The hydraulic Trak-Star® RailMaster™ rail drill model RM42 is a power-feed unit designed to provide ease of drilling. The unit drills up to 1-1/2-inch diameter holes to 7/8-inch depth through fully heat-treated rail using Trak-Star Twister™ annular bits. The drill features Trak-Star Quick Release Tool Arbor and through-the-tool, pressurized coolant. The drill motor is powered from hydraulic pumps with 5 GPM and 2000PSI maximum capacity. The quick-connect hydraulic fittings and 10-point clamping system with high clamping forces are designed to make it fast and easy to position, set up and remove. At 48 pounds it is lightweight, highly maneuverable and portable, the company says.
