Value Collection BS260000O Jobber Drill Bit Letter O Hss

Product Description

The VALUE COLLECTION BS260000O is a Letter O jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel (HSS) with a bright, uncoated finish, this bit features a 140-degree split point with web thinning to reduce walking and lower thrust requirements at the start of a hole. The fast spiral flute design promotes efficient chip evacuation during drilling. At 4.5 inches overall length with a 3.1875-inch flute length, this is a standard jobber geometry suited for use in hand drills, drill presses, and CNC drilling operations. The straight cylindrical shank measures 0.3160 inches in diameter for direct chuck mounting.

This drill bit is suited for drilling into steel, aluminum, other non-ferrous metals, and wood. Its Letter O size corresponds to a decimal diameter of 0.3160 inches, making it a go-to choice when a specific undersized hole is needed prior to reaming or tapping, or when a non-standard decimal diameter is required. The right-hand cutting direction and fast spiral configuration make it appropriate for production environments and maintenance shops handling varied material stock. Machinists, tool-and-die technicians, maintenance mechanics, and general fabricators are the typical end users.

Key Features

• Letter O size: 0.3160-inch decimal diameter for precise hole sizing
• 140-degree point angle with web thinning reduces walking and entry thrust
• High speed steel construction provides durability across ferrous and non-ferrous materials
• Fast spiral flute promotes chip clearance and reduces heat buildup in the cut zone
• Bright, uncoated finish allows visual inspection of wear and edge condition
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose replacement or stock jobber drill bit compatible with standard 3-jaw drill chucks accepting straight-shank bits up to 0.3160 inches in diameter, including hand drills, bench drill presses, and CNC drilling spindles.

Installation Notes

Install and remove this bit only when the drill or machine spindle is fully powered down and the chuck is stationary. Secure the shank fully within the chuck jaws and tighten with a chuck key before operation. Operators should use appropriate cutting fluid or coolant when drilling steel to extend edge life, even though the bit does not include internal coolant-through capability. Eye protection and secure workpiece fixturing are standard requirements under OSHA and shop safety practices.
