Osg 10196005 Screw Machine Drill Bit 0.196in Cobalt Hss

Product Description

The OSG 10196005 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 heat and wear resistance are critical. It features a 130-degree drill point angle with R-thinned web geometry for reduced thrust and cleaner entry into workpieces. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles. At 3 inches overall length with a 1.19-inch flute length, this compact stub-style bit is well-suited for rigid setups and short-reach drilling operations. Machinists, toolroom technicians, and production operators are the primary users.

This drill bit is sized at 0.196 inches in diameter, corresponding to wire gauge size 9 and 4.98 millimeters. It is intended for drilling steel and alloy steel in production machining, fabrication shops, and screw machine operations. The screw machine length format reduces deflection compared to jobber-length bits, making it preferred for high-volume repetitive drilling cycles on manual mills, drill presses, and CNC equipment. The 3xD flute-to-diameter ratio supports chip clearance in short-depth through-holes.

Key Features

• Cobalt high speed steel construction for elevated heat resistance in ferrous metal drilling
• 130-degree drill point angle with R-thinned web reduces entry thrust and improves centering
• Coated finish extends tool life in continuous production use
• Right-hand cut with 2 regular spiral flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Screw machine length minimizes deflection in rigid, short-reach setups

Compatibility

Designed as a screw machine length replacement drill bit for applications requiring a 0.196-inch diameter, wire gauge size 9 cut in steel and alloy steel workpieces, within the OSG Series 1000 high-performance cobalt drill line.

Installation Notes

Installation is performed by machinists or toolroom personnel in a machine shop environment. Secure the straight-cylindrical shank fully in the drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. Power down or e-stop the machine before changing bits. Do not exceed the recommended feed and speed parameters for cobalt high speed steel in the workpiece material being drilled.
