Drill Bit

Thermal Friction Drill Bit which is also called hot drill, has changed the traditional drilling and fastening process. It can make the previous processing problem – tapping and fastening of thin plates and tubes can be easily solved in a few seconds.

The drill bit of the hot melt drill is made of tungsten carbide material. After the most advanced heat treatment process, the drill bit can maintain high hardness and high wear resistance at a high temperature of 600 degrees and a high-speed rotation of 1500~3000 rpm, and can withstand vertical extrusion pressure.

Hot melt drills are made of wear-resistant and high-temperature-resistant carbide materials.

When the tool and the workpiece come into contact, the high rotation speed and appropriate axial thrust (feed force) cause severe friction between the drill bit and the metal, instantly reaching a temperature of 600 to 800°C.

The metal in the area near the drill bit rapidly softens. Axial pressure is continued to be applied, quickly extruding bosses and bushings that are about 3 to 5 times the thickness of the original plate on the upper and lower surfaces of the workpiece. The whole process only takes 2 to 6 seconds.
