Osg 52401004 Replaceable Drill Tip 0.6875 in 140 Deg XP3425

Product Description

The OSG 52401004 is a solid carbide replaceable drill tip designed for use with OSG 78PXD series modular drill bodies. With a cutting diameter of 0.6875 inches (17.46 mm) and a 140-degree included point angle, this tip delivers consistent entry geometry and reduced thrust in demanding drilling applications. The XP3425 carbide grade is applied through a PVD process and finished with a chromium (Cr) coating to extend tool life in abrasive cutting conditions. The helical flute design and integrated coolant-through capability support chip evacuation and thermal management at the cutting zone. Seat size 5 locates the tip securely in the matching modular holder via a clamp-style insert holding method.

This replaceable drill tip is suited for production machining environments where frequent tip changes are required to maintain hole quality and cycle times. Primary workpiece materials include steel, cast iron, and non-ferrous metals, covering a broad range of typical shop and manufacturing applications. The modular design allows the carbide tip to be swapped without removing the drill body from the spindle, reducing downtime on CNC machining centers, drill presses, and similar equipment. Two helical flutes with a regular spiral configuration support balanced cutting forces across these material groups.

Key Features

• Solid carbide XP3425 grade construction with PVD-applied chromium coating for extended wear resistance
• 140-degree point angle reduces entry thrust and supports self-centering on flat and curved surfaces
• Coolant-through design channels fluid directly to the cutting edge for chip evacuation and heat control
• Seat size 5 clamp-style interface compatible with OSG 78PXD series modular drill bodies
• Two helical flutes with regular spiral for balanced chip flow in steel, cast iron, and non-ferrous metals
• ISO designation PXDH6875-PC for cross-reference identification

Compatibility

Designed for use with OSG 78PXD series modular drill bodies requiring a seat size 5 replaceable tip. ISO number PXDH6875-PC can be used for cross-reference with compatible holder systems.

Installation Notes

Replaceable drill tips of this type are seated and clamped by machinists or toolroom personnel following the drill body manufacturer torque and seating procedures. Ensure the tip seat and clamping surfaces are clean and free of chips before installation, as contamination will affect runout and tip life. Always confirm coolant-through passages are clear and the machine spindle coolant supply is active before drilling into target materials. Inspect the seat interface for wear at each tip change to maintain positioning accuracy.
