Twister Bits come in two styles:

• Gold coated for all around rail drilling
• Black coated for better performance for fully heated rail.

Available in 3/4" thru 1-11/16" diameters. These cutters are backwards compatible. They can be used in older Trak-Star drills with their flatted areas on the shanks. Twister Arbor Systems are standard on all new Gas and Hydraulic Rail Drills. Retrofit Kits are also available for existing drills.

Pilots

Standard Twister Bit Pilot		Conversion Pilot
A pilot should always be used when cutting with Twister Bits. It provides two functions: One to release coolant to the cutter and two to eject the slug at the end of the hole.		The NorFast Conversion Pilot is used with 1-11/16" cutters. It can also be used for enlarging an existing hole.
