Chicago-latrobe 47254 Jobber Drill Bit 2.60mm Hss 118 Deg

Product Description

The CHICAGO-LATROBE 47254 is a high speed steel jobber-length drill bit designed for general-purpose metal drilling in production and maintenance environments. It carries a 118-degree standard point angle with web thinning for reduced thrust on entry, and a black oxide coating that provides light corrosion resistance and reduces friction during the cut. The straight cylindrical shank measures 0.1024 inches in diameter, compatible with standard three-jaw drill chucks. At 2.2441 inches overall length, this is a compact, rigid tool well suited to handheld drill motors, drill presses, and CNC machining centers operating in general metalworking applications.

This drill bit is sized at 2.60 mm (0.1024 inches) and falls within the DIN 338 standard for jobber-length twist drills. It is intended for drilling steel and cast iron in residential maintenance shops, commercial fabrication facilities, and light industrial settings. The two-flute regular spiral geometry handles chip evacuation efficiently in through-hole and blind-hole applications at typical hand-feed and machine-feed rates. HVAC technicians, pipefitters, electricians, and general maintenance mechanics commonly reach for jobber drills in this size range when drilling pilot holes, clearance holes, and anchor locations in steel structural members and enclosures.

Key Features

• 118-degree standard point angle with web-thinned tip reduces entry thrust on steel and cast iron
• Black oxide coating provides light lubricity and mild corrosion resistance during storage and cutting
• High speed steel construction withstands heat generated in general-purpose metal drilling without rapid edge breakdown
• DIN 338 jobber-length specification ensures dimensional consistency and interchangeability across tool systems
• Regular spiral two-flute design promotes efficient chip clearance in both through-hole and blind-hole drilling
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill conforming to DIN 338, sized for use in standard three-jaw drill chucks accepting straight shanks at 0.1024 inches diameter. Rated for primary use in steel and cast iron workpieces.

Installation Notes

Install the shank fully into the drill chuck and tighten securely before operation. Secure the workpiece with a vise or clamp before drilling to prevent movement and reduce the risk of injury. Use cutting fluid on steel workpieces to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed, as a damaged edge increases heat and can cause workpiece damage.
