Value Collection BS27N0008 No. 8 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0008 is a high speed steel (HSS) jobber-length drill bit in No. 8 wire size, equivalent to 0.1990 inches in diameter. Designed for general-purpose drilling, it features a 130-degree split-style point angle and a slow spiral flute geometry that promotes efficient chip evacuation in softer workpiece materials. The bright, uncoated finish is well suited for drilling aluminum and other non-ferrous metals where coating adhesion or heat buildup is not a primary concern. Machinists, maintenance technicians, and fabricators will find this drill bit a reliable everyday tool for light production and maintenance drilling operations.

This drill bit is intended for use in aluminum, brass, copper, plastics, and other non-ferrous materials. The slow spiral flute reduces the tendency for the bit to grab or chatter in soft metals, making it a practical choice for hand-held drilling operations as well as drill press work. With a straight cylindrical shank at 0.1990 inches in diameter, it seats securely in standard three-jaw chucks. The 2.4375-inch flute length provides adequate chip clearance for through-hole drilling in typical workpiece thicknesses.

Key Features

• No. 8 wire size — 0.1990 inches diameter, straight cylindrical shank
• 130-degree point angle for reduced thrust and self-centering entry
• Slow spiral flute geometry optimized for aluminum and non-ferrous workpiece materials
• High speed steel construction for general-purpose durability
• Bright, uncoated finish — no coating to chip or delaminate in light-duty use
• Web-thinned, tapered web configuration reduces cutting resistance

Compatibility

Designed as a general-purpose jobber drill bit for use in any standard drill chuck accepting a 0.1990-inch straight shank, including hand drills, drill presses, and milling machine quills.

Installation Notes

This drill bit is installed and removed by a licensed machinist or qualified tradesperson using a standard three-jaw drill chuck key. Ensure the machine is fully powered down and the spindle has stopped completely before changing tooling. Secure the workpiece firmly with a clamp or vise before drilling to prevent rotation or movement. Do not exceed the rated speed range for the workpiece material and bit diameter, and use appropriate cutting fluid when drilling non-ferrous metals to extend tool life.
