Description

The OSG Carbide 4 Flute End Mill Square, 25 mm diameter, Long Length, Center-Cutting, is a versatile general-purpose milling tool designed for a wide range of machining tasks. Its extended length and four-flute geometry deliver efficient material removal and reach, making it well-suited for milling, slotting, and profiling in deep or hard-to-reach areas. Ideal for engineers, machinists, buyers, tradespeople, hobbyists, and maintenance professionals, this end mill excels in accessing challenging workpieces while maintaining cutting efficiency and predictable results.

  • Long Length Reach: Extends your cutting reach so you can access deep pockets, complex contours, and tight spaces without sacrificing cutting performance or needing extra tools.
  • Balanced Four-Flute Design: Combines efficient material removal with stable, smooth cutting and reliable chip clearance for consistent results across a range of general milling tasks.
  • Square End with Center-Cutting Capability: Enables plunging and precise profiling in a single pass, delivering accurate starts and clean corners for milling, slotting, and contouring.

This carbide end mill is built to support steady, repeatable performance in everyday machining. Its durability helps reduce downtime from tool changes, while the center-cutting capability and extended reach improve workflow and versatility, empowering you to achieve precise, professional finishes on a variety of workpieces.
