Osg 10468805 Cobalt Hss Screw Machine Drill Bit 15/32

Product Description

The OSG 10468805 is a cobalt high speed steel screw machine length drill bit designed for high-performance drilling in steel and alloy steel. It measures 15/32 inch (0.4688 inches) in diameter with a 130-degree point angle and a standard two-flute spiral configuration. The shortened screw machine length body provides added rigidity in drill press, lathe, and CNC applications where stub-length tooling is preferred. Web thinning (R-Thinned) reduces thrust at entry and improves chip evacuation. This bit is installed by machinists, tool-and-die technicians, and maintenance professionals working with ferrous metals.

This drill bit is suited for production drilling in steel and alloy steel on drill presses, turret lathes, CNC machining centers, and manual mills. The screw machine length keeps the tool close to the spindle, reducing deflection during interrupted cuts or deep-hole starts. The straight-cylindrical shank fits standard drill chucks and collet systems without modification. It is part of OSG Series 1000 and carries a high-performance grade designation, making it appropriate for moderate to high-speed drilling cycles in job shop and production environments.

Key Features

• Cobalt high speed steel construction for heat and wear resistance in ferrous metal drilling
• 130-degree point angle with R-Thinned web reduces entry thrust and improves centering
• Screw machine (stub) length body increases rigidity and minimizes deflection
• Regular spiral, two-flute design promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Diameter tolerance of +0 to -0.027 mm for consistent hole sizing

Compatibility

Designed as an OEM-style replacement or direct application tool for screw machine length drilling operations in steel and alloy steel; fits any standard drill chuck or collet system accepting a straight-cylindrical shank in the 15/32 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and machine operation. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always wear appropriate eye protection and follow the machine manufacturer's RPM and feed rate guidelines for cobalt HSS tooling in ferrous materials. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
