Osg 651018711 Carbide Jobber Drill Bit 3/16 in 140 Deg

Product Description

The OSG 651018711 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and difficult-to-machine materials. Sized at 3/16 inch (4.76 mm) diameter, it features a 140-degree drill point angle with an R-thinned web for improved self-centering and reduced thrust on entry. The EgiAs coating provides thermal and wear resistance suited to demanding production environments. With an overall length of 95 mm (3.74 inches) and a flute length of 44 mm (1.73 inches), this bit is configured for a 5xD flute-to-diameter ratio, making it appropriate for moderate-depth blind holes and through-hole applications. Installation is handled by machinists and CNC operators.

This drill bit is built for cutting steel, alloy steel, cast iron, titanium, and titanium alloys as designated by material codes P, K, S, and H. It is suited for blind hole drilling, cross hole operations, standard drilling, and self-centering entry without a center drill. The straight-cylindrical shank at 3/16 inch fits standard collets and chucks. Coolant-through capability supports chip evacuation and extended tool life in production runs where heat buildup and chip management are critical concerns.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating provides elevated heat and oxidation resistance during high-speed cutting
• 140-degree split point with R-thinned web for self-centering entry without pre-drilling
• Coolant-through design supports chip flushing in blind and cross-hole applications
• Right-hand spiral flute with regular helix and tapered web configuration
• Diameter tolerance held to +0 to -0.018 mm for consistent fit in close-tolerance holes

Compatibility

Designed for use in steel, alloy steel, cast iron, titanium, and titanium alloys (material codes P, K, S, and H). Suitable for CNC machining centers, drill presses, and any setup with a standard 3/16 inch straight-shank collet or chuck.

Installation Notes

This drill bit is installed and operated by machinists or CNC technicians. Ensure the machine spindle and workpiece are securely fixtured before operation. Verify coolant lines are active when using the coolant-through feature to prevent heat buildup and premature tool wear. Do not exceed the recommended speed and feed parameters for the workpiece material category being machined.
