Osg 10332005 Screw Machine Drill Bit 0.332in Cobalt Hss

Product Description

The OSG 10332005 is a screw machine length drill bit designed for high-performance drilling in steel and alloy steel applications. Built from cobalt high speed steel with a coated finish, this bit handles demanding production environments where standard HSS tooling falls short. The 130-degree split point promotes accurate starting and reduces thrust force on tough ferrous materials. At 0.332 inches (letter size Q) in diameter and 3.5 inches overall length, it fits standard drill chucks and machine tool spindles used in screw machine, CNC, and bench drilling operations. Licensed machinists and tool-room technicians are the primary users of this tooling.

This drill bit is suited for production drilling in steel and alloy steel workpieces. The screw machine length format — shorter than jobber length — provides added rigidity in CNC machining centers, turret lathes, and screw machine setups where chatter and deflection must be controlled. The 1.688-inch flute length accommodates typical hole depths in these applications. The straight-cylindrical shank fits standard Jacobs-style and collet-type drill chucks without modification.

Key Features

• Cobalt high speed steel construction for heat resistance in steel and alloy steel drilling
• 130-degree drill point angle for fast penetration and accurate self-starting
• R-thinned web reduces thrust and improves chip evacuation
• Regular spiral flute with tapered web configuration maintains rigidity along the cutting zone
• Screw machine length body (3xD flute-to-diameter ratio) minimizes deflection in rigid setups
• Coated finish extends tool life in repetitive production drilling cycles

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for production machining and tool-room applications requiring a 0.332-inch diameter screw machine length drill in straight-cylindrical shank format.

Installation Notes

Installation is performed by machinists and tool-room technicians in production or maintenance settings. Secure the straight-cylindrical shank fully in the drill chuck or collet before operation, ensuring runout is within acceptable limits for the application. Always power down and lock out the machine before changing tooling. Follow the machine manufacturer's recommended speeds and feeds for cobalt HSS tooling in the workpiece material being drilled.
