Bi-metal Hole Saw, 45 mm, Industrial Grade, Stainless Steel, TCT Carbide, High Speed Steel and Alloy Hole Saw for Metal, Aluminum Alloy, Plastic, Wood

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

【ULTRA HIGH PERFORMANCE】: Our metal hole saw features variable tooth technology. Combined with the design of the inner, middle, and outer three blades and the front and rear tilt angles, the cutting resistance is low, the hole opening efficiency is high, there is no breakage, and the cutting depth can reach 25 mm.</

【PRECISE HOLE OPENING】: The metal hole saw features a positioning aid and a triangular shaft design. This can help you position yourself accurately and ensure that the drilled hole does not slip or jam. Helps cut precise, clean, and burr-free holes for safer and more reliable drilling.

【CHIP REMOVAL DESIGN】: Relief spring design. The spring-loaded pilot drill automatically ejects the cutting block during cutting. A new and improved large chip removal groove is designed 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 equipment. Can be used for bench drills, magnetic drills, pistol drills, impact drills, etc. (Note: Cannot be used on concrete, tiles, and stone)

Suggestions for use:

1. When machining stainless steel and steel sheets larger than 5 mm, please add coolant or water.

2. If the cutting thickness exceeds 16 mm, remove the ejector spring of the pilot drill.

3. Apply anti-rust oil to the product after use to extend its service life.

Note:

1. Check the integrity of the drill bit before use.

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

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

4. Use a small feed force at the beginning of drilling, and a medium feed force after positioning;

5. When drilling, the speed should not be too low to avoid jamming the knife edge and causing the knife to collapse;

6. When the center drill penetrates the workpiece, the force should not be too large to avoid a violent collision between the blade and the workpiece.

7. Once the drill bit has drilled through the workpiece, the workpiece must be pulled out while rotating the drill bit;

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