Bi-metal hole saw, 48 mm TCT carbide in industrial-grade stainless steel, high-speed steel metal alloy core drill for metal, aluminum alloy, and plastic

• [EXCELLENT MATERIAL]: The MINKUROW 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. This effectively prevents corrosion and rust, offering superior heat resistance and a longer lifespan.
• [ULTRA HIGH PERFORMANCE]: Our metal hole saw features variable tooth technology.

• [PRECISION HOLE OPENING]: The MINKUROW metal hole saw has a positioning aid and a triangular shank design. This helps you position yourself 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, 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: Cannot be used on concrete, tile, or stone)

Usage Suggestions:
1. When machining stainless steel and steel sheets thicker than 5 mm, please add coolant or water.
2. When the cutting thickness exceeds 16 mm, remove the ejection spring from the pilot drill.
3. Apply rust-preventative oil to the product after use to prolong its service life.

Notice:
1. Check the integrity of the drill before use.
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 small 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 cutting edge from binding and causing the cutter to break;
6. When the central 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.
