Chamfer mill S339-1TM — chamfer cutter for TCMT 16T3 indexable inserts (34 mm, 25 mm shank)

S339-1TM is a purpose-built chamfer mill for industrial shaft tooling, optimised for repeatable chamfers using TCMT 16T3 indexable inserts.

• Chamfer mill for TCMT 16T3 inserts
• 34 mm cutting diameter for wider chamfers
• 25 mm shank for high rigidity
• Two cutting edges for smooth finishes

Enhanced rigidity for consistent chamfering

A solid toolholder connection is essential for predictable results. The 25 mm shank delivers elevated torsional stiffness, reducing chatter and dimensional variation when machining chamfers. Compatibility with TCMT 16T3 indexable inserts allows fast reconditioning of the cutting edge: worn inserts are replaced rather than the entire cutter, cutting downtime and consumable costs. The combination of a 34 mm diameter and a compact overall length provides a balance between reach and stability for many workshop setups.

Efficient cutting and reliable surface quality

Designed with two cutting edges, the cutter achieves efficient material removal while maintaining a controlled cutting force that helps to produce even chamfer profiles. A 40 mm cutting length grants sufficient engagement for stepped or multi-level chamfers, while the 100 mm overall length supports access in deeper set-ups. The modest mass (approx. 0.378 kg) contributes to smooth acceleration on CNC spindles and helps to dampen high-frequency vibration, supporting improved surface finish without complex toolpath adjustments.

Practical mounting and maintenance for production use

Secure mounting is achieved via the included Torx fastening: T15 key access and an M3.5x8.5 Torx screw ensure repeatable clamping of the insert seat, eliminating play between the insert and the body. The indexable system simplifies inventory management—only inserts and Torx screws are regularly exchanged—while the tool body remains in service, aligning with lean maintenance practices. The model is supplied as SKU S339-1TM and is suitable for integration into standard shaft-milling toolholders classified under shaft cutters.

FAQ

How are the inserts secured in this chamfer mill?
The inserts are fastened with an M3.5x8.5 Torx screw (T15) to the seat; the S339-1TM uses the standard TCMT 16T3 indexing form for straightforward insert changes.

What shank diameter and toolholder compatibility does it offer?
The tool features a 25 mm shank, suitable for standard shaft toolholders used in milling and CNC applications where a solid clamping interface is required.

What chamfer size does a 34 mm diameter support?
A 34 mm cutting diameter facilitates wider chamfers and provides stable engagement; the actual chamfer width depends on insert geometry and axial depth of cut.

How many cutting edges are fitted and what is the benefit?
The cutter uses two cutting edges, which balance material removal rate and surface finish, helping to reduce cutting forces and improve chamfer uniformity.

Is this cutter suitable for production runs with frequent insert changes?
Yes, the indexable insert system and Torx fastening are tailored for fast, repeatable insert replacement, making the S339-1TM appropriate for production environments.
