Triumph Twist Drill 060413 13/64 Screw Machine Drill Bit

Product Description

The TRIUMPH TWIST DRILL 060413 is a screw machine length drill bit designed for heavy-duty drilling applications in demanding materials. Built from high speed steel with a coated finish, this bit measures 13/64 inch (0.2031 inches) in diameter and delivers reliable performance in tight-clearance, high-cycle environments. The 135-degree split point reduces walking on entry and lowers the thrust needed to start the cut. Web thinning further improves cutting efficiency, making this bit well suited for production drilling in superalloys and other difficult workpiece materials.

This drill bit is intended for use in screw machine operations and other short-hole drilling setups where a compact tool length is required. The T4HD series is built for heavy-duty industrial use, making it a practical choice for machinists and maintenance professionals working with hard or abrasion-resistant materials. Right-hand cut and regular spiral fluting support standard clockwise drilling operations with consistent chip evacuation throughout the flute length of 1.1875 inches.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with metal cutting operations. Secure the straight-cylindrical shank fully in a properly sized chuck or collet before operation. Ensure the spindle speed and feed rate are appropriate for the workpiece material before cutting. Inspect the cutting edge for wear or damage before each use and replace the bit if the point shows signs of chipping or dulling.
