Value Collection 01188473 No. 47 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188473 is a wire gauge No. 47 jobber-length drill bit ground from high speed steel (HSS) and finished with a black oxide coating. At 0.0785 inches in diameter and 2 inches overall length, this bit is sized for tight-tolerance drilling in ferrous materials. The 118-degree standard point gives a self-centering entry suitable for general-purpose work, while the two-flute regular spiral geometry clears chips efficiently. The web-thinned, tapered web reduces cutting resistance and extends usable tool life in production and maintenance drilling applications. This bit is installed and used by machinists, HVAC technicians, plumbers, electricians, and other trades that drill into steel or cast iron during fabrication or service work.

This No. 47 jobber drill is suited for light-material drilling tasks where a small-diameter HSS bit is required. Typical applications include pilot holes, clearance holes for small fasteners, and precision holes in sheet metal, structural steel, and cast iron. The straight cylindrical shank seats in standard drill chucks without modification. Its general-purpose grade makes it a practical choice for both shop and field use where a compact, short-OAL bit is needed.

Key Features

• Wire gauge No. 47 diameter: 0.0785 inches for small-hole and pilot-hole work
• 118-degree standard point angle for self-centering entry on flat and curved surfaces
• High speed steel construction withstands heat generated during steel and cast iron drilling
• Black oxide coating reduces friction and provides light corrosion resistance during storage and use
• Web-thinned tapered web lowers thrust requirements and cutting resistance
• Right-hand cutting, regular spiral flute for efficient chip evacuation

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks accepting a 0.0785-inch straight cylindrical shank. Primary workpiece materials are steel and cast iron.

Installation Notes

Secure the straight shank firmly in a drill chuck before use and verify the chuck key is removed before powering the tool. Use cutting fluid or coolant appropriate for the workpiece material to prolong edge life when drilling steel or cast iron. Inspect the cutting edges for wear before each use; a dull bit increases heat and can cause workpiece damage or bit breakage. Drilling at the correct speed and feed for the diameter and material is critical to achieving a clean hole and maintaining tool life.
