Osg 3330400 Screw Machine Drill Bit 0.1575 in Carbide

Product Description

The OSG 3330400 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metal-cutting applications. With a 0.1575 inch (4.00 mm) diameter and a 180-degree drill point angle, this bit delivers a flat-bottom entry suitable for precision hole-making without a pilot point. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 60.00 mm (approximately 2.36 inches). Web thinning with a tapered web configuration reduces thrust and improves chip evacuation. This bit belongs to OSG Series 5700 and is rated for high-performance use by machinists and tool-and-die professionals.

This drill bit is engineered for use in steel, alloy steel, and cast iron workpieces. Its screw machine (stub) length provides added rigidity compared to jobber-length bits, making it well suited for CNC machining centers, manual knee mills, and drill presses where shorter overhang reduces deflection. The 2xD flute-by-diameter ratio supports efficient chip removal in short-hole drilling operations. It is a practical choice for production environments where consistent hole tolerance and tool life are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 180-degree drill point angle for flat-bottom entry without a separate spotting operation
• Web-thinned, tapered web design reduces axial thrust and improves chip flow
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut, regular spiral flute geometry for standard CNC and manual machine use
• Coated finish extends tool life in steel and alloy steel applications

Compatibility

Designed as a high-performance screw machine length carbide drill bit for use in steel, alloy steel, and cast iron workpieces. Compatible with standard straight-shank drill chucks and collet systems accepting a 6.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool-and-die technicians familiar with cutting tool selection and machine setup. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the shank to the recommended collet or chuck torque specification for the holder in use. Coolant-through is not supported on this bit; apply external coolant or cutting fluid as appropriate for the workpiece material and feed rate.
