Osg 3334342 Screw Machine Drill Bit 6mm Carbide

Product Description

The OSG 3334342 is a solid carbide screw machine length drill bit designed for high-performance drilling in steel, alloy steel, and cast iron. Built to Series 5720 specifications, it features a 6.00 mm diameter with a 180-degree web-thinned point that reduces entry force and improves centering accuracy. The EgiAs coating provides enhanced wear resistance and heat dissipation at the cutting edge. With an overall length of 65.00 mm and a flute length of 27.00 mm, this stub-length bit delivers rigidity and reduced deflection in production and repair drilling applications. Coolant-through capability supports chip evacuation in deep or interrupted cuts. This bit is installed by machinists, tool-and-die workers, and maintenance technicians working with CNC and manual drilling equipment.

The OSG 3334342 is suited for drilling operations in ferrous materials including carbon steel, alloy steel, and cast iron. Its screw machine length profile makes it well-matched to drill press, CNC machining center, and turret lathe applications where short tool overhang is required for stability. The 3xD flute-to-diameter ratio and regular spiral geometry support efficient chip removal in through-hole and blind-hole configurations. It is appropriate for both production environments and precision maintenance work where consistent hole tolerance is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• EgiAs coating applied to both the drill tip and flute for extended tool life
• 180-degree web-thinned, tapered-web point reduces thrust and improves hole entry accuracy
• Coolant-through design supports chip evacuation and thermal management in deep cuts
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Screw machine length body provides reduced overhang and improved stability versus jobber-length bits

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard 6.00 mm straight-shank drill chucks and collet systems on CNC machining centers, drill presses, and turret lathes. Primary workpiece materials are steel, alloy steel, and cast iron.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tool handling. Ensure the machine spindle is fully stopped and de-energized before inserting or removing the bit from the chuck or collet. Verify chuck or collet runout is within acceptable tolerance before operation, as excessive runout accelerates carbide tool wear. Coolant-through applications require that the coolant supply is confirmed clear and at correct pressure before engaging the cut.
