Osg 8595233 Screw Machine Drill Bit 2.33mm Tin Hss

Product Description

The OSG 8595233 is a screw machine length drill bit designed for high-performance drilling in metal and alloy materials. Built from vanadium high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 130-degree faceted point geometry promotes accurate entry and minimizes walking on entry, while the web-thinned, tapered web configuration reduces thrust force. At 45 millimeters overall length and 2.33 mm diameter, this is a compact, stubby-format bit suited to close-quarters drilling and screw machine operations. Right-hand cut with a regular spiral flute and straight cylindrical shank.

This bit is used in screw machine setups, CNC turning centers, drill presses, and hand-held power tools where a short, rigid drill is needed to maintain accuracy. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The 5xD flute-to-diameter ratio supports chip evacuation in these materials. Typical applications include production machining, precision hole-making in metal fabrication, and maintenance work where tight tolerances are required.

Key Features

• Vanadium high speed steel construction with TiN coating for wear resistance and heat reduction
• 130-degree faceted point angle for accurate entry and reduced drill walk
• Web-thinned, tapered web reduces axial thrust and improves chip flow
• Screw machine length format provides rigidity in close-quarter and machine setups
• Regular spiral flute with 5xD ratio supports chip evacuation in steel and aluminum
• Straight cylindrical shank compatible with standard drill chucks and collets
• Right-hand cut with 2-flute design for general-purpose metal drilling

Compatibility

Designed for use with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits standard drill chucks and collets accepting a 3.00 mm straight cylindrical shank. Part of the OSG Series 1100 high-performance drill line.

Installation Notes

This bit is installed and operated by machinists, toolroom technicians, and maintenance mechanics. Before changing tooling, power down and de-energize the machine spindle fully. Secure the straight shank in a properly sized collet or drill chuck and confirm runout before production use. Follow the machine tool manufacturer guidelines for feed rate and spindle speed when drilling the target workpiece material.
