Precision Twist Drill 5995677 Drill Bit Set 60 Pc

Product Description

The PRECISION TWIST DRILL 5995677 is a 60-piece screw machine length drill bit set built for metalworking and multipurpose drilling applications. Each bit is manufactured from high speed steel with an oxide finish and features a 135-degree split-point tip that reduces walking on contact and requires no center punch on most surfaces. The straight shank design is compatible with standard drill chucks. Wire gauge sizes run continuously from number 60 through number 1, giving technicians a complete range for tapping, clearance, and precision hole work in a single case. The set meets ANSI and NAS 907 specification requirements and is rated for heavy-duty performance.

This set is intended for metalworking professionals and multi-trade technicians who require a full wire gauge range on the job or at the bench. Screw machine length bits are shorter than jobber length, which increases rigidity and reduces deflection when drilling in metal, making them well suited for drill press work, CNC setups, and hand drilling in tight clearances. The included metal storage case keeps all 60 bits organized and protected between uses.

Key Features

Compatibility

Designed for use in standard straight-shank drill chucks across drill presses, CNC machines, and handheld drills used in metalworking and multipurpose drilling applications.

Installation Notes

Drill bit sets of this type are installed and serviced by machinists, HVAC technicians, plumbers, electricians, and general maintenance professionals. Secure the shank fully in the chuck and verify tightness before operation. Always wear appropriate eye protection when drilling metal. Follow applicable ANSI machine safety guidelines and ensure the workpiece is properly fixtured or clamped before drilling.
