Introduction to rail drill bits
Rail drill bits are also known as rail drill bits , hollow drill bit, core drill bit is a kind of cutting tool specially used for railway tracks.
A necessary drilling tool for railway maintenance and repair. Its characteristics include multiple cutting edges, good wear resistance, high drilling accuracy, and drilling efficiency that is doubled compared to ordinary twist drills. Rail drill bits/rail drill bits use a combination blade. The combination blade is composed of several outer blades, middle blades, and inner blades. Each blade only bears a small amount of work during the cutting process, and there is also a cutting knife on the inside of each blade. Therefore, chip removal can be very smooth. In addition, due to the characteristics of each cutting edge taking part of the cutting work, this hole drill is extremely unlikely to cause edge chipping.

Rail drill bit material:
Rail drill bits are generally made of carbide and high-speed steel series, which are used in conjunction with rail drilling machines. The drill bit is welded with a high-strength carbide blade. It has a long drilling life and is not suitable for blades. Wear drill bits are not suitable for breakage and can be repaired several times after wear.
Rail drill bits are divided into high-speed steel series and carbide series, which are used in conjunction with rail drilling machines
They are essential drilling tools for railway maintenance and repair. They feature multiple cutting edges and good wear resistance.
The drilling accuracy is high and the drilling efficiency is doubled compared to ordinary twist drills. One drill bit can drill holes in the hardest
rail material at one time, and the drill bit can be continuously ground more than ten times after wear. Another drill bit uses high-strength hard alloy steel rail drill bits. The alloy blade is welded and has a long drilling life. The blade is not suitable for wear and the drill bit is not suitable for breakage. It can also be sharpened several times after wear.
