Osg 10113005 Screw Machine Drill Bit Size 33 Cobalt Hss

Product Description

The OSG 10113005 is a screw machine length drill bit designed for high-performance drilling in steel and alloy steel applications. Built from cobalt high speed steel and finished with a titanium nitride (TiN) coating, this bit handles demanding production environments where heat resistance and edge retention matter. It cuts at wire gauge size 33, equivalent to 0.1130 inches (2.87 mm), with a 130-degree split point that reduces walking and requires no center punch on most workpieces. The X-thinned web and tapered web configuration lower thrust requirements and improve chip evacuation. At 2-5/16 inches overall length, this screw machine length format fits standard drill chucks and close-clearance setups where a jobber-length bit is too long.

This drill bit is suited for CNC machining centers, drill presses, and handheld power tools in production and maintenance environments. It performs best in steel and alloy steel at feeds and speeds appropriate for cobalt HSS tooling. The screw machine length body provides rigidity in short-reach applications, making it a common choice for sheet metal fabrication shops, machine shops, and industrial maintenance crews working with ferrous materials.

Key Features

• Cobalt high speed steel construction for improved heat and wear resistance over standard HSS
• Titanium nitride (TiN) coating reduces friction and extends cutting life
• 130-degree standard point angle with X-thinned web for reduced thrust and improved centering
• Right-hand cut, straight-cylindrical shank fits standard drill chucks without adapters
• Screw machine length (3xD flute-to-diameter ratio) provides rigidity in tight clearance setups
• 2-flute spiral design with regular spiral type for efficient chip removal in ferrous materials

Compatibility

Designed for drilling steel and alloy steel workpieces. The straight-cylindrical shank at 0.1875 inches diameter fits standard drill chucks across CNC machining centers, drill presses, and handheld power tools. Part of the OSG Series 1000 screw machine length drill line.

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator. Secure the shank fully in the drill chuck and verify runout before cutting. Follow the machine manufacturer and OSG tooling guidelines for appropriate spindle speed and feed rate for the workpiece material. Do not exceed the rated cutting parameters for cobalt HSS tooling, and allow adequate chip clearance to prevent flute packing in deep-hole applications.
