Osg 10147005 Cobalt Hss Screw Machine Drill Bit 0.147 in

Product Description

The OSG 10147005 is a cobalt high speed steel screw machine length drill bit designed for high-performance drilling in steel and alloy steel workpieces. It measures 0.147 inches in diameter (Wire Size 26, 3.73 mm) with a 130-degree split point and a straight-cylindrical shank. The screw machine length format provides a short, rigid profile that reduces deflection and improves hole location accuracy. With a 2-flute spiral configuration and X-thinned web, this bit delivers clean entry and efficient chip evacuation in production and maintenance drilling applications. Licensed trades and metalworking shops rely on this geometry for consistent performance in tight-tolerance work.

This drill bit is suited for use in CNC machining centers, drill presses, and hand-held power drills where a stub-length bit is preferred for rigidity. Primary target materials are steel and alloy steel. The screw machine (stub) length makes it a practical choice for confined drilling locations or applications where a standard-length bit would introduce chatter or walkoff. It is sold individually and is compatible with standard drill chucks accepting straight cylindrical shanks.

Key Features

• Cobalt high speed steel construction for elevated heat and wear resistance in steel drilling
• 130-degree point angle with X-thinned web for positive engagement and reduced thrust
• Screw machine (stub) length profile increases rigidity and minimizes deflection
• 2-flute spiral design promotes efficient chip removal
• Straight-cylindrical shank fits standard keyed and keyless drill chucks
• Tapered web configuration enhances core strength along the flute length

Compatibility

Designed as an OEM-style screw machine length drill bit for use in standard drill chucks accepting straight-cylindrical shanks; primary workpiece materials are steel and alloy steel as specified by the manufacturer.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before drilling. Always operate within the spindle speed and feed rate range appropriate for the workpiece material and bit diameter. Wear appropriate eye protection and ensure the workpiece is firmly clamped before beginning any drilling operation.
