Value Collection BS27N0073 No. 73 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0073 is a No. 73 wire-size jobber-length drill bit machined from high speed steel (HSS) with a bright, uncoated finish. It produces a 0.0240-inch diameter hole and features a 130-degree split point with web thinning to reduce walking and improve penetration on entry. The slow spiral flute design is optimized for chip evacuation in softer workpiece materials. At 1.125 inches overall length with a 0.3125-inch flute, this bit suits precision drilling tasks where a short, rigid tool is required. Licensed machinists, tool-and-die technicians, and production floor operators are the primary users.

This drill bit is rated for aluminum and non-ferrous materials as its primary workpiece application. The slow spiral geometry controls chip load and reduces heat buildup when cutting soft metals, plastics, and similar materials. The straight cylindrical shank at 0.0240 inches diameter is compatible with standard collets, Jacobs chucks, and precision drill press fixtures. It is well suited for small-diameter through-hole work on printed circuit boards, instrument panels, sheet metal components, and similar light-duty production applications.

Key Features

• No. 73 wire size with 0.0240-inch decimal diameter for precision small-hole work
• 130-degree split point with web thinning minimizes walking on entry without a center punch
• Slow spiral flute promotes clean chip evacuation in aluminum and non-ferrous materials
• High speed steel construction provides adequate heat resistance for general-purpose drilling
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Two-flute, right-hand cutting configuration compatible with standard rotating chuck setups

Compatibility

Designed as a general-purpose replacement or stock drill bit for use with standard straight-shank drill chucks, collets, and precision drill press fixtures accepting a 0.0240-inch shank diameter.

Installation Notes

Installation and use should follow standard machining safety practices. Secure the workpiece firmly before drilling to prevent rotation or shift. Ensure the chuck is tightened fully and the shank is fully seated before operation. At this diameter, excessive feed pressure can deflect or snap the bit — use light, consistent feed pressure appropriate for small-diameter HSS tooling.
