Twister Bits™
Trak-Star Twister Bits™ are the standard tooling for drilling all types of rail. They are available in two different styles: Black coated M42 HSS and Carbide Tipped. Twister Black Bits are resharpenable, made in the USA and feature a Titanium Aluminum Nitride coating for extended tool life when cutting rail (up to 400 BHN). Carbide Twister Bits feature brazed in carbide tips and offer up to 2-1/2 times the tool life in both standard and extremely hard rail when used with the RB35.
The unique annular (hollow) design and thicker cutter wall offers extended tool life and extra durability. Twister Bits feature the quarter --turn style mounting for quick and easy installation with no tools required. When used with a Trak-Star Rail Drill, installation is simple; insert the bit into the arbor, and give it a turn.

Twister Bits can also be used with similar rail drilling systems with a 3/4" arbor bore. The shank of the bit features a flat that easily adapts to the set-screw style mounting, offering a secure installation, and allowing Trak-Star cutting technology to be used in multiple systems.
