Shaft Milling Cutter S850TM — for BOMT 1304 indexable inserts, 20 mm shank (Teknik Makina)

The Shaft Milling Cutter S850TM is a dedicated solid toolholder designed for precision sector milling using BOMT 1304 indexable inserts, suited to industrial steelworking and CNC applications.

• Compatible with BOMT 1304 indexable inserts
• 20 mm shank for secure toolholder fit
• 40 mm effective cutting length for deep cuts
• Torx clamping screw M3.5x8.5, key T10

Robust tool design for consistent cycle times

The S850TM is engineered to maintain machining stability under repetitive load, pairing a 20 mm shank with a well-balanced geometry to reduce vibration and improve surface quality. Compatibility with BOMT 1304 indexable inserts enables flexible selection of edge grades and coatings for different steels, helping to control tool life and part finish. The two-flute configuration supports efficient chip evacuation while retaining sufficient cutting edge for medium to heavy removal tasks. As a consequence, cycle times become more predictable and process control is simplified on milling centres and machining cells.

Quick clamping and fast insert replacement to minimise downtime

Insert changes are secured by a Torx M3.5x8.5 clamping screw accessed with a T10 key, allowing controlled torque and repeatable seating of the insert pocket. The holder is specified to accept inserts from Ingersoll in the BOMT 1304 form, which standardises supply and reduces inventory complexity. The tool’s modest mass (approx. 0.289 kg) keeps spindle load low while providing sufficient rigidity; this balance supports longer uninterrupted runs and reduces the frequency of balancing operations. Maintenance intervals are shortened through predictable clamping behaviour and straightforward replacement routines, contributing to higher overall equipment effectiveness.

Integrates into professional workshops and production lines

This shaft milling cutter is suitable for workshops and production environments that demand a pragmatic combination of robustness and flexibility. The dimensional set—20 mm diameter, 40 mm cutting length, 120 mm overall length and two cutting edges—is a practical choice for general steel machining and fits standard toolholders used in small to medium-sized CNC mills. Metav Werkzeuge provides the logistical and advisory support that complements the tool: a centralised supply from Emmerich acts as a quality filter for the European market, ensuring continuity of supply and consistent part performance across batches.

FAQ

What insert type fits this milling cutter?
The cutter accepts BOMT 1304 style indexable inserts; compatibility is specified for BOMT 1304 and matching Ingersoll inserts in the S850TM holder.

How is the insert secured in the holder?
Insert clamping is achieved with a Torx screw (M3.5x8.5) tightened using a T10 key to ensure repeatable seating and reliable clamping force for the S850TM.

Which shank diameter is required for the toolholder?
The tool is manufactured with a 20 mm shank diameter and is intended for holders that accept a 20 mm shank.

Is the S850TM suitable for heavy-duty milling?
The S850TM combines a 20 mm shank and a 40 mm effective cutting length with a two-flute geometry; this provides a balance of rigidity and chip evacuation suitable for many medium to heavy steel milling tasks.
