End mill S686TM for LNMU 0303 indexable inserts — 26 mm, 4 flutes (Teknik Makina)

A robust End mill S686TM engineered to accept LNMU 0303 indexable inserts for precision milling in workshop and small-series production environments

• 26 mm diameter for stable cutting
• Four cutting edges for smooth removal
• 25 mm shank for rigid toolholding
• Compatible with LNMU 0303 inserts

Consistent material removal for predictable cycles

The End mill S686TM combines a 26 mm diameter with four cutting edges to deliver balanced chip formation and reduced vibration. The tool’s geometry promotes repeatable chip evacuation, while the 60 mm cutting length and 150 mm overall length give the necessary reach without excessive overhang. In practice this translates into shorter cycle times and fewer surface defects, so production planners achieve more reliable throughput and reduced rework.

Secure clamping and dependable rigidity

A 25 mm shank provides a compact, stiff interface with standard holders or collets, improving axial and radial stability during milling. The insert is secured with a T8 Torx key and M2.5x7 screw, enabling repeatable clamping torque and straightforward maintenance routines. These fastening features help to minimise chatter, support consistent dimensional accuracy and extend effective tool life across continuous runs.

Fast indexable-insert handling to reduce downtime

Designed specifically for LNMU 0303 indexable inserts, the cutter allows rapid insert changes with minimal tooling, supporting lean maintenance practices. Using standardised inserts from suppliers such as Tungaloy simplifies spare parts logistics and makes tooling more predictable across machines. Faster insert swaps reduce inactive time on the machine and keep production schedules more consistent.

Suitable for workshop and small-series production

The end mill’s balanced flute design and compact dimensions suit both bench workshops and small-series production where stability and repeatability matter. The combination of multiple cutting edges and a rigid shank supports stable feed rates and predictable tool behaviour, aiding process planning. The tool weight of 0.612 kg contributes to a known dynamic response in common toolholders, helping operators to fine-tune feeds and speeds.

FAQ

Which insert type fits this cutter?
The cutter accepts LNMU 0303 indexable inserts; use of standard LNMU 0303 inserts is recommended for the best fit.

What clamping interface is required for the toolholder?
A 25 mm shank interface is specified, so holders or collets designed for a 25 mm shank are appropriate for secure clamping of this tool.

How many cutting edges are provided and what is the effect on finish?
The tool features four cutting edges; this configuration balances material removal with surface finish and generally produces steady cutting forces.

Which screw and key are used for the insert?
Insert fastening requires an M2.5x7 screw and a T8 Torx key for correct clamping and repeatable torque.

What are the main dimensions to consider when planning setups?
Key dimensions are: 26 mm diameter, 150 mm overall length and 60 mm cutting length, which determine reach and overhang for set-up planning.
