Osg 10093805 Screw Machine Drill Bit 3/32 in Cobalt Hss

Product Description

The OSG 10093805 is a screw machine length drill bit designed for high-performance drilling in steel and alloy steel. It measures 3/32 inch (0.0938 inches) in diameter with a 130-degree split point and is manufactured from cobalt high speed steel for extended tool life in tough materials. The shortened screw machine length body reduces deflection and improves rigidity in close-quarters or turret applications. A two-flute spiral design with X-thinned web and tapered web configuration promotes efficient chip evacuation. Licensed machinists, tool-and-die shops, and maintenance professionals install this bit in drill presses, CNC turret lathes, and hand-held production drilling setups.

This bit is suited for production drilling and maintenance applications where precision hole sizing in steel and alloy steel is required. The screw machine length format makes it a practical choice for drill presses, turret lathes, CNC machining centers, and bench-mounted drilling fixtures where standard jobber-length bits create excess overhang. The straight cylindrical shank seats securely in standard three-jaw chucks and collet holders. Series 1000 from OSG targets high-performance cutting operations where tool durability and hole-size consistency are priorities across repeated drilling cycles.

Key Features

• Cobalt high speed steel construction for heat resistance and durability in ferrous materials
• 130-degree drill point angle with X-thinned web for reduced thrust and faster point engagement
• Two-flute regular spiral design for consistent chip evacuation in steel and alloy steel
• Screw machine (stub) length body reduces deflection and improves hole straightness
• Straight cylindrical shank compatible with standard chucks and collet toolholding systems
• Diameter tolerance of plus 0 to minus 0.014 mm for precise hole sizing

Compatibility

Designed as an OEM-style screw machine length drill bit for use in standard three-jaw chucks and collet holders across drill presses, CNC turret lathes, and production drilling fixtures. Primary workpiece materials are steel and alloy steel per OSG Series 1000 application guidelines.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle at a full stop. Secure the straight cylindrical shank fully into the chuck or collet to the recommended engagement depth before tightening. Verify spindle speed and feed rate are appropriate for the workpiece material and hole diameter before initiating the cut. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling deep holes or working in harder alloy steels.
