Osg 3330300 Screw Machine Drill Bit 0.1181 in Carbide

Product Description

The OSG 3330300 is a solid carbide screw machine length drill bit designed for high-performance drilling in metalworking applications. It measures 3.00 mm (0.1181 inches) in diameter with a 180-degree drill point angle and a right-hand spiral flute configuration. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 55.00 mm (approximately 2.17 inches). Web-thinned construction reduces entry force and improves chip evacuation. This bit is intended for use by machinists, tool and die professionals, and production drilling operators working with tight-tolerance bores in steel, alloy steel, and cast iron.

The OSG 3330300 belongs to the Series 5700 and is rated for primary workpiece materials including steel, alloy steel, and cast iron. Its screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection, making it well-suited for CNC machining centers, drill presses, and turret lathes where stub-length stiffness is required. The 2xD flute-to-diameter ratio and tapered web configuration are optimized for short, controlled chip formation in ferrous materials. This is a single-piece unit with no coolant-through capability.

Key Features

• Solid carbide construction for extended tool life in ferrous metals
• 180-degree drill point angle for flat-bottom entry geometry
• Web-thinned, tapered web design reduces thrust and improves chip flow
• Screw machine (stub) length provides superior rigidity over jobber-length bits
• Straight-cylindrical 6.00 mm shank for standard collet and chuck compatibility
• Diameter tolerance of +0 to -0.014 mm for precision bore sizing

Compatibility

Designed for use in CNC machining centers, drill presses, and turret lathes accepting a straight-cylindrical shank. Primary workpiece materials include steel, alloy steel, and cast iron. Part of the OSG Series 5700 high-performance solid carbide drill platform.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Before inserting or removing the bit, ensure the spindle is fully stopped and the machine is locked out or powered down per applicable safety procedures. Verify collet or chuck runout is within acceptable tolerance before operation, as carbide is brittle and sensitive to lateral loading. Do not use this bit on materials outside its rated workpiece category, as unexpected breakage may occur.
