Value Collection 01189125 Letter L Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189125 is a letter-size L jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. Built from high speed steel (HSS) with an oxide coating for improved wear resistance, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and helps center the bit on entry. The two-flute regular spiral design clears chips efficiently during through-hole and blind-hole operations. At 0.2900 inches in diameter, it fits standard drill chucks and is sized for applications requiring a letter L bore.

This bit is suited for maintenance, fabrication, and production drilling in residential and commercial trade settings. Typical applications include drilling pilot holes, clearance holes, and through-holes in structural steel, cast iron components, and similar workpieces. The straight cylindrical shank seats securely in three-jaw chucks on handheld drills, drill presses, and CNC drilling equipment. Right-hand cutting direction is standard for conventional clockwise-rotation machines. The 2.9375-inch flute length accommodates moderate drilling depths without excessive bit deflection.

Key Features

• Letter L size: 0.2900 inches diameter for precise bore sizing
• 118-degree standard point angle for general-purpose entry into ferrous metals
• High speed steel construction with oxide coating for wear and heat resistance
• Web-thinned tapered web reduces drilling thrust and improves centering
• Regular spiral two-flute design promotes efficient chip evacuation
• Straight cylindrical shank compatible with standard three-jaw drill chucks

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard three-jaw chucks on handheld drills, drill presses, and CNC drilling machines requiring a 0.2900-inch straight-shank bit. Rated for primary use in steel and cast iron workpieces.

Installation Notes

Secure the shank fully in the chuck and verify the bit runs true before beginning a cut. Power down and de-energize the drill press or disconnect the handheld tool before changing bits. Use appropriate cutting fluid or coolant when drilling steel to extend bit life, unless the machine setup prohibits it. Follow applicable shop safety standards and wear eye protection during all drilling operations.
