Triumph Twist Drill 033307 7/64 in Hss Split Point Drill Bit

Product Description

The TRIUMPH TWIST DRILL 033307 is a 7/64 inch (0.1094 inch decimal) high speed steel jobber-length drill bit designed for precision metal drilling in trade and industrial applications. Built with a 135-degree split point, it starts on contact without walking, reducing the need for a center punch on most workpieces. The oxide finish provides basic lubricity and surface protection. The straight-cylindrical shank seats securely in standard drill chucks, and the web-thinned, parallel web construction reduces thrust and improves chip evacuation during drilling.

The 033307 is suited for drilling alloy steel, mild steel, and similar ferrous workpieces in mechanical, fabrication, and maintenance applications. The T1M series jobber-length geometry provides a balance of reach and rigidity for general-purpose hole-making. This bit is a common tool for machinists, maintenance mechanics, pipefitters, and millwrights working with ferrous metals in shop and field environments. The right-hand spiral flute design is compatible with standard right-hand drill presses, hand drills, and magnetic drills.

Key Features

• 7/64 inch diameter (0.1094 inch decimal) for precise sizing in close-tolerance applications
• 135-degree split point starts on contact and reduces center-punch requirements
• High speed steel construction handles ferrous metals and general alloy materials
• Web-thinned parallel web reduces drilling thrust and improves chip clearance
• Oxide finish provides surface lubricity and basic corrosion resistance
• Jobber length (T1M series) balances reach and rigidity for versatile use

Compatibility

Designed as an OEM-style replacement or standard stock drill bit for use in right-hand rotating drill presses, hand drills, and magnetic drills accepting straight-cylindrical shank tooling. Primary workpiece material compatibility is alloy and ferrous metals as stated by the manufacturer.

Installation Notes

Install and remove drill bits only with the drill fully powered down and the chuck key removed from the chuck. Seat the straight-cylindrical shank fully and evenly in the chuck before tightening. Use appropriate cutting fluid when drilling hard alloys to extend tool life and maintain hole quality. Inspect the split point for chipping or wear before each use; a damaged point reduces accuracy and increases thrust force.
