Osg 3330620 Screw Machine Drill Bit 6.20mm Carbide

Product Description

The OSG 3330620 is a screw machine length drill bit designed for high-performance drilling in steel, alloy steel, and cast iron. It is built from solid carbide and coated with OSG EgiAs coating to extend tool life and reduce wear in demanding production environments. The bit measures 6.20 mm in diameter with a 180-degree flat point and a 70 mm overall length, making it well suited for short-hole drilling where rigidity and precision matter. With a right-hand spiral flute and web-thinned point, it delivers clean entry and efficient chip evacuation. Machinists, tool-and-die shops, and production floor operators are the primary users.

This bit is built for use in CNC machining centers, drill presses, and screw machine applications where a short, stub-length tool is preferred for improved stability and reduced deflection. Its 2xD flute-to-diameter ratio and tapered web configuration make it effective in production settings that require consistent, repeatable results when drilling steel and cast iron workpieces. The straight cylindrical shank fits standard drill chucks and collet systems without special tooling.

Key Features

• Solid carbide construction for hardness and heat resistance in ferrous materials
• EgiAs coating reduces friction and extends tool life in steel and cast iron
• 180-degree flat point with web thinning for fast, accurate drill entry
• Screw machine length body provides greater rigidity than jobber-length bits
• Right-hand spiral flute with regular helix for efficient chip removal
• Straight cylindrical shank fits standard chucks and collet holders

Compatibility

Designed for drilling steel, alloy steel, and cast iron. Compatible with standard drill chucks and collet systems accepting a 6 mm straight cylindrical shank. Suitable for CNC machining centers and screw machine setups requiring a stub-length carbide drill in the 5.00 to 6.50 mm diameter range.

Installation Notes

Installation and use of solid carbide drill bits should be performed by qualified machinists or tool operators familiar with cutting tool safety. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the bit from the chuck or collet. Confirm shank runout is within acceptable tolerance before beginning a production run, as carbide tooling is sensitive to lateral stress. Follow machine manufacturer guidelines for speed and feed settings appropriate to the workpiece material.
