Shank milling cutter S688TM by Teknik Makina – 26 mm diameter, for LNMU 0303 indexable inserts

The Shank milling cutter S688TM is a tool designed for precision and productivity in milling operations with LNMU 0303 indexable inserts, suitable for both finishing and medium roughing tasks

• 26 mm cutter diameter for stable engagement
• Compatible with LNMU 0303 indexable inserts
• 25 mm shank for robust clamping
• 200 mm overall length for deep reach

Increased throughput with fewer tool changes

The S688TM is engineered for a high material removal rate through its configuration of four cutting edges and a substantial 26 mm diameter. Using standard LNMU 0303 indexable inserts, the tool enables repeatable cutting performance while minimising downtime associated with regrinds. Indexable inserts allow rapid replacement of cutting edges without removing the holder from the spindle, which translates into measurable time savings on the shop floor. For operations seeking a balance between cost efficiency and cycle time, this cutter supports sustained production runs with consistent surface quality.

Secure clamping and reach for confident machining

A 25 mm shank provides the stiffness required for reliable clamping in standard toolholders, reducing vibration and improving dimensional stability. With a 200 mm overall length and 60 mm cutting length, the design suits components that require deeper pocketing or extended reach while keeping deflection low when used within recommended parameters. The combination of a rigid shank and defined cutting length keeps tolerances achievable in repetitive milling tasks, helping to protect workpiece integrity and reduce scrap rates.

Simple insert retention and workshop serviceability

Insert change and fastening are straightforward: the cutter uses Torx fixing with a T8 key and M2.5x7 Torx screws, ensuring quick and secure fastening of each insert. Compatibility with inserts from established manufacturers such as Tungaloy guarantees easy access to consumables across supply chains. Clear mechanical fastening reduces risk of incorrect assembly and supports predictable tool life. If further specification or matching of insert grades is required for particular materials, Metav Werkzeuge’s advisors can assist with grade selection to align performance with the application.
