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

Description

【EXCELLENT MATERIAL】: The metal hole saw is made of high-quality TCT carbide and coated with high-quality titanium. After high-density grinding and high-end heat treatment, it effectively prevents corrosion and rust, offering exceptional heat resistance and a long service life.

【ULTRA-HIGH PERFORMANCE】: Our metal hole saw adopts variable tooth technology. Thanks to the three-blade design, with internal, central, and external tilt angles, as well as front and rear 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 features a positioning aid and a triangular shank.

This can help you position the drill bit precisely and ensure it doesn't slip or bind. It helps drill accurate, clean, and burr-free holes for safer and more reliable drilling. 【CHIP REMOVAL DESIGN】: It features a spring-loaded design. The spring-loaded pilot drill automatically ejects the cutting block during cutting. A new, wide, and improved chip removal groove on the side ensures smooth chip removal during operation and effectively prevents chipping caused by chip blockage. 【WIDE APPLICATION】: This metal hole saw is widely used in interior decorating and industrial installations. It can be used with bench drills, magnetic drills, pistol drills, impact drills, and more. (Note: Not suitable for use 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 ejector spring from the pilot drill bit.

3. Apply rust-preventative oil to the product after use to prolong its lifespan.

Note:

1. Check the drill bit for damage before use.

2. When the drill bit is loaded into the power drill, all three surfaces of the corresponding handle must be tightened.

3. When drilling, keep the drill bit and the workpiece vertical.

4. Use a low feed rate at the beginning of 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 collapsing.

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 completed its rotation, remove it.

8. During continuous drilling, the cutting edge must be cooled with cutting fluid.
