Triumph Twist Drill 060410 Screw Machine Drill Bit 5/32

Product Description

The TRIUMPH TWIST DRILL 060410 is a screw machine length drill bit designed for heavy-duty drilling applications in tight, confined spaces where standard-length bits cannot reach or would flex under load. Built from high speed steel with a coated finish, this bit measures 5/32 inch (0.1562 inches) in diameter with a 135-degree split point that reduces walking on entry and requires less feed pressure. The overall length is 2-1/16 inches with a 1-inch spiral flute length. Right-hand cut with a tapered web and web-thinned geometry, the T4HD series is engineered for durability in demanding production environments. Licensed machinists, tool and die technicians, and industrial maintenance professionals are the primary users.

This drill bit is suited for screw machine operations and general drilling where a stubby, rigid cutting tool is required to minimize deflection. Its primary workpiece material rating is superalloy, making it appropriate for harder materials that demand a heavy-duty grade bit. The straight-cylindrical shank seats securely in standard drill chucks or quick-change holders on benchtop drill presses, CNC screw machines, and hand-held power drills. The regular spiral flute pattern promotes efficient chip evacuation during through-hole and blind-hole drilling in production and repair settings.

Key Features

• 5/32 inch (0.1562 inches) diameter in the T4HD heavy-duty series
• 135-degree split point reduces bit walking and lowers required feed force
• Web-thinned, tapered web construction for improved cutting efficiency in hard materials
• Screw machine length at 2-1/16 inches overall for rigid, low-deflection performance
• High speed steel construction with coated finish for extended wear resistance
• Right-hand cut with regular spiral flute for consistent chip removal

Compatibility

Designed as a heavy-duty screw machine length drill bit rated for superalloy workpiece materials, fitting standard drill chucks and quick-change tooling systems that accept straight-cylindrical shanks in the 5/32 inch diameter range.

Installation Notes

Secure the straight-cylindrical shank firmly in the drill chuck and verify runout before beginning a drilling cycle. Ensure the workpiece is clamped or fixtured to prevent movement under cutting forces. Coolant-through is not supported on this bit, so use an appropriate cutting fluid applied externally when drilling hard or abrasive materials. Follow applicable shop safety standards and machine guarding requirements during operation.
