The main body of our rhinestone is made of high quality high-speed steel, and the tool head is made of high quality diamond, both of which are laser welded. The outer wall adopts baking paint to prevent rust. The cutter head has flat teeth and wave teeth, which can meet different needs. Among them, the top edge of the wave teeth is sharper, the knife groove can be two-way water cooling, two-way chip removal, the wear resistance of the product is stronger, the drilling speed is faster and not easy to wear. The drill can be used with hand drill, charging drill, bench drill, angle grinder (need to be equipped with adapter). The tool head adopts the mechanism design, the drilling will not appear the wobble problem, the drilling is easier and effortless.

Note: If water is not added in the process of use, the drilling time should not be too long, and do not play high hardness, so as not to burn the product and damage the knife head and hurt people.

 

Wavy type teeth:Tooth top double groove wear-resistant, fast drilling speed, not easy to wear

Flat teeth:After a period of use, the teeth wear thin and the speed decreases

 

The handle is triangular. It can be more compatible with hand drill, power tools. Make the grip more firm and safe.

The main body of our rhinestone is made of high quality high-speed steel, and the tool head is made of high quality diamond, both of which are laser welded. The outer wall adopts baking paint to prevent rust. The body chip removal hole is extended and widened oval, which increases the chip removal function and heat dissipation function, so that the operation is more smooth. The diamond content of the tool head is increased by 30%, and the wear resistance of the tool head is stronger. Tool head adopts segmented design, cutting resistance is less, chip removal is more smooth, the opening is smooth and neat, no rough edge. The drill can be used with hand drill, charging drill, bench drill, angle grinder (need to be equipped with adapter). The tool head adopts the mechanism design, the drilling will not appear the wobble problem, the drilling is easier and effortless.

Note: If water is not added in the process of use, the drilling time should not be too long, and do not play high hardness, so as not to burn the product and damage the knife head and hurt people.
