26 mm shank milling cutter S686-1TM — for LNMU 0303 indexable inserts, internal coolant (Teknik Makina)

26 mm shank milling cutter S686-1TM designed for reliable indexable-insert milling in CNC operations, combining coolant-fed performance with a rigid shank and versatile cutting length

• Internal coolant for optimised tool cooling
• Compatible with LNMU 0303 indexable inserts
• 26 mm cutting diameter, 25 mm shank
• 60 mm cutting length for versatile operations

Deliver consistent production results with compatible indexable inserts

The S686-1TM is engineered around the LNMU 0303 insert system to provide a predictable machining cycle time and straightforward insert changeover. Compatibility with established insert geometries means fewer process variables and faster setup. The combination of a 26 mm cutting diameter and a 25 mm shank reduces runout sensitivity, delivering consistent radial engagement and repeatable cutter behaviour across batches. For shops aiming for stable cycle times, this configuration supports higher feed rates without sacrificing surface finish.

Maintain tool life and improve chip control through internal coolant

The tool’s internal coolant channel directs cutting fluid precisely to the insert pocket, assisting with chip evacuation and temperature control at the cutting edge. With 4 cutting edges and a 60 mm effective cutting length, the cutter balances material removal rate and edge life; operators can increase cutting parameters where the machine and workholding permit. For materials that generate heat quickly, targeted coolant flow reduces flank wear and helps maintain insert geometry for longer, lowering overall tooling cost per component.

Rigid shank and secure fastening for reliable clamping

A robust design with 150 mm overall length and a substantial shank diameter provides axial and radial stiffness, reducing vibration during machining. The tool weighs 0.61 kg, a value that contributes to a stable dynamic balance when installed in the spindle. Assembly and insert retention use a M2.5x7 Torx screw operated with a T8 Torx key, enabling quick, repeatable insert changes with minimal risk of incorrect torque. This secure clamping arrangement supports reliable operation in medium-duty finishing and light roughing applications.

Practical benefits for workshop workflows

Designed for easy integration into existing tool inventories, the cutter supports inserts from Tungaloy, simplifying procurement and spare-part stocking. The combination of internal coolant, a long cutting length and a compact shank diameter helps reduce unplanned tool changes and rework, contributing to improved uptime on multi-shift production schedules. For engineers evaluating process improvements, the tool’s predictable performance makes it suitable for both prototype runs and series production.
