Triumph Twist Drill 090522 60 Pc Jobber Drill Bit Set

Product Description

The TRIUMPH TWIST DRILL 090522 is a 60-piece jobber length drill bit set covering wire gauge sizes 1 through 60. Each bit is machined from high-speed steel (HSS) with a bright, uncoated finish and a 118-degree split point. The split point geometry reduces walking at the start of a cut and requires less feed pressure than a standard chisel point. These straight-shank bits fit standard drill chucks and are sized for inch-system metalworking applications. The set ships in a metal storage case that keeps bits organized and protects cutting edges between uses. Machinists, maintenance techs, and fabricators will find the full wire-gauge range useful for precision hole sizing and tap drilling.

This set is designed for general-purpose metalworking and multipurpose drilling tasks in industrial, commercial, and shop environments. The complete wire gauge range from 1 to 60 makes it a practical bench reference for drilling clearance holes, pilot holes, and tap-drill holes across a wide range of fastener and thread sizes. The jobber length format provides the standard flute-to-shank ratio most commonly used in drill presses, hand drills, and milling machine setups. It is well suited for maintenance shops, tool rooms, and fabrication environments where multiple bit sizes are needed on a regular basis.

Key Features

• 60-piece set covering wire gauge sizes 1 through 60 in a single metal storage case
• High-speed steel construction for general-purpose metalworking durability
• 118-degree split point reduces bit walking and lowers feed force required at entry
• Bright, uncoated finish - compatible with cutting fluids and coolants
• Straight shank fits standard drill chucks without adapters
• Jobber length format suits drill presses, hand drills, and milling setups

Compatibility

Designed for use in standard drill chucks accepting straight-shank jobber length bits in inch-system sizing. Suitable for general metalworking, maintenance, and fabrication applications requiring wire gauge drill sizes.

Installation Notes

Install and remove bits only with the drill or press fully powered off and the chuck key removed from the chuck. Select the correct bit size using a wire gauge reference chart before drilling to avoid enlarging holes. Use appropriate cutting fluid for the material being drilled to extend bit life. Dispose of worn or chipped bits rather than resharpening if split point geometry cannot be restored accurately.
