RAIL DRILL – TWISTER BITS

TWISTER BITS (MADE IN USA)

Trak-Star Twister Bits™ are the standard tooling for drilling all
types of rail. They are available in two different styles: Black coated
DRILLS, SAWS & IMPACT WRENCHES
M42 Hss (High speed steel) and Carbide Tipped. Twister Black
Bits can be resharpened and feature a Titanium Aluminium 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 Trak-Star Model RB35 Petrol Rail Drill.

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 arbour and give it a turn.
Twister Bits can also be used with similar rail drilling systems with a 19.05mm (3/4”) arbour 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.
