Osg 8595105 Screw Machine Drill Bit 1.05 Mm Tin Hss

Product Description

The OSG 8595105 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The 140-degree faceted point promotes accurate entry and reduces walking on hard materials. At 38 millimeters overall length with a 6 millimeter flute length, this stub-length bit provides rigidity for precise, repeatable holes in production environments. It is suited for use in CNC machining centers, drill presses, and automatic screw machines. Licensed machinists and tool-and-die professionals are the primary installers.

This bit is built for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format makes it a practical choice for high-cycle production drilling where shorter overhang reduces deflection and chatter. The straight-cylindrical shank with a 3 millimeter diameter fits standard collets and chucks in the same size range. The Series 1100 designation places it within OSG standard stub-length drilling inventory.

Key Features

• TiN coating extends tool life and reduces heat buildup during high-cycle drilling
• 140-degree faceted point reduces thrust force and improves hole entry accuracy
• Web-thinned, tapered web construction lowers cutting resistance in hard materials
• Regular spiral flute geometry handles chip evacuation across steel and aluminum workpieces
• Screw machine length body provides added rigidity compared to jobber-length bits
• Right-hand cutting direction compatible with standard drill press and CNC spindle rotation

Compatibility

Designed for use with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits standard collets and chucks accepting a 3 millimeter straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Secure the shank fully in the collet or chuck before operation and verify runout before beginning production runs. Always match spindle speed and feed rate to the workpiece material and bit diameter per standard machining practice. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.
