Description
This 1-1/4” annular drill bit is manufactured by Trak-Star. It is built from an advanced M42 HSS steel with a titanium and aluminum nitrate coating (TiAIN). With this 1-1/4" Twister drill bit, you can create consistent holes in hardened rail steel, making it an excellent addition to your toolbox. Thanks to their unique design and powerful performance, these 1-1/4" Twister rail drill bits from Trak-Star are the industry standard for drilling all types of rail.
This drill bit is strong and durable, and has been tested by the AAR to help maintain rail temperatures when drilling. During testing, it was found that the surrounding area around the hole reached temperatures of 35° F above ambient temperatures, which helps reduce issues like stress cracks and thermally-induced embrittlement.
In addition, these 1-1/4” annular drill bits are built to last with a thick cutter wall, and are convenient and easy to use, with a quarter-turn mounting style for a quick and easy installation on all compatible rail drills.
