Osg 8692480 Carbide Jobber Drill Bit 4.8mm 140 Deg

Product Description

The OSG 8692480 is a solid carbide jobber length drill bit engineered for high-performance drilling in ferrous and hard materials. It measures 4.8 mm in diameter with an overall length of 95 mm and a flute length of 44 mm. The 140-degree drill point with R-thinned web geometry reduces thrust and improves self-centering at entry. An EgiAs coating provides enhanced wear resistance and heat dissipation, extending tool life in demanding production environments. The 5.0 mm straight-cylindrical shank seats securely in standard collet chucks and drill chucks. This bit is suited for machinists, tool-and-die workers, and precision fabricators working in CNC or manual drilling operations.

The OSG 8692480 is designed for drilling in steel, alloy steel, cast iron, titanium, and titanium alloys — material codes P, K, S, and H. It handles blind hole, cross hole, through-hole, and self-centering drilling applications. The 5xD flute-to-diameter ratio makes it well suited for moderate-depth holes in a jobber length format. Coolant-through capability supports high-speed machining setups where internal coolant delivery is available, helping to clear chips and manage heat in tight-tolerance work.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for improved tool life and reduced heat buildup
• 140-degree drill point with R-thinned web for reduced entry thrust and self-centering
• Coolant-through design compatible with internal coolant spindle setups
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical 5.0 mm shank fits standard collet and drill chuck tooling

Compatibility

Designed for use in CNC machining centers, drill presses, and manual machines with collet or drill chuck tooling accepting a 5.0 mm straight shank. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloys (ISO material codes P, K, S, H).

Installation Notes

This drill bit is installed by qualified machinists or toolroom professionals. Secure the shank fully in the collet or chuck and verify runout before operation. Ensure the machine spindle is fully stopped before tool changes. When using coolant-through capability, confirm internal coolant pressure and flow rate are appropriate for the spindle and workpiece material before engaging the cut.
