Osg 11515915 Screw Machine Drill Bit 0.082 in Hss

Product Description

The OSG 11515915 is a screw machine length drill bit designed for short-hole drilling applications where rigidity and precision matter. Built from high speed steel (HSS) with a coated finish, it cuts a 0.082 inch (Wire Size 45) diameter hole with a right-hand spiral flute configuration. The 130-degree faceted drill point and web-thinned tip reduce entry force and improve chip evacuation on entry. Overall length is 44.00 millimeters (approximately 1.73 inches) with a straight-cylindrical shank measuring 3.00 millimeters (approximately 0.118 inches) in diameter. This bit is rated high performance and suits production drilling environments where a shorter flute-to-diameter ratio of 3xD keeps deflection low.

This bit is suited for drilling steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length profile makes it a practical choice for CNC machining centers, drill presses, and turret lathes where stub-length tooling is preferred for reduced runout and improved hole accuracy. It is commonly used in light manufacturing, maintenance shops, and precision fabrication settings where small-diameter hole quality is critical.

Key Features

• 0.082 inch diameter (Wire Size 45, 2.08 mm) with a tight tolerance of +0 to -0.014 mm
• 130-degree faceted drill point for reduced thrust and clean entry
• Web-thinned tapered web construction improves chip flow and reduces walking
• High speed steel construction with coated finish for extended tool life on ferrous and non-ferrous materials
• Right-hand cut, 2-flute spiral configuration for standard drilling operations
• Screw machine (stub) length with 3xD flute-to-diameter ratio for maximum rigidity

Compatibility

OSG Series 1150 screw machine length drill bit designed for use in standard straight-shank tool holders compatible with a 3.00 millimeter (approximately 0.118 inch) shank diameter. Suitable for drilling steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Installation Notes

Install in a compatible straight-shank chuck or collet holder and verify concentricity before drilling to minimize runout on small-diameter work. Ensure the workpiece is securely fixtured before operation. Use cutting fluid appropriate for the workpiece material to extend tool life. Replace the bit if the cutting edge shows signs of chipping or the hole diameter drifts outside tolerance.
