Osg 651065511 Solid Carbide Jobber Drill Bit 21/32 in

Product Description

The OSG 651065511 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It measures 21/32 inches (0.6563 inches decimal, 16.67 mm) in diameter with an overall length of 201 mm and a flute length of 134 mm. The 140-degree point angle with R-thinned web geometry improves self-centering and reduces thrust at entry. An EgiAs coating provides heat and wear resistance suited for high-speed cutting applications. This bit is built for professionals who need consistent, accurate holes in hard-to-machine workpieces without frequent tool changes.

This drill bit targets metalworking and machining applications where standard high-speed steel tooling falls short. It is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. Typical applications include blind holes, cross holes, general drilling, and self-centering entry cuts. The 5xD flute-to-diameter ratio makes it well-suited for moderate-depth holes in production and job-shop environments. Coolant-through capability supports both flood and through-spindle coolant delivery for extended tool life at elevated feeds and speeds.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating for improved heat resistance and extended tool life
• 140-degree point angle with R-thinned, tapered-web design for reduced entry thrust and self-centering
• Coolant-through design supports internal coolant delivery for deep-hole and high-speed applications
• Right-hand cut, regular spiral flute with straight-cylindrical shank at 3/4 inches shank diameter
• Diameter tolerance of +0 to -0.027 mm for consistent hole quality

Compatibility

The OSG 651065511 belongs to OSG Series 6510 and is designed for use in CNC machining centers and drill presses equipped with a straight-cylindrical shank toolholder sized for a 3/4 inches shank. It is rated for workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloys.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with carbide tooling. Before mounting, confirm the spindle and toolholder are clean and free of runout, as carbide is brittle and sensitive to lateral loading. Power down and lock out the machine before changing tooling. Do not use this bit in hand-held drilling applications — it is intended for rigid machine tool setups only.
