Osg 3330210 Screw Machine Drill Bit 2.10mm Carbide

Product Description

The OSG 3330210 is a screw machine length drill bit engineered for high-performance drilling in demanding materials. Built from solid carbide and finished with OSG's proprietary EgiAs multi-layer coating, it delivers consistent performance in steel, cast iron, and hardened materials. The 180-degree flat-bottom point geometry allows drilling to a true flat floor, a key advantage in precision machining and spotting applications. At 2.10 mm in diameter and 50.00 mm overall length (1.9685 inches), this compact bit is suited for CNC machining centers and drill presses where short, rigid tooling is required. A web-thinned, tapered web configuration reduces entry force and improves chip evacuation.

This drill bit is designed for use in machine shop and production environments where tight tolerances and repeatable results are required. Primary workpiece materials include steel, cast iron, and hardened materials. The 2xD flute-to-diameter ratio and screw machine length body keep deflection low in short-depth applications. Machinists, toolmakers, and CNC operators working in job shop, aerospace, automotive, and die-mold settings will find this bit well suited for high-cycle drilling operations where tool life and hole quality are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs proprietary multi-layer coating reduces friction and extends tool life in steel and cast iron
• 180-degree flat-bottom point produces a true flat-floor hole without a center cone
• Web-thinned tapered web reduces thrust force and improves chip flow
• Screw machine length (2xD flute ratio) minimizes deflection in short-reach drilling
• Straight cylindrical shank with 4.00 mm shank diameter fits standard collets and drill chucks

Compatibility

Designed as an OEM-style production drill bit in the OSG Series 5700 line, suitable for use in standard straight-shank collet chucks and drill press spindles accepting a 4.00 mm shank diameter.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Ensure the machine spindle and collet are clean and properly seated before securing the shank to prevent runout. Solid carbide tooling is brittle and should not be used in hand-held drilling applications or on machines with excessive spindle play. Follow the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
