Value Collection 01167584 No 58 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01167584 is a No. 58 wire-size jobber-length drill bit machined from high speed steel (HSS) with a bright, uncoated finish. It carries a 118-degree standard point angle and a right-hand cutting direction, making it a general-purpose drilling tool suited for light-duty precision work. The bit measures 1.625 inches overall length with an 0.6875-inch flute length, and the decimal diameter is 0.0420 inches. A tapered web with web thinning reduces thrust and helps the point self-center on entry. Two regular spiral flutes clear chips efficiently during through-hole operations.

This bit is sized for small-diameter work in aluminum, non-ferrous metals, and similar soft materials. Typical applications include pilot holes, locating holes, and precision through-holes in sheet stock, tubing, and machined components. The straight cylindrical shank seats in standard drill chucks, collets, and CNC tool holders that accept the 0.0420-inch shank diameter. Machinists, maintenance technicians, and fabricators reach for this size when working on small fastener clearances, wire routing holes, or instrument panels where tight dimensional tolerances are required.

Key Features

• No. 58 wire size at 0.0420 inches decimal diameter for tight-tolerance small-hole work
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction provides adequate hardness for aluminum and non-ferrous workpieces
• Bright uncoated finish maintains close diameter tolerances straight from the manufacturer grind
• Right-hand cut with regular spiral flutes for consistent chip evacuation
• Straight cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as a general-purpose jobber drill bit for use in handheld drills, benchtop drill presses, and CNC machining centers equipped with chucks or collets that accept a 0.0420-inch straight shank. Primary workpiece material rating covers aluminum and non-ferrous metals.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the shank fully in the chuck or collet before operation and verify runout before drilling at speed. Ensure the workpiece is clamped or fixtured to prevent movement during the cut. At this diameter, use a center punch or spotting drill to establish a starting point and prevent bit walk. Do not apply excessive feed pressure, as small-diameter HSS bits are susceptible to breakage if deflected or forced.
