Screw-in milling head for LNMU 0303 indexable inserts (Teknik Makina) — 20 mm, internal coolant

The screw-in milling head for LNMU 0303 indexable inserts is designed for versatile milling tasks where stability and coolant supply directly at the cutting zone are essential.

• 20 mm diameter for compact milling
• Internal coolant for improved chip evacuation
• M10 screw-in connection for secure mounting
• Compatible with LNMU 0303 inserts (Tungaloy)

Consistent precision through tailored compatibility

The compact 20 mm diameter geometry delivers a stable cutting footprint while allowing access to tighter features on components. By accepting LNMU 0303 indexable inserts, the tool provides a cost-effective route to repeatable results: the proven insert format from Tungaloy offers predictable chip formation and surface finish. This compatibility reduces tooling complexity on the shop floor and simplifies inventory management, enabling reliable indexing and repeatable pocketing operations without compromise.

Improved process reliability with targeted coolant supply

Equipped with internal coolant, the head supplies lubricant and coolant directly to the cutting edge, which stabilises cutting temperatures and aids chip evacuation. That direct feed reduces thermal expansion in the cutting zone and prolongs insert life, particularly when machining alloys or interrupted cuts. Combined with the three cutting edges, the coolant arrangement helps maintain consistent metal removal rates and reduces the frequency of unscheduled tool changes, supporting higher machine availability and lower unit costs.

Secure mounting and straightforward insert changeover

A robust M10 thread and a defined thread height of 19 mm ensure the head seats securely and resists loosening under varying cutting loads. The clamp and retention are completed with a Torx T8 access and an M2.5x7 fastening screw, enabling quick and reliable insert replacement with commonly available tools. This mechanical simplicity shortens maintenance cycles and reduces operator handling time, an advantage in short-run production or mixed-batch environments where fast setup is essential.

Compact dimensions suited to workshop and production use

With a 49 mm overall length, a cutting-edge height of 30 mm and a lightweight construction of 0.061 kg, the tool balances rigidity with low mass for responsive spindle dynamics. The three-flute design provides a compromise between material removal and surface quality, making the head appropriate for finishing and light shoulder milling on a range of materials that the insert system supports. The compact form factor is especially useful in fixtures or multi-spindle arrangements where space is at a premium.
