Osg 10140605 Screw Machine Drill Bit 0.1406in Cobalt Hss

Product Description

The OSG 10140605 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, it offers enhanced heat and wear resistance compared to standard HSS tooling. The bit measures 0.1406 inches (9/64 inches) in diameter with a 130-degree point angle and a spiral flute geometry. An X-thinned web reduces thrust during entry and improves chip evacuation. At 2-3/8 inches overall length, this stub-length bit is well suited for tight-clearance drilling in production and maintenance environments. It is installed and used by machinists, tool and die technicians, and skilled tradespeople working with ferrous metals.

This drill bit is intended for use in screw machine, drill press, and CNC drilling operations where rigidity and precision are required. The shorter screw machine length improves stiffness and reduces deflection, making it a practical choice for drilling in steel and alloy steel workpieces. With a right-hand cut and straight-cylindrical shank, it fits standard drill chucks and collet holders without modification. The Series 1000 designation places it within OSG general-purpose cobalt HSS tooling. Typical applications include repetitive production drilling, fixture work, and maintenance machining where hole accuracy and tool life matter.

Key Features

• Cobalt high speed steel construction for improved heat resistance and tool life in ferrous materials
• 130-degree point angle with X-thinned web reduces entry thrust and improves self-centering
• Screw machine (stub) length increases rigidity and reduces deflection compared to jobber-length bits
• Spiral flute with tapered web configuration promotes efficient chip removal
• Right-hand cut, straight-cylindrical shank fits standard chucks and collet holders
• Coated finish for added surface protection and reduced friction during cutting

Compatibility

Designed as a screw machine length replacement or production drill bit for use in steel and alloy steel machining applications with standard straight-shank drill chucks and collet systems.

Installation Notes

This drill bit is intended for use by machinists and tradespeople familiar with drill press, lathe, or CNC drilling operations. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Use appropriate cutting fluid or coolant for steel drilling to extend tool life, even though coolant-through is not featured on this bit. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material and hole diameter.
