Osg 8690560 Screw Machine Drill Bit 5.6 Mm Solid Carbide

Product Description

The OSG 8690560 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and metalworking applications. At 5.6 mm in diameter with a 140-degree point angle and R-thinned web, this bit reduces thrust force and improves centering accuracy on entry. The overall length is 82 mm (3.2283 inches), keeping the tool compact and rigid for stub-length drilling operations. Two spiral flutes with a regular helix and a 28 mm flute length provide efficient chip evacuation. Coolant-through capability makes it well suited for high-speed, production-environment drilling where heat management is critical. The straight-cylindrical shank measures 6 mm in diameter and seats securely in standard collet chucks or drill adapters.

This bit is built for professionals drilling steel, alloy steel, cast iron, titanium, and titanium alloys in machine shop, maintenance, and production environments. The screw machine length profile is commonly chosen when rigidity matters more than reach, such as CNC machining centers, drill presses, and automated production lines. The Series 6500 designation places this tool in OSG high-performance carbide drilling line. The 3xD flute-to-diameter ratio and tapered web configuration support consistent hole quality in tough ferrous and non-ferrous workpiece materials. A licensed machinist or tooling technician familiar with carbide tooling should select feeds and speeds appropriate to workpiece material and machine capability.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree point angle with R-thinned web reduces entry thrust and improves self-centering
• Coolant-through design supports high-speed production drilling and extended tool life
• Screw machine (stub) length provides maximum rigidity and minimizes deflection
• Straight-cylindrical shank compatible with standard collet and drill chuck tooling
• Coated finish for added surface hardness and lubricity during cutting

Compatibility

Rated for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloy. Fits standard collet chucks and tool holders accepting a 6 mm straight-cylindrical shank. Drill bit diameter falls within the 5.00 to 6.50 mm size range of the OSG Series 6500 solid carbide screw machine drill family.

Installation Notes

Installation and use of carbide drill bits should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank to prevent runout. Power down and lock out the machine before changing tooling. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, or dropping the tool, as chipping or fracture can result.
