【ULTRA HIGH PERFORMANCE】: Our metal hole saw adopts variable tooth technology. Combined with the three-blade, front, and rear inclination angle design (inside, middle, and outside), 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 features 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 groove An improved chip removal system 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: Cannot be used on concrete, tile, or stone)

2. When loading the drill into the electric drill, the three surfaces of the corresponding handle must be tightened.

3. During drilling, maintain the verticality of the drill and the workpiece.

4. Use a low feed rate when starting drilling and a medium feed rate after positioning.

5. When drilling, the speed should not be too low. to prevent the knife edge from binding and causing the knife 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.
