Value Collection BS38N0079 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION BS38N0079 is a taper length drill bit designed for precision drilling in metalworking and machining applications. Manufactured from high-speed steel (HSS) with a black oxide finish, this bit handles the tight tolerances required when working with small-diameter holes. The 0.0145-inch diameter corresponds to wire gauge size 79, making it the correct selection for instrument work, fine mechanical assemblies, and close-tolerance pilot holes. The 118-degree point angle is the standard geometry for general-purpose drilling across a wide range of materials. A tapered web configuration and web-thinned point reduce thrust and improve chip evacuation in small-diameter cuts. Licensed machinists, tool and die professionals, and production floor technicians are the primary users of this bit.

This drill bit is suited for general-purpose production and maintenance machining environments requiring wire-gauge-sized holes. The straight cylindrical shank seats in standard drill chucks on drill presses, CNC machining centers, and hand-held power drills. The taper length body provides additional reach compared to a jobber-length bit of the same diameter, making it useful in deeper-clearance drilling scenarios. The right-hand spiral flute design evacuates chips upward and out of the bore during standard clockwise rotation. No coolant-through capability is present, so external cutting fluid application is recommended when drilling steel or stainless alloys at this diameter.

Key Features

• Wire gauge size 79 — 0.0145 inch diameter for precision small-hole applications
• HSS construction provides hardness and wear resistance across ferrous and non-ferrous materials
• Black oxide finish reduces friction and provides mild corrosion resistance during storage and use
• 118-degree standard point angle suits general-purpose drilling in a broad range of substrates
• Tapered web with web-thinned point lowers thrust load and improves chip flow at small diameters
• Regular right-hand spiral flute with straight cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard three-jaw drill chucks and collet systems that accept straight cylindrical shanks at wire-gauge diameters.

Installation Notes

This bit is installed and removed by a qualified machinist or tool operator using a standard keyed or keyless drill chuck. Ensure the drilling machine is powered off and the spindle has come to a complete stop before changing bits. At 0.0145 inch diameter, bits are extremely fragile — use the lowest practical feed pressure and confirm the workpiece is rigidly clamped to prevent breakage. Apply cutting fluid externally when drilling steel or other hard alloys to extend tool life and prevent work hardening.
