Osg 8595072 Screw Machine Drill Bit 0.72mm Hss Tin

Product Description

The OSG 8595072 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 measures 0.72 mm (0.0283 inches) in diameter with an overall length of 38 mm (1.4961 inches). The 150-degree faceted point geometry reduces thrust and improves entry accuracy on hard materials. A web-thinned, tapered web configuration further lowers cutting resistance at the tip. This bit is suited for CNC machine tools, drill presses, and screw machine setups where compact overall length and precise hole quality are required.

This drill bit is intended for use in production machining environments and precision fabrication shops. Its short screw machine length provides added rigidity compared to jobber-length bits, making it well suited for close-tolerance work on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank measures 3.00 mm (0.1181 inches) in diameter, compatible with standard collets and chucks used in CNC and manual machine tool setups. It is typically installed and operated by machinists and tool-and-die professionals.

Key Features

• High-speed steel construction with titanium nitride (TiN) coating for extended tool life on ferrous and non-ferrous materials
• 150-degree faceted point reduces entry thrust and improves hole location accuracy
• Web-thinned tapered web lowers cutting resistance at the drill tip
• Screw machine length (38 mm OAL) provides greater rigidity over standard jobber-length bits
• Right-hand spiral flute with 5xD flute-to-diameter ratio for efficient chip evacuation
• Straight-cylindrical 3.00 mm shank fits standard collets and drill chucks

Compatibility

OSG Series 1100 screw machine length drill bit designed for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Suitable for CNC machining centers, drill presses, and screw machine setups accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Ensure the machine spindle is fully stopped and the tool holder or chuck is properly secured before mounting or removing the bit. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning a cut. Do not exceed the recommended depth of cut for the flute length, as this bit has a flute length of 4.50 mm.
