Value Collection 01167550 No 55 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01167550 is a No. 55 wire-size jobber-length drill bit ground from high speed steel (HSS) with a bright, uncoated finish. It carries a 118-degree standard point angle and a web-thinned, tapered-web geometry that reduces thrust on entry. The straight cylindrical shank measures 0.0520 inches in diameter, matching the 0.0520-inch decimal drill size. Overall length is 1.875 inches with a flute length of 0.875 inches. Two regular spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling. This is a general-purpose jobber drill suited for production and maintenance work performed by machinists, tool-and-die techs, and sheet-metal fabricators.

The 01167550 is rated for aluminum and non-ferrous workpiece materials, making it a practical choice for drilling copper, brass, soft alloys, and similar materials in light manufacturing, electrical panel work, and HVAC sheet-metal fabrication. The small wire-gauge diameter and jobber-length proportions fit standard Jacobs-style drill chucks and precision pin vises. Coolant-through is not supported. The bright finish is appropriate for dry or lightly lubricated cutting operations where surface adhesion to the workpiece is not a concern.

Key Features

• No. 55 wire size, 0.0520 inches decimal diameter for precise small-hole work
• 118-degree standard point angle with web-thinned, tapered-web tip to reduce entry thrust
• High speed steel construction for general-purpose durability across non-ferrous materials
• Bright uncoated finish suitable for dry or lightly lubricated cutting
• Two regular spiral flutes for consistent chip evacuation in through and blind holes
• Right-hand cutting direction, straight cylindrical shank for broad chuck compatibility

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and pin vises accepting a 0.0520-inch straight shank, targeting aluminum and non-ferrous workpiece materials.

Installation Notes

This drill bit is installed and used by machinists, electricians, and sheet-metal workers using a drill press, hand drill, or rotary tool fitted with an appropriate chuck. Secure the shank fully in the chuck before operation and verify concentricity to avoid wandering on small-diameter holes. Use a center punch mark or a pilot hole to locate the entry point accurately on hard or smooth surfaces. Apply a light cutting fluid or lubricant when drilling copper or brass to extend bit life and improve hole finish.
