Osg 8595322 Screw Machine Drill Bit 0.1268 in Hss 130

Product Description

The OSG 8595322 is a screw machine length drill bit designed for high-performance drilling in metal fabrication and machining applications. Built from high speed steel (HSS) with a coated finish, it measures 0.1268 inches (3.22 mm) in diameter with a 130-degree faceted point angle. The two-flute spiral design with web thinning and a tapered web configuration reduces entry force and improves chip evacuation. The straight-cylindrical shank diameter measures 0.157 inches (4.00 mm). Overall length is 1.969 inches (50.00 mm) with a flute length of 0.709 inches (18.00 mm). This bit belongs to OSG Series 1100 and is rated for high-performance use. Machinists, tool-and-die workers, and CNC operators are the primary users.

This screw machine length drill bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its compact screw machine length provides increased rigidity compared to jobber-length bits, making it well suited for drill press, CNC machining center, and turret lathe applications where shorter reach and reduced deflection are critical. The right-hand cut spiral flute with a 5xD flute-to-diameter ratio supports efficient chip clearing in these materials.

Key Features

• 0.1268 inch (3.22 mm) diameter with a tight tolerance of +0 to -0.0007 inches (-0.018 mm)
• 130-degree faceted point angle reduces walking and improves hole entry accuracy
• Web-thinned tapered web lowers thrust and cutting resistance at the drill tip
• High speed steel construction with coated finish for extended tool life in ferrous and non-ferrous materials
• Screw machine length body increases rigidity and reduces deflection versus jobber-length bits
• Right-hand cut, 2-flute spiral design promotes consistent chip evacuation

Compatibility

The OSG 8595322 is part of the Series 1100 product family and is designed for use with workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. It fits standard straight-shank drill chucks and collet systems accepting a 0.157 inch (4.00 mm) shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with cutting tool setup and machine tool operation. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation, and verify that spindle speed and feed rate are appropriate for the workpiece material and drill diameter. Inspect the cutting edges for wear or damage before each use, and do not use a chipped or worn bit. Coolant-through is not supported on this bit; apply external cutting fluid as needed for the workpiece material.
