Value Collection BS27N0059 No. 59 Jobber Drill Bit Hss

Product Description

The VALUE COLLECTION BS27N0059 is a wire-gauge jobber-length drill bit sized to No. 59 (0.0410 inches decimal), ground from high-speed steel (HSS) with a bright, uncoated finish. The 130-degree split-point geometry and web-thinned, tapered web reduce thrust on entry and help keep the bit from walking on startup. At 1.625 inches overall length with a 0.6875-inch flute length, this is a compact drill suited for tight-clearance drilling operations. The slow-spiral flute design promotes efficient chip evacuation when working in aluminum and other non-ferrous materials. Installation is performed by machinists, tool-and-die technicians, and general maintenance trades.

This drill bit is designed for use in aluminum and non-ferrous workpiece materials where a standard, general-purpose hole is required. The straight cylindrical shank accepts standard drill chucks on benchtop drill presses, handheld power drills, and CNC machine spindles within the appropriate collet or chuck capacity range. The right-hand cutting direction is standard for conventional drilling operations. Two flutes provide a balance of chip clearance and rigidity appropriate for the small diameter.

Key Features

• Wire size No. 59 — 0.0410-inch decimal diameter for precise small-hole drilling
• 130-degree point angle with web-thinned, tapered web reduces thrust and walking
• Slow-spiral flute geometry optimized for aluminum and non-ferrous materials
• High-speed steel (HSS) construction for general-purpose durability
• Bright, uncoated finish — no coating buildup to affect tolerance in critical fits
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collets accepting a 0.0410-inch straight shank, conforming to ANSI specification for wire-gauge drill bits in the 0.0000 to 0.0500-inch size range.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the shank fully in the chuck and verify concentricity before drilling. Power down and de-energize the machine spindle before changing bits. Use appropriate cutting fluid or dry-cutting technique per the workpiece material specification. Small-diameter HSS bits are brittle — avoid side-loading or flexing the bit during operation.
