Osg 3330500 Carbide Screw Machine Drill Bit 0.1969 in

Product Description

The OSG 3330500 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. It carries a 5.00 mm (0.1969 inch) diameter with a 180-degree flat point geometry, making it well suited for flat-bottom hole applications and precise entry without a center drill. The straight-cylindrical shank seats securely in standard chucks and collets. With a 2-flute spiral flute configuration, web-thinned tapered web, and coated finish, this bit is built to handle demanding production environments where tool life and hole quality in steel and cast iron are priorities.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machine operations targeting steel, alloy steel, and cast iron workpieces. The screw machine length format — shorter overall length for added rigidity — is a common choice in production shops, job shops, and maintenance machining environments. It belongs to the OSG Series 5700 high-performance carbide drill line and is sized within the 0.1500 to 0.2000 inch decimal inch range for drop-in replacement in existing programs.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 180-degree flat drill point for flat-bottom holes and no-pilot-drill entry
• Web-thinned tapered web reduces thrust and improves chip evacuation
• 2-flute spiral flute design promotes consistent chip flow
• Coated finish extends tool life in steel and alloy steel applications
• Screw machine length body (65.00 mm overall) provides extra rigidity over jobber-length bits

Compatibility

Designed for use on steel, alloy steel, and cast iron workpieces. Straight-cylindrical shank with 6.00 mm shank diameter fits standard drill chucks and ER collet systems accepting that shank size. Part of OSG Series 5700.

Installation Notes

This bit is installed by machinists and toolroom technicians in CNC or manual machine setups. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Coolant-through is not supported on this model, so adequate external coolant or cutting fluid should be applied when drilling steel or cast iron at production feeds and speeds. Follow shop-standard tool change lockout procedures when swapping bits in live tooling or CNC turrets.
