Triumph Twist Drill 060404 1/16 in Screw Machine Drill Bit

Product Description

The TRIUMPH TWIST DRILL 060404 is a screw machine length drill bit designed for heavy-duty drilling in demanding applications. Built from high speed steel with a coated finish, this bit measures 1/16 inch (0.0625 inches) in diameter and delivers reliable performance in tight-clearance drilling tasks. The 135-degree split point reduces walking and requires no center punch on most materials. A tapered web with web thinning reduces thrust and improves chip evacuation. At 1-5/8 inches overall length, this bit fits screw machine and short-hole drilling setups where standard jobber bits are too long. Licensed trade professionals and machining technicians rely on this series for precision work in superalloys and other demanding workpiece materials.

The 060404 is suited for production drilling, short-hole work, and applications where rigidity and minimal deflection matter. The screw machine length body provides greater rigidity than jobber-length bits, making it a practical choice for drill press work, CNC setups, and hand-held operations in confined spaces. The right-hand spiral flute and straight-cylindrical shank ensure compatibility with standard drill chucks and collet holders. The T4HD series is rated for heavy-duty use, particularly in superalloy workpieces where tool life and cutting stability are critical.

Key Features

• 1/16 inch (0.0625 inches) diameter for fine-diameter drilling
• 135-degree split point reduces bit walking and cutting thrust
• Web-thinned, tapered web construction improves chip flow and reduces heat buildup
• Screw machine length body provides greater rigidity than jobber-length bits
• High speed steel construction with coated finish for extended tool life
• Right-hand cut, regular spiral flute - compatible with standard chucks and collet systems

Compatibility

Designed for use with standard drill chucks and collet holders accepting straight-cylindrical shanks. The T4HD series is rated for drilling in superalloys and falls within the 0.0000 to 0.1000 inch drill bit size range for small-diameter tooling systems.

Installation Notes

This drill bit is installed and used by machinists, tool and die technicians, and trade professionals operating drill presses, lathes, or CNC equipment. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operating. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not feature coolant-through capability.
