Triumph Twist Drill 033308 1/8 Inch Hss Split Point Drill Bit

Product Description

The TRIUMPH TWIST DRILL 033308 is a 1/8 inch (0.1250 inch decimal) high speed steel jobber-length mechanics drill bit built for demanding trade and industrial applications. It features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch on most surfaces. The oxide finish provides light corrosion resistance and reduces friction during cutting. With a right-hand spiral flute and web-thinned construction, this bit clears chips efficiently and reduces thrust load. It is well suited for machinists, pipefitters, electricians, HVAC technicians, and maintenance professionals who drill alloy, steel, and similar ferrous materials regularly.

This bit is designed for jobber-length applications in hand drills, drill presses, and machine tool setups. The straight cylindrical shank fits standard 3-jaw chucks without adapters. The T1M series targets high-performance metal drilling in production and service environments. Primary workpiece material is alloy and similar metals. The parallel web configuration and regular spiral type make it a reliable general-purpose choice for repetitive hole-making tasks in trade shop and field service settings alike.

Key Features

• 135-degree split point self-centers and reduces walking without a center punch
• High speed steel construction handles alloy and ferrous workpiece materials
• Web-thinned design reduces thrust load and improves chip evacuation
• Oxide finish provides light corrosion resistance and friction reduction
• Straight cylindrical shank fits standard 3-jaw chucks directly
• Jobber length with 1-7/16 inch flute length suits a wide range of drilling depths

Compatibility

Designed as an OEM-style jobber drill bit for use in standard 3-jaw chuck hand drills, drill presses, and machine tool spindles accepting a straight cylindrical shank at 1/8 inch diameter.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling to prevent premature wear or bit breakage. Apply consistent feed pressure appropriate for the workpiece material and use cutting fluid on alloy and harder steels to extend bit life. Always wear appropriate eye protection when drilling. Disconnect or de-energize equipment before drilling into live panels or pressurized systems per applicable NEC or trade safety codes.
