This 1-1/16” hollow (annular) Twister™ drill bit makes it versatile for drilling rail in maintenance-of-way applications. It is built from hi-speed steel with a titanium aluminum nitride coating, designed to maintain integrity and quality while drilling rail.
According to testing by the AAR, these drill bits maintain a temperature around the drilled hole that is only 35° F higher than ambient temperatures. Thanks to the unique design and construction of these drill bits from Trak-Star, you can reduce the risk of thermally activated embrittlement, which can lead to stress cracks and fractures.
Not only that, but the titanium and aluminum nitride coating (TiAIN) helps extend the life of the annular bit, providing you with reliable performance for a longer period. Enjoy superior cutting performance, durability, and ease-of-use during railroad maintenance and repairs with the 1-1/16” twister rail drill bit.
