Osg 651034211 Carbide Jobber Drill Bit 11/32 in

Product Description

The OSG 651034211 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and hard metals. It measures 11/32 inches (0.3438 inches decimal) in diameter with a 140-degree R-thinned point that promotes self-centering and reduces thrust force on entry. The overall length is 128 millimeters with a 70-millimeter flute length. The EgiAs coating improves heat resistance and extends tool life in demanding applications. A straight-cylindrical shank of 3/8 inches fits standard drill chucks. This bit is suited for licensed machinists, toolroom technicians, and maintenance professionals working in production or job-shop environments.

The OSG 651034211 is built for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. Its 5xD flute-to-diameter ratio supports deeper blind-hole and through-hole work. It handles blind hole, cross hole, standard drilling, and self-centering operations. Coolant-through capability allows internal coolant delivery, making it a practical choice for CNC machining centers and production drilling where heat management is critical. The regular spiral and tapered web configuration maintain chip evacuation in interrupted and continuous cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating for thermal protection and extended tool life
• 140-degree R-thinned point for self-centering and reduced entry thrust
• Coolant-through design supports internal coolant delivery on compatible machines
• 5xD flute length ratio suitable for deeper blind-hole and cross-hole applications
• Right-hand cut with regular spiral and 2-flute geometry for efficient chip removal

Compatibility

The OSG 651034211 belongs to OSG Series 6510 and is rated for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloys (material codes P, K, S, H). It is designed for use in CNC machining centers and production drilling setups that support coolant-through tooling.

Installation Notes

Installation should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the 3/8-inch straight-cylindrical shank fully in a precision drill chuck or collet before operation. Carbide tooling is brittle compared to high-speed steel and should not be used in hand-held drills or unstable fixturing where lateral loading may cause fracture. Verify that the machine spindle and coolant system are fully operational and that workpiece clamping meets applicable shop safety standards before beginning the cut.
