Triumph Twist Drill 033324 3/8 in Hss Weldon Drill Bit

Product Description

The TRIUMPH TWIST DRILL 033324 is a 3/8-inch mechanics drill bit built for high-performance drilling in metal and alloy workpieces. Manufactured from high speed steel with an oxide finish, it features a Weldon shank with three flats for positive chuck engagement and reduced slippage under load. The split point geometry at 135 degrees initiates cutting without a center punch and reduces walking on hard surfaces. Web thinning further reduces thrust requirements, making this bit well suited for production and field drilling applications handled by machinists, millwrights, and maintenance mechanics.

This is a right-hand cut, regular-spiral, jobber-length drill bit from the T1M series. The 4-1/4-inch overall length and 2-11/16-inch flute length are standard jobber proportions, fitting a wide range of drill press, mag drill, and hand-drill applications in fabrication shops, mechanical rooms, and field service environments. Primary workpiece material is alloy, though the HSS construction handles a broad range of ferrous and non-ferrous metals at typical shop speeds. No coolant-through capability - conventional flood or mist cooling applies where required.

Key Features

• 135-degree split point starts on contact without center punching and reduces thrust
• Weldon shank with 3 flats prevents rotation in the chuck under heavy feed rates
• Web-thinned, parallel-web construction reduces cutting resistance and heat buildup
• High speed steel construction with oxide finish for improved lubricity and corrosion resistance
• Right-hand cut, regular spiral flute for standard metal drilling applications
• Jobber-length proportions fit standard drill chucks and mag drill adapters

Compatibility

Designed for use in Weldon-shank compatible drill chucks and mag drill arbors rated for 3/8-inch shanks. Suited for drilling alloy steel and similar ferrous workpieces in production and maintenance applications.

Installation Notes

Installation and use should be performed by qualified machinists or mechanics familiar with metalworking drill bit practices. Secure the Weldon shank fully in the chuck and tighten set screws against all available flats before operation. Power down and lock out the machine before changing bits. Apply cutting fluid or mist cooling as required by workpiece material and feed rate to extend tool life and maintain dimensional accuracy.
