Osg 630051111 Solid Carbide Screw Machine Drill Bit

Product Description

The OSG 630051111 is a solid carbide screw machine length drill bit engineered for high-performance drilling in ferrous materials. Measuring 0.5118 inches (13.00 mm) in diameter with a 140-degree split point, it is designed for fast, accurate hole-making in production and machining environments. The coated finish extends tool life by reducing friction and heat buildup during cutting. With a straight-cylindrical shank measuring 14.00 mm in diameter and an overall length of 107.00 mm (approximately 4.21 inches), this bit fits standard drill chucks used in CNC machining centers, drill presses, and manual lathes. Machinists, toolroom operators, and production line technicians are the primary users.

This drill bit is built for use in screw machine and general machining applications where stub-length rigidity is required. Its primary workpiece materials are steel, alloy steel, and cast iron — common in automotive, aerospace component, and general fabrication work. The 2xD flute-by-diameter ratio and R-thinned web configuration reduce thrust and improve chip evacuation in short, interrupted, or through-hole drilling operations. It is sold individually and is well suited to high-volume production environments where consistent hole diameter tolerances are critical.

Key Features

• Solid carbide construction provides rigidity and wear resistance in ferrous material drilling
• 140-degree drill point angle reduces thrust and improves self-centering on entry
• R-thinned web with tapered web configuration lowers cutting force and chip packing
• Coated finish extends tool life and reduces heat buildup at the cutting edge
• Right-hand spiral flute design promotes efficient chip evacuation in through and blind holes
• Screw machine length (stub) body increases rigidity and minimizes deflection in close-tolerance work

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces. Fits standard straight-cylindrical drill chucks accepting a 14.00 mm shank. Part of OSG Series 6300 high-performance solid carbide drill line.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a compatible drill chuck or collet to the recommended grip depth before operation. Ensure the machine spindle is fully stopped before inserting or removing the bit. Do not exceed the spindle speed and feed rate parameters established for solid carbide tooling in the workpiece material being drilled.
