Osg 3330510 Screw Machine Drill Bit 5.1 Mm Solid Carbide

Product Description

The OSG 3330510 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. With a 5.1 mm diameter, a 180-degree web-thinned point, and a straight-cylindrical shank, this bit delivers accurate entry and reduced thrust in tight-tolerance applications. The overall length is 65 mm (2.56 inches), making it suitable for screw machine and short-reach operations where rigidity matters. Two spiral flutes with a 24 mm flute length provide reliable chip evacuation. The coated finish extends tool life under demanding cutting conditions. This bit is intended for use by machinists, tool-and-die professionals, and industrial maintenance technicians working with precision drilling equipment.

The OSG 3330510 is rated for primary use in steel, alloy steel, and cast iron workpieces. Its screw machine length profile makes it a practical choice for CNC machining centers, turret lathes, and drill presses where stub-length rigidity reduces deflection and improves hole location accuracy. The 6 mm shank diameter fits standard collets and drill chucks common in production machine shop environments. The web-thinned, tapered web configuration reduces the chisel edge load on entry, which is especially useful when drilling into hard ferrous stock at higher feed rates.

Key Features

• Solid carbide construction for high rigidity and wear resistance in ferrous materials
• 180-degree web-thinned point reduces thrust and improves self-centering on entry
• Screw machine length (65 mm OAL) provides maximum rigidity and minimizes deflection
• 2xD flute-to-diameter ratio with 24 mm spiral flutes for efficient chip removal
• Coated finish extends cutting life under high-speed or dry cutting conditions
• Right-hand cut, straight-cylindrical shank compatible with standard collets and chucks

Compatibility

Designed as a screw machine length replacement drill bit for use in steel, alloy steel, and cast iron applications. Part of the OSG Series 5700 line. Shank diameter is 6 mm; drill bit diameter tolerance is plus 0 to minus 0.018 mm. Fits within the 5.00 mm to 6.50 mm drill bit size range category.

Installation Notes

This bit should be installed by a qualified machinist or trained maintenance technician familiar with carbide tooling. Secure the shank fully in the collet or chuck and verify runout before operation, as carbide is brittle and sensitive to lateral shock or improper seating. Power down all spindle drives before changing tooling. Avoid side loads or interrupted cuts that can chip the carbide cutting edge.
