20 mm Shank Milling Cutter for LNMU 0303 Indexable Inserts – Internal Coolant, L150 mm

Shank milling cutter for LNMU 0303 indexable inserts designed for stable, repeatable milling in general machining and finishing operations

• 20 mm shank diameter for stable clamping
• Integrated internal coolant for efficient chip evacuation
• Compatible with LNMU 0303 indexable inserts
• 150 mm overall length for extended reach

Improved accuracy through a rigid shank and balanced geometry

A robust 20 mm shank and carefully balanced body deliver reduced runout and high concentricity, which translates into more consistent surface finishes and tighter tolerances during milling. The tool’s three cutting edges distribute cutting forces evenly, lowering vibration and improving tool life. For manufacturing environments where repeatability matters, this stability reduces scrap rates and rework, while also enabling more predictable feed and speed settings on CNC milling heads.

Internal coolant and chip control that protect inserts and workpieces

The integrated internal coolant supplies lubricant directly to the cutting zone, improving heat management and flushing chips away from the cutting edge. This targeted cooling reduces thermal wear on indexable tips and helps maintain cutting-edge integrity under continuous operation. As a result, replacement intervals are extended and downtime for insert changes is reduced, contributing to a more economical machining cycle and fewer interruptions on production lines.

Simplified insert changes and wide compatibility for production continuity

Compatibility with LNMU 0303 indexable inserts and endorsement for use with Tungaloy inserts make the cutter versatile across common insert grades. Fast securement via the M2.5x7 screw and access with a T8 Torx key enable swift insert changes and straightforward service routines at the machine. With a 150 mm overall length and 50 mm cutting length, the design supports deeper engagement while keeping the clamped shank as rigid as possible. The result is a practical balance between reach and stiffness that suits batch production and small-series work alike.
