Osg 8595295 Screw Machine Drill Bit 0.116 in Hss

Product Description

The OSG 8595295 is a screw machine length drill bit designed for high-performance drilling in metal fabrication, machining, and general trade applications. Built from high speed steel with a coated finish, this bit features a 130-degree faceted drill point and a web-thinned, tapered web configuration that reduces cutting resistance at entry. The straight-cylindrical shank measures 3.00 mm (approximately 0.118 inches) in diameter, and the overall length is 48.00 mm (approximately 1.89 inches). With a two-flute spiral design and a 5xD flute-to-diameter ratio, it is suited for production environments where stub-length rigidity is required. Machinists, tool-and-die technicians, and CNC operators are the primary users.

This drill bit is sized at 0.116 inches in diameter, equivalent to wire gauge number 32 and approximately 2.95 mm. The screw machine length format provides greater rigidity than jobber-length bits, making it a practical choice for drilling in tight clearances or on drill presses and CNC machining centers. It is rated for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials, covering a broad range of production and maintenance machining tasks.

Key Features

• High speed steel construction with coated finish for wear resistance
• 130-degree faceted drill point for positive engagement on hard materials
• Web-thinned, tapered web reduces thrust and improves chip evacuation
• Screw machine length provides extra rigidity compared to jobber-length bits
• Right-hand cut, two-flute spiral design compatible with standard drill chucks and CNC toolholders
• Covers wire gauge 32 applications with a diameter tolerance of +0 to -0.014 mm

Compatibility

Designed as an OEM-style replacement or direct-fit drill bit for wire gauge 32 applications within the 0.1000 to 0.1500 inch decimal inch size range, compatible with straight-shank drill chucks on drill presses, CNC machining centers, and hand-held power drills.

Installation Notes

Installation and use should be performed by qualified machinists or trained trade professionals familiar with rotating cutting tool safety. Secure the shank fully in the chuck and confirm runout is within acceptable limits before starting a cut. Always bring spindle speed to zero and isolate machine power before changing tooling. Do not exceed the recommended speed-and-feed parameters for the workpiece material being drilled.
