Osg 650013231 Screw Machine Drill Bit 3.36mm Carbide

Product Description

The OSG 650013231 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series 6500 standards, it features a 3.36 mm (0.1323 inch) diameter with a 140-degree point angle and an R-thinned point geometry that reduces thrust and improves centering on entry. The EgiAs coating provides enhanced wear resistance and heat protection during cutting. With a right-hand spiral flute and coolant-through capability, this bit handles tough, heat-generating materials without sacrificing hole quality. Licensed machinists and tooling specialists are the primary installers and users of this bit.

This drill bit is engineered for use on steel, alloy steel, cast iron, titanium, and titanium alloys. The screw machine length (stub) format keeps the bit rigid and reduces deflection, making it well suited for CNC machining centers, turret lathes, and drill presses where short tool overhang is required. The 3xD flute-to-diameter ratio supports chip evacuation in blind and through holes at moderate depths. It fits applications where tight diameter tolerances and consistent hole finish are critical.

Key Features

• Solid carbide construction for rigidity and wear life in ferrous and hard materials
• EgiAs coating for improved heat and abrasion resistance
• 140-degree point angle with R-thinned web for reduced entry thrust and accurate positioning
• Coolant-through design to manage heat in high-speed or deep-hole operations
• Straight-cylindrical shank at 4.00 mm diameter for standard collet or chuck mounting
• Screw machine (stub) length body minimizes deflection in short-reach setups

Compatibility

Designed as a direct-fit tooling option for CNC machining centers, turret lathes, and drill presses accepting a 4.00 mm straight-cylindrical shank, suitable for applications targeting steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Installation Notes

Install and remove this bit using appropriate collet chucks or drill chucks rated for the 4.00 mm shank diameter. Verify spindle runout is within tolerance before use, as carbide tooling is sensitive to lateral forces and can fracture under excessive runout or interrupted cuts. Ensure coolant lines are clear and delivering adequate flow when using the coolant-through feature. Handle carbide bits carefully during storage and changeover to avoid chipping the cutting edges.
