Triumph Twist Drill 060418 Screw Machine Drill Bit 9/32

Product Description

The TRIUMPH TWIST DRILL 060418 is a screw machine length drill bit engineered for heavy-duty metal cutting in demanding industrial and trade applications. It features a 9/32 inch (0.2812 inch) diameter, a 135-degree split point for fast, accurate starts with minimal walking, and a right-hand spiral flute ground from high speed steel with a coated finish for extended tool life. The shortened screw machine length body provides greater rigidity than jobber-length bits, making it well suited for use in drill presses, CNC machines, turret lathes, and hand-held power tools where precise hole placement and reduced deflection matter. This bit is part of the T4HD series, which is designed for heavy-duty performance in difficult materials.

This bit is intended for drilling superalloys and other tough workpiece materials where rigidity and point geometry are critical. The screw machine length design is common in production machining environments, toolrooms, and maintenance shops. The straight-cylindrical shank accepts standard drill chucks without modification. The coated finish reduces friction and heat buildup during extended use. Machinists, tool-and-die workers, and maintenance technicians working in metalworking or industrial maintenance will find this bit appropriate for their standard drilling setups.

Key Features

• 9/32 inch (0.2812 inch) diameter, screw machine length for increased rigidity
• 135-degree split point reduces thrust and eliminates center-punch marking
• High speed steel construction with coated finish for durability and heat resistance
• Web-thinned, tapered web configuration reduces cutting resistance in tough materials
• Right-hand spiral flute with 1.5 inch flute length for efficient chip evacuation
• T4HD series heavy-duty grade rated for superalloy and hard-metal applications

Compatibility

Designed as a screw machine length replacement or production-use drill bit for standard drill chucks and toolholders accepting a straight-cylindrical shank in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with drill press, lathe, or CNC tooling setups. Secure the straight-cylindrical shank firmly in a calibrated drill chuck before operation and confirm runout is within acceptable tolerance for the application. Power down and de-energize the machine before changing tooling. Follow applicable shop safety procedures and manufacturer feeds-and-speeds guidelines for the workpiece material being drilled.
