Osg 630021711 7/32 Inch Carbide Screw Machine Drill Bit

Product Description

The OSG 630021711 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from solid carbide, it delivers the rigidity and wear resistance needed when cutting steel, alloy steel, and cast iron. The bit measures 0.2188 inches (7/32 inch) in diameter with a 140-degree split point angle and an R-thinned web for reduced thrust and cleaner entry. At 66 millimeters overall length and a 2xD flute-to-diameter ratio, this stub-length geometry provides excellent stability in CNC and manual drilling operations where rigidity and hole accuracy are critical.

This drill bit is suited for production and maintenance environments that require consistent, repeatable hole quality in ferrous metals. The screw machine length format makes it a standard choice for drill presses, CNC machining centers, and turret lathes where a shorter cutting tool reduces deflection and improves positional accuracy. Machinists and tool-and-die professionals working with steel and cast iron components will find this bit appropriate for through-hole and blind-hole work in the 0.2000 to 0.2500 inch diameter range.

Key Features

• Solid carbide construction for hardness and long tool life in ferrous materials
• 140-degree drill point angle reduces entry thrust and improves chip formation
• R-thinned web with tapered web configuration minimizes walking and centering error
• Regular spiral flute with 2-flute design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet systems without modification
• Series 6300 high-performance designation for rigorous production and machining environments

Compatibility

Designed for use in steel, alloy steel, and cast iron workpieces. Fits standard drill chucks and collet holders accepting a straight-cylindrical shank in the 7/32 inch diameter range. Suitable for CNC machining centers, drill presses, and turret lathes within the 0.2000 to 0.2500 inch drill bit size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool handling and machine tool operation. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the bit from the chuck or collet. Solid carbide tooling is brittle and should not be subjected to side loads, interrupted cuts without proper feed rates, or drops onto hard surfaces. Follow the machine manufacturer and tooling supplier guidelines for speed and feed parameters appropriate to the workpiece material.
