Osg 570040611 Screw Machine Drill Bit 0.4063 in Solid Carbide

Product Description

The OSG 570040611 is a solid carbide screw machine length drill bit designed for high-performance drilling in steel, alloy steel, and cast iron. Built to Series 5700 specifications, it features a 180-degree drill point angle with web thinning for improved penetration and reduced thrust. The straight-cylindrical shank provides secure chuck engagement, while the two-flute spiral design promotes efficient chip evacuation. At 0.4063 inches (13/32 inch) in diameter and 90.00 mm overall length, this bit is sized for screw machine length applications where a compact, rigid tool is required. A coated finish extends cutting life in demanding ferrous materials. Installation is performed by machinists and tool-and-die professionals working with CNC machining centers, turret lathes, or screw machines.

This drill bit is suited for production drilling in ferrous workpiece materials including steel, alloy steel, and cast iron. The screw machine length format keeps the tool short and rigid, reducing deflection during high-feed operations. The 2xD flute-by-diameter ratio supports standard drilling depths in these materials. Typical applications include component manufacturing, repetitive hole generation in metal stock, and precision through-hole operations where dimensional consistency is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 180-degree drill point angle with web-thinned, tapered web for lower entry thrust
• Two-flute regular spiral geometry promotes chip clearance during drilling
• Coated finish extends tool life in steel and alloy steel applications
• Screw machine length body reduces deflection in short-reach setups
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces. Compatible with standard drill chucks and collet systems accepting a straight-cylindrical shank at 0.4063 inch diameter. Part of the OSG Series 5700 high-performance drill line.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Verify spindle runout is within acceptable limits before seating the shank, as carbide is brittle and sensitive to lateral loading. Confirm the workpiece is securely fixtured before initiating the cut. Coolant-through is not supported on this tool, so adequate flood or mist coolant at the cutting zone is recommended for production drilling in ferrous materials.
