Osg 52401003 Replaceable Drill Tip 0.6563 in Dia 140 Deg

Product Description

The OSG 52401003 is a replaceable drill tip from the OSG 78PXD series, designed for use with compatible indexable drill bodies in precision metal-cutting applications. The tip measures 0.6563 inches (16.67 mm) in cutting diameter and features a 140-degree point angle with a standard point type. Constructed from solid carbide with a PVD-applied chromium (Cr) coating, it delivers consistent performance in demanding drilling operations. With a functional length of 0.1194 inches and coolant-through capability, it suits high-feed production environments where chip evacuation and thermal management are critical. It is intended for installation and replacement by machinists and tooling specialists in CNC and manual drilling setups.

This replaceable drill tip is suited for drilling steel, cast iron, and non-ferrous metals in industrial machining environments. The coolant-through design supports high-speed, deep-hole drilling operations where external coolant is insufficient. It fits Insert Seat Size 4 holders and is compatible with the OSG 78PXD indexable drill body series. Typical applications include production machining on CNC machining centers, lathes with live tooling, and drill presses used in metalworking and fabrication shops.

Key Features

• Solid carbide construction for hardness and wear resistance in metal cutting
• PVD chromium (Cr) coating for improved surface lubricity and tool life
• 140-degree point angle for reduced thrust and accurate entry on steel and cast iron
• Coolant-through design for effective chip flushing and heat management
• Helical flute geometry with regular spiral for reliable chip evacuation
• Clamp-style insert holding method for secure, repeatable tip indexing

Compatibility

Designed for use with OSG 78PXD series indexable drill bodies requiring Insert Seat Size 4. Compatible with primary workpiece materials including steel (ISO P), cast iron (ISO K), and non-ferrous metals (ISO N). ISO number for this tip is PXDH6563-PC.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle locked. Use the appropriate torque wrench and clamp hardware specified by the drill body manufacturer to seat the tip securely. Do not overtighten or use damaged seating surfaces, as this can affect runout and tip retention. Always verify tip seating and runout before initiating a new cutting cycle.
