Triumph Twist Drill 060432 Screw Machine Drill Bit 0.5in

Product Description

The TRIUMPH TWIST DRILL 060432 is a screw machine length drill bit designed for heavy-duty metal cutting in production and maintenance environments. Built from high speed steel (HSS) with a coated finish, this 0.5 inch diameter bit features a 135-degree split point that reduces walking and requires no center punch on most materials. The spiral flute design promotes chip evacuation, and the web-thinned, tapered web construction reduces cutting resistance. At 3.75 inches overall length with a 2.25 inch flute length, this stub-length bit provides increased rigidity compared to jobber-length alternatives. Licensed HVAC techs, machinists, and maintenance professionals working with tough ferrous materials will find this bit suited to demanding production drilling tasks.

The 060432 is engineered for drilling precipitation-hardened steels and superalloys, making it appropriate for aerospace, industrial maintenance, and fabrication applications where standard drill bits deflect or wear prematurely. The screw machine length keeps the bit short and stiff, which is especially useful in drill presses, CNC turret machines, and hand-held drill motors in tight quarters. The straight-cylindrical shank fits standard three-jaw drill chucks without adapters.

Key Features

• 0.5 inch diameter with 135-degree split point for fast, accurate starts on hard materials
• High speed steel construction with coated finish for extended tool life in ferrous metals
• Screw machine (stub) length at 3.75 inches overall for maximum rigidity and reduced deflection
• Web-thinned, tapered web reduces thrust and cutting resistance in tough alloys
• Right-hand spiral flute promotes efficient chip clearing during deep passes
• Series T4HD heavy-duty grade rated for PH steel and superalloy workpieces

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for any application requiring a 0.5 inch diameter, screw machine length, straight-shank HSS drill bit. Rated for primary workpiece materials including precipitation-hardened steel and superalloys per Series T4HD specifications.

Installation Notes

This bit is installed and used by machinists, tool-and-die workers, and maintenance technicians operating drill presses, lathes, or CNC turret equipment. Secure the straight-cylindrical shank fully into the chuck jaws before beginning any operation. Always power down and lock out equipment before changing bits. Use appropriate cutting fluid or coolant when drilling PH steels and superalloys to manage heat buildup and extend tool life.
