Osg 8595165 Screw Machine Drill Bit 1.65 Mm Hss

Product Description

The OSG 8595165 is a screw machine length drill bit ground from high speed steel and designed for high-performance drilling in tight, close-tolerance applications. At 1.65 mm in diameter with a 140-degree faceted point, it delivers clean entry and reduced thrust compared to standard 118-degree geometry. The two-flute spiral design with a web-thinned, tapered web configuration promotes efficient chip evacuation. Overall length is 42 mm (1.654 inches) with a 3 mm straight-cylindrical shank. This bit is suited for use in CNC machining centers, drill presses, and hand-held pneumatic or electric tools where compact cutting length is required. Licensed machinists and tool-and-die technicians are the primary users.

The OSG 8595165 is built for production drilling in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. Its screw machine length body — shorter than jobber length — provides added rigidity and improved concentricity in high-cycle production environments. The 5xD flute-to-diameter ratio supports adequate chip clearance at typical drilling depths for this diameter class. It is a solid choice for sheet metal fabrication, precision machining, and general production work where small-diameter, close-tolerance holes are required.

Key Features

• 140-degree faceted point reduces thrust and improves entry accuracy on hard and abrasive materials
• High speed steel construction with coated finish for extended tool life
• Web-thinned tapered web reduces cutting resistance and aids chip flow
• Screw machine (stub) length body improves rigidity over jobber-length alternatives
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cut with regular spiral flutes; compatible with conventional drill press and CNC spindle rotation

Compatibility

OSG Series 1100 screw machine length drill bit rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Fits any standard chuck or collet accepting a 3 mm straight shank. Drill bit diameter tolerance is plus 0 to minus 0.014 mm.

Installation Notes

Installation and use should be performed by qualified machinists or trained tool operators familiar with small-diameter drill bit handling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits to avoid bit deflection or breakage at this diameter. Small-diameter bits are sensitive to side loading — use a center punch or spot drill to establish a starting point before drilling. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling steel or stainless steel to manage heat and extend tool life.
