Osg 8595282 Screw Machine Drill Bit Size 34 Hss Tin

Product Description

The OSG 8595282 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. Built from high-speed steel with a titanium nitride (TiN) coating, it runs at a wire gauge size 34, equivalent to 0.1110 inches (2.82 mm) in diameter. The 130-degree faceted point angle promotes accurate entry and reduces walking on hard materials. At 1.8898 inches (48 mm) overall length, this stub-length bit is well suited for close-quarters drilling where a jobber-length bit will not fit. Licensed trades and machine shop personnel are the primary installers.

This bit is built for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format makes it a common choice for drill press work, CNC applications, and bench drilling operations where rigidity and reduced deflection matter. The 5xD flute-to-diameter ratio supports chip evacuation in deeper hole passes. Web thinning reduces thrust requirements at entry, which is useful when working with harder ferrous materials.

Key Features

• TiN coating extends tool life and reduces friction on ferrous and non-ferrous materials
• 130-degree faceted point for accurate self-centering and reduced thrust
• Web-thinned, tapered web configuration lowers entry resistance
• Screw machine (stub) length provides increased rigidity and reduced deflection
• Right-hand spiral flute promotes efficient chip removal
• No coolant-through design suited for standard bench and CNC drilling setups

Compatibility

Compatible with drilling operations involving steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Designed as an OEM-style replacement or direct procurement option within the OSG Series 1100 screw machine drill line.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press, lathe, or CNC equipment. Secure the straight-cylindrical shank firmly in the chuck before operation and verify concentricity to avoid runout. Always power down and de-energize equipment before changing tooling. Follow applicable shop safety standards and equipment manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
