Indexable-insert milling cutter S836-1TM – 21 mm, internal coolant (Teknik Makina)

Indexable-insert milling cutter S836-1TM for XNKT 0604 indexable inserts, built to combine rigidity and coolant-through performance for demanding workshop milling tasks

• 21 mm cutting diameter with 20 mm shank
• Internal coolant for improved chip evacuation
• Compatible with XNKT 0604 Korloy inserts
• Robust 150 mm overall length, 40 mm cutting depth

Stable geometry for consistent metal removal

The S836-1TM tool is engineered around a 21 mm diameter body and a 20 mm shank to deliver the rigidity required for accurate pocketing and face milling. With a 150 mm overall length and a 40 mm cutting length, the design balances reach and stability to reduce chatter and maintain tolerances. The use of two cutting edges minimises cutting forces and supports steady material removal, which leads to improved surface finish and consistent dimensional results in repeated production runs.

Coolant-through design and secure insert clamping

A central benefit of this shank-mounted cutter is the internal coolant channel that delivers fluid directly to the cutting zone, supporting chip control and thermal management during prolonged cycles. The cutter accepts XNKT 0604 indexable inserts and is specified to work with Korloy inserts, giving rapid regrinding or indexing options without retooling the holder. Insert fixation is achieved with an M3x7 Torx screw, tightened with a T8 key, allowing secure clamping and quick servicing to reduce machine downtime.

Practical advantages for workshop and production environments

By combining a standardised insert type with coolant-through capability, this tool supports flexible tooling strategies and reduces inventory complexity. The adaptable holder lets job shops and industrial workshops switch grades of inserts for different materials while retaining the same mounting system. The overall package aims to shorten set-up times and improve process reliability, making the cutter a pragmatic choice for production-focused teams seeking stable milling performance.
