Triumph Twist Drill 033310 5/32 in Hss Split Point Drill Bit

Product Description

The TRIUMPH TWIST DRILL 033310 is a 5/32-inch (0.1562-inch decimal) high speed steel mechanics drill bit built for professional-grade drilling applications. It features a 135-degree split point that reduces walking and cutting torque at the start of each hole, making it well suited for production work and precision drilling. The oxide finish provides a basic level of lubrication and surface protection. With a right-hand spiral flute and web-thinned construction, this jobber-length bit delivers consistent chip evacuation and reduced thrust in ferrous and alloy materials. Licensed tradespeople, machinists, and maintenance technicians are the primary users.

This bit is designed for drilling into alloy steel, ferrous metals, and similar workpiece materials in industrial maintenance, mechanical assembly, and fabrication settings. The straight-cylindrical shank fits standard three-jaw chucks on benchtop drill presses, hand-held power drills, and magnetic-base drills. The T1M series designation indicates a high-performance jobber configuration optimized for general-purpose drilling in shop and field environments. The parallel web configuration and regular spiral flute geometry maintain cutting efficiency across a range of material hardnesses.

Key Features

• 5/32-inch diameter with 0.1562-inch decimal equivalent for precise sizing
• 135-degree split point reduces drill walk and lowers required feed pressure
• High speed steel construction handles alloy and ferrous workpieces
• Web-thinned, parallel web geometry reduces axial thrust during cutting
• Oxide coating provides surface protection and light lubrication
• Right-hand cut with regular spiral flutes for efficient chip removal

Compatibility

Designed for use in standard three-jaw drill chucks accepting straight-cylindrical shanks. Suitable for drilling alloy steel, ferrous metals, and similar materials as stated in the T1M series jobber-length drill bit specification.

Installation Notes

This bit is installed by machinists, maintenance technicians, and qualified fabricators using standard drill chuck equipment. Secure the shank fully in the chuck and verify concentricity before beginning a cut. Use appropriate cutting fluid or coolant when drilling harder alloys to extend tool life. Wear appropriate eye protection and follow shop safety procedures when operating any rotary cutting tool.
