Bi-Metal Hole Saw, 42mm Industrial Grade Stainless Steel TCT Carbide, High Speed ​​Steel Metal Alloy Hole Saw for Metal, Aluminum Alloy, Plastic, Wood

Bi-metal Hole Saw, 42mm Industrial Grade Stainless Steel TCT Carbide, High Speed Steel Metal Alloy Hole Saw for Metal, Aluminum Alloy, Plastic, Wood

【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. Effectively prevent corrosion and rust, with super heat resistance and longer service life.

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

【ACCURATE HOLE OPENING】: The metal hole saw has positioning aid and triangular shank design. This can help you position yourself accurately and ensure that the drill hole does not slip or get stuck. Helps cut precise, clean, burr-free holes for safer, more reliable drilling.

【CHIP REMOVAL DESIGN】: It adopts discharge spring design. Spring-loaded pilot bit automatically ejects the cutting block while cutting. A new upgraded large chip removal groove is adopted on the side to ensure smooth chip removal during operation and effectively prevent chipping caused by chip blocking.

【WIDE APPLICATION】: This metal hole saw is widely used in interior decoration work and industrial plants. Can be used for bench drills, magnetic drills, pistol drills, impact drills, etc. Soon. (Note: cannot be used on concrete, tile and stone)

Suggestions for use:

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

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

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

Notice:

1. Check the integrity of the drill before use.

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

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

4. Use a small feed force when starting drilling and use a medium feed force after positioning;

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

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

7. Once the bit is drilled through the workpiece, the workpiece must be pulled out while the bit is turned;

8. When drilling continuously, the cutting edge should be cooled with cutting fluid.
