Value Collection BS2700020 5/16 in Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS2700020 is a 5/16-inch high speed steel jobber drill bit designed for general-purpose drilling in production and maintenance applications. The 130-degree point angle delivers fast, positive engagement on entry. The slow spiral flute geometry promotes efficient chip evacuation and is well suited to aluminum and non-ferrous materials. Overall length is 4.5 inches with a flute length of 3.1875 inches. The bright, uncoated finish is standard for HSS tooling used in moderate-speed, general-purpose work. Two-flute construction balances chip clearance with wall support in the hole.

This jobber drill is intended for use on aluminum, brass, copper, plastics, and other non-ferrous workpiece materials in shop, field, and maintenance environments. The straight cylindrical shank accepts standard three-jaw drill chucks found on portable drills, drill presses, and lathes. The web-thinned, tapered web configuration reduces thrust required at entry and is particularly useful when drilling softer non-ferrous stock by hand-held power tools or bench machines. The bit conforms to ANSI specification designation standards for jobber-length drills.

Key Features

• 5/16-inch (0.3125 inch) diameter for precise fractional sizing
• 130-degree standard point angle for fast penetration and self-centering entry
• Slow spiral flute optimized for aluminum and non-ferrous chip flow
• High speed steel construction provides good wear resistance at moderate cutting speeds
• Web-thinned tapered web reduces thrust load at drill entry
• Bright uncoated finish — compatible with cutting oils and coolants applied externally
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose fractional jobber drill for use in standard three-jaw drill chucks across portable power drills, drill presses, and light CNC or manual lathes wherever a 5/16-inch straight-shank bit is required.

Installation Notes

Installation and use of drill bits should be performed by machinists, maintenance technicians, or tradespeople familiar with rotary cutting tools and safe machine operation. Always power down and lock out the machine spindle before inserting or removing the bit from the chuck. Secure the workpiece firmly in a vise or fixture before drilling to prevent rotation or grab. Apply appropriate cutting fluid or lubricant when drilling non-ferrous metals to extend tool life and improve hole finish.
