Osg HP245-5118 Solid Carbide Jobber Drill 13mm 140 Deg

Product Description

The OSG HP245-5118 is a solid carbide jobber-length drill bit in the HP245 high-performance series, designed for demanding drilling applications in steel, alloy steel, and cast iron. The bit features a 13.00 mm diameter, a 140-degree R-thinned point angle, and a WD1 coating that extends tool life under high-load cutting conditions. The two-flute spiral geometry promotes efficient chip evacuation, while the straight-cylindrical shank provides consistent clamping in standard drill chucks and collet holders. This drill is suited for machinists, toolroom technicians, and CNC operators who require tight-tolerance hole quality in ferrous materials.

The HP245-5118 is built for production and job-shop environments where steel and cast iron are primary workpiece materials. Its 5xD flute-to-diameter ratio and R-thinned web thinning make it effective for blind hole drilling, cross-hole operations, general through-hole drilling, and self-centering applications. The tapered web configuration reduces thrust requirements at entry, improving process reliability on manual mills, machining centers, and drill presses. Right-hand cutting direction is standard.

Key Features

• Solid carbide construction for rigidity and heat resistance in ferrous materials
• 140-degree R-thinned point with tapered web for reduced thrust and accurate self-centering
• WD1 coating for enhanced wear resistance and extended tool life
• Two-flute regular spiral geometry for efficient chip evacuation
• 5xD flute-to-diameter ratio suitable for blind hole and cross-hole applications
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces with primary workpiece material codes P and K. Suited for use in blind hole, cross-hole, general drilling, and self-centering operations across the HP245 series application range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or CNC operators familiar with carbide tooling. Secure the shank fully in a collet or drill chuck rated for the shank diameter before operation, and verify spindle runout is within acceptable limits to avoid premature edge chipping. Carbide tooling is brittle — avoid impact loading, interrupted cuts without appropriate feed adjustments, or re-clamping a warm tool in a cold holder. Follow machine manufacturer guidelines and applicable shop safety protocols when setting speeds and feeds for the target workpiece material.
