Osg 8595206 Screw Machine Drill Bit Size 46 Hss Tin

Product Description

The OSG 8595206 is a screw machine length drill bit designed for high-precision, short-reach drilling in production and maintenance environments. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction across a wide range of workpiece materials. The bit features a 130-degree faceted point angle, a fast spiral flute configuration, and a web-thinned parallel web design that reduces entry force and improves chip evacuation. The overall length is 1.7323 inches (44 millimeters), making it well-suited for screw machine setups and close-clearance drill press applications. Licensed machinists, tool and die technicians, and maintenance mechanics are the typical end users for this style of bit.

This drill bit is rated for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length body keeps the working length compact, which improves rigidity and reduces runout in high-cycle production drilling. The straight-cylindrical shank with a 0.1181-inch (3.00 millimeter) diameter mounts directly into standard drill chucks, collets, and screw machine spindles without adapters. The Series 1100 designation places this bit within the OSG high-performance grade range, targeting applications where standard jobber-length bits introduce too much flex or deflection.

Key Features

• Wire gauge size 46 (0.0810 inch decimal equivalent) for precision bore sizing
• TiN coating reduces friction and extends cutting edge life versus uncoated HSS
• 130-degree faceted point angle for positive self-centering on flat and curved surfaces
• Fast spiral flute geometry promotes aggressive chip evacuation in short-chipping materials
• Web-thinned parallel web reduces thrust force and minimizes drill walk at entry
• Screw machine length body (44 millimeters OAL) provides superior rigidity over jobber-length alternatives

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with standard drill chucks and collet systems accepting a 3.00 millimeter straight-cylindrical shank. Rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Installation Notes

This bit is installed by machinists, tool and die technicians, and maintenance mechanics using standard drill chucks or collet holders. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank diameter compatibility with the chuck or collet before seating; the 3.00 millimeter shank requires a properly sized collet for concentricity. Coolant-through is not supported on this bit; use external cutting fluid appropriate to the workpiece material when drilling stainless steel or high-silicon aluminum alloys.
