Osg 6160711 Screw Machine Drill Bit 10.70mm Tialn Hss

Product Description

The OSG 6160711 is a stub-length screw machine drill bit designed for high-production drilling in metal fabrication and machining applications. Built from vanadium high speed steel and finished with a TiAlN coating, it delivers extended tool life at elevated cutting speeds compared to uncoated HSS tooling. The 120-degree, 4-facet point geometry promotes accurate self-centering and reduces walking on entry, while the tapered web adds rigidity through the cut. At 10.70 mm (0.4213 inches) in diameter with a 104.00 mm overall length, this bit fits standard straight-shank toolholders and is sized for use in drill presses, CNC machining centers, and manual machines.

This drill bit is suited for use in metalworking shops, maintenance and repair operations, and light manufacturing environments. Its stub length reduces deflection and improves hole straightness in short-depth applications. The right-hand spiral flute configuration handles chip evacuation in a wide range of ferrous and non-ferrous materials. It is a common choice for machinists and tool-and-die technicians working in production drilling scenarios where tool longevity and dimensional consistency matter.

Key Features

• TiAlN coating extends cutting life and performs well at higher surface speeds and temperatures
• 120-degree, 4-facet point geometry for accurate self-centering entry and reduced thrust force
• Vanadium high speed steel substrate provides toughness and wear resistance
• Stub length reduces deflection and improves rigidity in short-hole drilling
• Tapered web configuration adds strength at the core without sacrificing chip clearance
• Straight shank at 12.00 mm (0.4724 inches) fits standard ER collets and drill chucks

Compatibility

Designed as an OEM-style replacement or direct application bit within the OSG Series 1100 stub-length drill line, compatible with straight-shank toolholders accepting a 12.00 mm shank diameter in the 9.50 to 11.00 mm drill bit size range.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Verify that the chuck or collet is rated for the 12.00 mm shank diameter and that runout is within acceptable limits before starting the cut. Do not exceed the recommended cutting parameters for the workpiece material and coating type.
