With the advanced technology, and the alloy- cutter-head, which results in small cutting resistance and high opening efficiency during working process. Grinding center positioning drill, to accurately positioning before drilling, which ensure the accuracy, fast and efficient drilling during work. Optimizing the design of the chip removal groove to ensure smooth chip removal and effectively prevent debris blocking. The anti-slip triangle handle, holding firmly in working process, not easily to slip, enables safety and higher guarantee in working process.

TCT cemented carbide hole opener can drill holes on ordinary steel plate, alloy steel plate, stainless steel plate and cast iron. The cutting plate thickness is 5mm, and the cutting edge is made of high-quality tungsten, cobalt and vanadium alloy. It can cut all kinds of non-ferrous metals, black metals and non-metal, especially for cold and hot metal and stainless steel plate.

BOSENDA high quality TCT Hole Saws can be used for drilling on stainless steels, cast-irons, aluminum alloys and a various of non-standard metal materials.

Product specifications from 12-200MM, according to the processing materials and the product specifications, please choose the appropriate number of revolutions.

Precautions:
Check the integrity of the drilling hole before use;
Clamp the triangular surface when installing the drilling hole into the electric drill;
Keep the perpendicularity of the drilling hole and the working face when working;
Use a small force at the beginning of drilling, and then increase the force appropriately after positioning;
When working, the rotation should not be too slow to avoid the blade being stuck;
When the center drill is drilling into the object, it is not appropriate to use too much force in order to avoid the blade edge;
When drilling continuously, cold cutting fluid is suggested to be used.
