Triumph Twist Drill 011001 Drill Bit 1/64 in Hss Jobber

Product Description

The TRIUMPH TWIST DRILL 011001 is a 1/64 inch (0.0156 inch decimal) high speed steel mechanics drill bit designed for general-purpose drilling in a range of materials. Built to Series T1 jobber-length specifications, it features a standard 118-degree point angle, a right-hand spiral flute, and a bright uncoated finish. The straight-cylindrical shank seats directly in standard drill chucks. With an overall length of 3/4 inch and a 3/16 inch flute length, this bit is sized for precision small-diameter work in metalworking, woodworking, and light fabrication applications. Installation and use require no special adapters or collets.

This drill bit is suited for use on aluminum, aluminum alloy, bronze, and wood. Its jobber-length body and tapered web configuration make it appropriate for through-hole and pilot-hole drilling in bench-top and handheld drill applications. The web-thinned geometry reduces entry force on softer workpiece materials. It is a common tool in HVAC, plumbing, and electrical trade shops for small-diameter pilot work and sheet penetration tasks where precision entry is required.

Key Features

• 118-degree standard point angle for general-purpose drilling
• High speed steel construction for durability across a range of workpiece materials
• Straight-cylindrical shank for direct chuck mounting without adapters
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Web-thinned, tapered web geometry reduces drilling resistance on entry
• Bright uncoated finish; no coolant-through feature required for intended applications

Compatibility

Designed for use in standard drill chucks accepting straight-cylindrical shanks; suitable for drilling aluminum, aluminum alloy, bronze, and wood workpieces in general-purpose shop and field applications.

Installation Notes

This bit is installed by a machinist, fabricator, or trade technician using any standard keyed or keyless drill chuck sized to accept a 1/64 inch straight shank. Secure the shank fully in the chuck before operation and confirm the bit runs true before contact with the workpiece. Use appropriate RPM for the workpiece material and bit diameter; small-diameter bits are susceptible to breakage from side loading or excessive feed pressure. Eye protection is required during all drilling operations.
