Pilot Bit not included – Use with RRT-03635 Pilot Bit​


Trak-Star Twister Bits™ are the standard tooling for drilling all types of rail. 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 offer 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.

Twister Bits are easy to install
Just insert & twist!
