Osg 650057711 Screw Machine Drill Bit 37/64 Solid Carbide

Product Description

The OSG 650057711 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. It measures 0.5778 inches (37/64 inch) in diameter with a 140-degree split point and features a right-hand spiral flute with R-thinned web for improved chip evacuation and reduced thrust at entry. The straight-cylindrical shank provides secure chuck retention. With coolant-through capability and a coated finish, this bit is built for production environments where tool life and hole quality are critical. Licensed machinists and tool-and-die professionals are the primary installers.

This drill bit is suited for screw machine operations and short-hole drilling in steel, alloy steel, cast iron, titanium, and titanium alloys. The stubby screw machine length profile improves rigidity over jobber-length bits, reducing deflection in CNC machining centers, turret lathes, and automatic screw machines. Its 3xD flute-to-diameter ratio keeps flutes engaged while allowing adequate chip clearance in interrupted or continuous cuts through tough workpiece materials.

Key Features

• Solid carbide construction for extended tool life in ferrous and hard metals
• 140-degree split point reduces walking and lowers entry thrust
• R-thinned, tapered web improves chip flow and center cutting performance
• Coolant-through design supports high-feed, high-speed production drilling
• Coated finish increases surface hardness and heat resistance
• Screw machine (stub) length improves rigidity and minimizes deflection

Compatibility

Designed for use in CNC machining centers, turret lathes, and automatic screw machines accepting a straight-cylindrical shank drill bit in the 0.5000 to 0.6000 inch diameter range. Intended for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloys.

Installation Notes

Install this bit in a precision drill chuck or collet rated for the shank diameter before powering the machine. Verify coolant-through passages are clear and connected before beginning high-speed operation. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material. Do not exceed the designed flute length when setting depth stops.
