Value Collection 01189117 Letter K Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189117 is a letter-size K jobber-length drill bit designed for general-purpose metal drilling. Ground from high speed steel (HSS) with an oxide coating, it delivers reliable performance in ferrous materials including steel and cast iron. The 118-degree standard point angle suits a wide range of production and maintenance drilling tasks. At 4.25 inches overall length with a 2.9375-inch flute length, it fits standard drill chucks and drill presses used in fabrication, mechanical, and field-service work. The straight cylindrical shank measures 0.281 inches in diameter, matching the letter K decimal equivalent.

This bit is suited for drilling steel, cast iron, and similar ferrous workpiece materials in shop and field environments. The right-hand spiral flute geometry promotes chip evacuation in through-hole and blind-hole applications. The tapered web configuration with web thinning reduces thrust force at the cutting tip, which is useful when working in thicker stock. Two flutes provide a balance of chip clearance and cutting edge support appropriate for general-purpose production and maintenance drilling.

Key Features

• Letter K size — 0.281 inches decimal equivalent for precise hole sizing
• 118-degree standard point angle for general-purpose ferrous drilling
• High speed steel construction with oxide coating for wear resistance
• Web-thinned tapered web reduces cutting thrust on harder stock
• Right-hand regular spiral flute for efficient chip removal
• Straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks, drill presses, and hand drills accepting straight-shank bits with a 0.281-inch shank diameter. Primary workpiece materials are steel and cast iron.

Installation Notes

Installation and use of this drill bit is typically performed by machinists, maintenance mechanics, pipefitters, electricians, or HVAC technicians during fabrication or field service. Secure the straight shank fully in the chuck before operation and confirm chuck key removal before starting the spindle. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and improve hole finish. Wear appropriate eye protection per applicable shop safety standards.
