Value Collection BS27N0039 No 39 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0039 is a No. 39 wire-gauge jobber-length drill bit ground from high speed steel (HSS) with a bright, uncoated finish. The 130-degree split-point angle initiates cutting quickly and reduces walking on entry. A slow-spiral, two-flute geometry moves chips efficiently out of shallow holes while keeping the bit tracking straight. At 2.375 inches overall length with a 1.375-inch flute, this is a standard jobber format suited to hand drills, drill presses, and CNC machines running light-duty work. The straight cylindrical shank accepts standard three-jaw chucks without adapters. Installation and use require no special tooling beyond a properly sized chuck.

This bit is rated for aluminum and non-ferrous materials as the primary workpiece application. The slow spiral promotes clean chip evacuation in soft metals, plastics, and similar materials where aggressive helix angles can cause chatter or grabbing. The web-thinned, tapered-web point lowers thrust requirements, making it suitable for handheld operation in tight spaces or bench-drill work where feed pressure must stay controlled. It meets ANSI specification designation standards for jobber-length tooling. Sold individually, it fits general-purpose production and maintenance drilling tasks across HVAC, plumbing, electrical, and light fabrication trades.

Key Features

• No. 39 wire size, 0.0995 inch decimal diameter for precision small-hole drilling
• 130-degree point angle for fast penetration and reduced drill walk
• High speed steel construction handles repeated use in aluminum and non-ferrous metals
• Slow-spiral two-flute design promotes efficient chip clearing in soft materials
• Web-thinned tapered web lowers thrust and improves point stability
• Bright uncoated finish allows easy visual inspection of wear and edge condition

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 0.0995-inch straight cylindrical shank, including hand drills, drill presses, and CNC spindles configured for small-diameter tooling.

Installation Notes

A licensed technician or qualified tradesperson should secure the bit fully in a properly sized chuck before operation. Disconnect or de-energize all power to the drilling equipment before inserting or removing the bit. Do not exceed the drill speed recommended for the workpiece material and bit diameter. Wear appropriate eye protection and secure the workpiece firmly to prevent movement during drilling.
