This 1-3/8” annular drill bit by Trak-Star is designed for routine use in railroad rail drilling operations and is ideal for cutting through high hardness rail. It is compatible both with Trak-Star Hougen track drills and a wide variety of other drills used in the rail industry.
Twister™ drill bits use an annular design that enhances lubricant flow, which results in lower temperatures around the drilled hole, as well as reduced burring and metallic imperfections. AAR testing has showed that drilling with Twister™ bits raised the temperature of the rail by only 35° F above ambient temperatures.
Thanks to the heavy-duty steel used in the construction of these Twister Rail Drill Bits - 1-3/8" and a titanium and aluminum nitride coating, this allows for extended tool life and enhanced performance. Shop Industry-Railway Suppliers for all your hydraulic railroad tools & equipment needs.
