Value Collection 01188481 No. 48 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188481 is a No. 48 wire-gauge jobber-length drill bit ground from high speed steel (HSS) with a black oxide coating. The bit measures 2 inches in overall length with a 1 inch flute length and a 0.0760 inch diameter. The 118-degree standard point angle makes this a general-purpose bit suited to drilling steel, cast iron, and similar ferrous materials in production or maintenance shop environments. Two regular spiral flutes evacuate chips efficiently, and a web-thinned, tapered web configuration reduces thrust requirements at the point. The straight cylindrical shank seats directly into standard drill chucks without adapters.

This jobber drill is a staple in metal fabrication shops, maintenance facilities, and trade service vans wherever small-diameter wire-size holes are needed. Typical applications include pilot holes, clearance holes for fasteners, and light-duty drilling in ferrous stock. The 0.0760 inch cutting diameter falls in the 0.0500 to 0.1000 inch size range, making it appropriate for precision sheet-metal work, conduit knockout preparation, and mechanical assembly tasks common to HVAC, plumbing, and electrical trades.

Key Features

• No. 48 wire size, 0.0760 inch cutting diameter for small-hole accuracy
• 118-degree standard point angle for general-purpose ferrous drilling
• High speed steel construction with black oxide finish for corrosion resistance and reduced friction
• Web-thinned tapered web reduces feed force and point walking
• Two regular spiral flutes for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill chuck accepting a 0.0760 inch straight shank. Primary workpiece materials listed by the manufacturer are steel and cast iron.

Installation Notes

This bit is installed by a machinist, maintenance technician, or trade professional using a hand drill, drill press, or similar machine tool. Secure the shank firmly in the chuck before operation and verify the work piece is clamped or fixtured to prevent rotation. Use cutting fluid or oil when drilling hardened steel or cast iron to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace if chipping or dulling is evident, as a worn 0.0760 inch bit can deflect and produce oversized holes.
