Value Collection KP65113 Letter L Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION KP65113 is a letter-size L jobber-length drill bit designed for general-purpose drilling in steel and cast iron. It is manufactured from high speed steel (HSS) with an oxide coating that reduces friction and helps extend tool life under typical shop conditions. The 118-degree standard point angle is the most common geometry for drilling into ferrous metals. At 4.25 inches overall length with a 2.9375-inch flute length, it fits standard drill chucks and drill presses used daily by machinists, maintenance technicians, and fabricators.

This drill bit is suited for production and maintenance drilling in metalworking environments, including job shops, manufacturing floors, and mechanical maintenance applications. The straight cylindrical shank accepts three-jaw chucks on handheld drills, drill presses, and milling machines. The right-hand spiral flute evacuates chips efficiently when drilling steel plate, structural sections, and cast iron components. The web-thinned, tapered web configuration reduces the thrust required to start and advance the cut.

Key Features

• Letter L size (0.2900 inches decimal) for applications requiring a specific clearance or tap-drill diameter
• 118-degree standard point angle optimized for ferrous metals including steel and cast iron
• High speed steel construction withstands heat generated during continuous drilling cycles
• Oxide coating reduces friction and provides basic corrosion resistance during storage and use
• Web-thinned tapered web lowers thrust and improves chip clearance at the cutting tip
• Right-hand regular spiral flute for consistent chip evacuation in through-hole and blind-hole operations

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard three-jaw drill chucks accepting a 0.2900-inch straight cylindrical shank. Suitable for drilling steel and cast iron workpieces across a decimal inch size range of 0.2500 to 0.3000 inches.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the shank fully in the chuck before operation and verify chuck key removal prior to starting the spindle. Work should be clamped or fixtured to prevent rotation during drilling. Cutting fluid or coolant is recommended when drilling steel to extend bit life, even though this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
