Drilling bit for plastic plate drill hole

Abstract

The invention relates to a drilling bit for a plastic plate drill hole. The drilling bit for the plastic plate drill hole comprises a straight handle. A clamp head is installed at the upper end of the straight handle. The diameter of the clamp head is less than the diameter of the straight handle. A round barrel is fixedly connected with the bottom of the straight handle in a vertical mode. The round barrel and the straight handle are coaxial. The round barrel is in a hollow structure, the upper end of the round barrel is sealed through a sealing plate, an opening is formed in the lower end of the barrel, the bottom of the opening is a flush circumference, and the whole circumference is polished into a circular blade. In hole processing, the whole plastic plate receives force evenly and not prone to damaging, and cost is reduced.

Description

technical field [0001] The invention belongs to a processing machine, in particular to a drilling bit, especially for drilling plastic plates. Background technique [0002] With the development of society, plastic board has become a material with a wide range of uses, but to process it, the force should not be too large and the speed should not be too fast, especially for hole processing, because the bottom of the drill bit is not flat, forming a force Uneven, it is easy to damage the plastic board. The invention processes the bottom of the drill bit evenly, and when the hole is processed, the entire plastic plate bears uniform force, is not easy to be damaged, and reduces the cost. Contents of the invention [0003] The object of the present invention is to provide a drill bit for drilling plastic plates, which processes the bottom of the drill bit into a flat opening, and when processing holes, the entire plastic plate is evenly stressed, is not easily damaged, and redu...
