Value Collection 01188598 No. 59 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188598 is a No. 59 wire-size jobber-length drill bit ground from high speed steel (HSS) with an oxide coating for added surface hardness and corrosion resistance. The 118-degree standard point angle suits general-purpose drilling in steel, cast iron, and similar ferrous materials. A regular spiral flute with a tapered, web-thinned web configuration promotes chip evacuation and reduces walking at entry. The straight cylindrical shank measures 0.0410 inches in diameter, matching the bit diameter for direct chuck mounting. Right-hand cutting direction is standard for conventional drilling operations. Overall length is 1.625 inches with a flute length of 0.6875 inches.

This bit is suited for production and maintenance drilling in metal fabrication shops, machine shops, and field service applications where small-diameter precision holes are required. Wire-size bits in this range are commonly used by machinists, tool-and-die tradespeople, and HVAC or electrical technicians drilling pilot holes, clearance holes, or tap-prep holes in light-gauge steel and cast iron components. The No. 59 size corresponds to 0.0410 inches decimal equivalent, placing it in the 0.0000 to 0.0500 inch drill bit size range.

Key Features

• No. 59 wire size, 0.0410 inches decimal equivalent diameter
• 118-degree standard point angle for general-purpose entry into ferrous materials
• High speed steel construction with oxide coating for surface protection
• Web-thinned, tapered web reduces thrust and improves chip flow
• Regular spiral flute with right-hand cutting direction
• Straight cylindrical shank for standard chuck compatibility

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks and drill presses accepting straight cylindrical shanks; primary workpiece materials are steel and cast iron.

Installation Notes

This bit is installed and operated by machinists and trade technicians using a drill press, hand drill, or CNC spindle with an appropriately sized collet or chuck. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the machine. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life. Wear eye protection and secure the workpiece before drilling.
