Characteristics of rail bit

The general materials of rail drill are cemented carbide and high-speed steel series, which are used together with rail drill. The drill bit is welded with high-strength cemented carbide blades, which has the advantages of long drilling life, difficult wear of blades and difficult fracture of the drill bit, and can be ground many times after wear.

Rail drills are divided into high-speed steel series and cemented carbide series, which are used in conjunction with rail drills.

It is an essential drilling tool for railway maintenance. It is characterized by many cutting edges and good wear resistance.

The drilling accuracy is high, and the drilling efficiency is twice as high as that of ordinary twist drill. The drill bit is probably the hardest.

Drill 40-50 holes on the material track, and the drill bit can be ground continuously for more than ten times after being worn; Alternative

Carbide track drill, the drill bit is welded with high-strength carbide blades, and the drilling life is long.

Orbital bit

Blades should not be worn, drill bits should not be broken, etc. And it can be ground several times after wear.

I hope I can help you and adopt it.
