Osg 650062511 Screw Machine Drill Bit 0.6252 in Carbide

Product Description

The OSG 650062511 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series 6500 specifications, this bit features a 140-degree drill point angle, spiral flute geometry, and an R-thinned, tapered web configuration that improves chip evacuation and reduces thrust at entry. Coolant-through capability supports extended tool life in high-cycle production environments. The straight-cylindrical shank provides secure seating in standard drill chucks and collet holders. At 0.6252 inches (15.88 mm) in diameter, this bit is sized for precise bore work where dimensional tolerance is critical.

The OSG 650062511 is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys in machining centers, CNC drilling operations, and manual machine shop setups. The screw machine length format — shorter overall length than jobber bits — provides added rigidity and improved concentricity in short-reach drilling applications. The 3xD flute-to-diameter ratio and right-hand spiral flute pattern support controlled chip removal in both through-hole and blind-hole operations. This bit is typically used by machinists, tool-and-die technicians, and CNC operators working with ferrous and exotic materials.

Key Features

• Solid carbide construction for high hardness and wear resistance in ferrous and exotic materials
• 140-degree drill point angle reduces breakthrough burring and improves centering on hard materials
• Coolant-through design supports high-speed production drilling and extended bit life
• R-thinned, tapered web reduces cutting resistance and lowers thrust force at entry
• Screw machine length format increases rigidity compared to jobber-length bits
• Straight-cylindrical shank compatible with standard chucks and collet holders

Compatibility

Designed for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Fits standard drill chucks and collet holders accepting a 0.6252-inch straight-cylindrical shank. Part of OSG Series 6500 high-performance carbide drilling tools.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine fully powered down and spindle stopped before bit insertion or removal. Ensure the chuck or collet is properly torqued to the manufacturer specification for the holding device in use. Coolant lines should be confirmed clear and flowing before beginning high-speed production runs with coolant-through tooling. Follow applicable shop safety standards and machine tool manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
