Osg 650023311 Screw Machine Drill Bit 15/64 Solid Carbide

Product Description

The OSG 650023311 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from solid carbide with a coated finish, this bit measures 0.2344 inches (15/64 inch) in diameter and features a 140-degree drill point angle optimized for hard and abrasive materials. The right-hand spiral flute geometry with R-thinned web and tapered web configuration reduces thrust and improves chip evacuation. Coolant-through capability supports high-speed machining operations. This bit is installed and used by machinists, tool-and-die trades, and maintenance professionals working on precision drilling tasks.

The OSG 650023311 is built for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length format provides a compact, rigid profile suited for CNC machining centers, drill presses, and manual machines where stub-length stability is required. The 3xD flute-to-diameter ratio and regular spiral type make it well matched to through-hole and blind-hole operations in tough ferrous and non-ferrous materials. It is a single-piece unit packaged individually and is well suited to production and maintenance environments that require consistent, repeatable hole quality.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree split point angle reduces walking and lowers entry thrust
• R-thinned web with tapered web configuration improves chip flow and reduces heat buildup
• Coolant-through design supports high-speed and deep-hole drilling
• Right-hand cut with regular spiral flute for standard CNC and manual machine compatibility
• Straight-cylindrical shank fits standard drill chucks and collets without adaptation

Compatibility

Designed as an OEM-style screw machine length drill bit for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Part of the OSG Series 6500 high-performance solid carbide drill line.

Installation Notes

This drill bit is installed by machinists and tooling technicians in CNC machining centers, drill presses, or manual drill fixtures. Ensure the spindle and chuck or collet are clean and properly sized for a straight-cylindrical shank before seating the bit. Always confirm machine RPM and feed rate are appropriate for the workpiece material and bit diameter before initiating a cut. Coolant supply lines should be verified and active when using the coolant-through feature to prevent premature tool wear.
