Osg 8595163 Screw Machine Drill Bit 0.0642 in Hss

Product Description

The OSG 8595163 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from high speed steel (HSS) with a coated finish, this bit measures 0.0642 inches (1.63 mm) in diameter with an overall length of 42.00 mm and a flute length of 10.00 mm. The 140-degree faceted point angle reduces walking and improves entry on hard materials. A web-thinned, tapered web configuration lowers thrust requirements and improves chip evacuation. This bit is intended for use by machinists, tool and die technicians, and precision metalworkers operating drill presses, CNC machines, or manual lathes.

The OSG 8595163 is suited for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Its screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection in tight setups or fixture work. The straight-cylindrical shank with a 3.00 mm shank diameter seats securely in standard chucks. The 5xD flute-to-diameter ratio supports efficient chip removal during short-cycle production drilling. This bit fits Series 1100 applications and is packaged individually.

Key Features

• 0.0642-inch (1.63 mm) diameter with a tolerance of +0 to -0.014 mm for precise hole sizing
• 140-degree faceted point reduces bit walking and improves penetration on steel and stainless steel
• Web-thinned, tapered web lowers cutting thrust and extends tool life
• High speed steel construction with coated finish for wear resistance
• Screw machine length provides extra rigidity and reduced deflection versus jobber-length bits
• Right-hand spiral flute design for standard clockwise drilling operations

Compatibility

Designed for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits standard chucks accepting a 3.00 mm straight-cylindrical shank. Part of the OSG Series 1100 screw machine drill line.

Installation Notes

This bit should be installed by qualified machinists or tool operators familiar with small-diameter tooling. Ensure the drill press or CNC spindle is fully stopped before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting this bit does not support through-coolant. Avoid excessive feed pressure on small-diameter bits to prevent breakage.
