. Please add coolant or water. 2. When the cutting thickness exceeds 16 mm, remove the pilot drill's ejection spring. 3. Apply rust-preventative oil to the product after use to prolong its service life. Notice: 1. Check the drill's integrity before use. 2. When the drill is loaded into the electric drill, the three surfaces of the corresponding handle must be tightened. 3. During drilling, maintain the drill and workpiece vertically. 4. Use a small feed force when starting drilling and a medium feed force after positioning. 5. When drilling, the speed should not be too low to prevent the cutting edge from binding and causing the cutter to break. 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 The drill bit is drilled through the workpiece. The workpiece must be removed while the drill bit is rotating; 8. During continuous drilling, the cutting edge must be cooled with cutting fluid.
