Precision Twist Drill 5995608 Drill Bit Set 60 Pc

Product Description

The PRECISION TWIST DRILL 5995608 is a 60-piece screw machine length drill bit set designed for metalworking and general-purpose drilling applications. Built from high speed steel with a bright uncoated finish, these bits follow the Series R41 design and conform to ANSI specifications. The set covers wire gauge sizes from No. 60 through No. 1, giving machinists and maintenance technicians a full range of fractional-adjacent sizing without switching sets. All bits feature a standard 118-degree point angle and straight shanks, making them compatible with most drill presses, CNC machines, and hand drills used in machine shop and fabrication environments. The included metal storage case keeps the set organized and portable on the shop floor.

This set is suited for metalworking and multipurpose drilling tasks in both production and maintenance settings. The screw machine length format — shorter than jobber length — provides added rigidity and reduced deflection when drilling in tight clearances or on drill presses. It is a practical choice for machinists, tool-and-die technicians, and maintenance professionals who regularly require small-diameter wire gauge bits across a broad size range. General-purpose performance makes this set appropriate for steel, aluminum, brass, and similar materials at standard cutting speeds.

Key Features

• 60-piece set covering wire gauge sizes No. 1 through No. 60 in a single case
• High speed steel construction for general-purpose metalworking durability
• Screw machine length for increased rigidity and reduced deflection versus jobber-length bits
• Standard 118-degree point angle for broad material compatibility
• Bright uncoated finish — no coating to chip or flake during use
• ANSI-conforming Series R41 design with straight shanks
• Metal storage case included for organized, protected storage

Compatibility

Designed for use in standard drill presses, CNC drilling equipment, and handheld drills accepting straight shank bits across the wire gauge size range No. 1 through No. 60 in metalworking and multipurpose applications.

Installation Notes

Installation of drill bits should be performed by qualified machinists or maintenance technicians familiar with cutting tool practices. Ensure the drill chuck is fully tightened and the workpiece is properly secured before operation. Select appropriate spindle speed based on bit diameter and workpiece material per standard machining guidelines. Inspect each bit for damage before use and replace any bit showing chipping, cracking, or excessive wear.
