Hougen Manufacturing Inc./Trak-Star: Trak-Star® Drill Bits

Hougen Manufacturing Inc./Trak-Star

Trak-Star® Twister™ annular bits are designed to cut holes in rail in asfew as 15 seconds. They feature a quarter-turn style mounting for quick, easy, no-tools-required mounting in Trak-Star rail drills with Quick-Release Tool Mounting Arbors. They are precision-ground, premium high-speed steel with two coating options: Twister Gold Bits, Titanium Nitride coating; or Twister Black Bits, Titanium Aluminum Nitride coating for fully heat-treated rail (up to 400 BHN). AAR testing shows they restrict rail temperatures around the hole to just 35 F above ambient temperatures, eliminating thermally activated embrittlement, stress cracks and premature rail failure, the company says.
