Thread milling cutter DC207TM — for S12, S14, S21, S30 and S40 indexable inserts; Ø21 mm, 20 mm shank — Teknik Makina

A Thread milling cutter DC207TM engineered for versatile thread generation in CNC machining, compatible with a wide range of indexable inserts for flexible shop-floor use

• Compatible with S12–S40 indexable inserts
• 21 mm diameter for compact threading
• 20 mm shank for secure tool holding

Minimise tooling stock while keeping capability flexible

This cutter is built around broad insert compatibility, accepting S12, S14, S21, S30 and S40 indexable inserts, which reduces the need for multiple dedicated tools and simplifies inventory management. By using standard insert sizes, the tool enables cost-efficient regrinding or replacement and fast adaptation to different thread forms. The modular nature of the system supports uninterrupted production planning and contributes to a predictable parts flow, improving overall process economy without compromising machining versatility.

Secure clamping and reliable insert retention for stable cycles

A 20 mm shank provides a robust connection to standard tool holders, improving concentricity and reducing vibration during thread milling operations. Insert fixation is secured with an M4x10 Torx screw, tightened with a T15 key, ensuring consistent clamping force and straightforward maintenance procedures. These attributes support repeatable performance over long production runs, which is especially important for operations that prioritise dimensional consistency and surface finish.

Compact diameter with practical handling for precise results

With a Ø21 mm cutting head and a total length of 94 mm, the cutter balances rigidity and accessibility for restricted or multi-axis setups. The compact diameter helps maintain tool stiffness close to the cutting zone, reducing deflection when generating threads, while the overall length keeps overhang to a minimum. In practice, this design translates into improved precision and more predictable thread geometry, making the tool suitable for demanding manufacturing tasks where tolerances and surface integrity matter.

Integration into workshop workflows and tool management

The cutter's support for common insert formats and straightforward fastenings simplifies changeover and tool pre-setting. This eases logistic planning for maintenance teams and reduces spindle downtime during insert changes. The machining strategy benefits from the cutter's geometry when combined with appropriate CAM programming; the result is efficient chip control, repeatable thread profiles and predictable cycle times — all factors that support higher throughput and less rework on the shop floor.

FAQ

Which insert sizes fit this cutter?
The cutter accepts S12, S14, S21, S30 and S40 indexable inserts, allowing flexible selection of grades and geometries for different thread requirements.

What is the shank diameter and why does it matter?
The tool has a 20 mm shank; a larger shank diameter improves clamping stability and reduces deflection for more consistent thread profiles.

How are the inserts secured?
Inserts are fastened using an M4x10 Torx screw, tightened with a T15 key, providing straightforward and reliable insert retention.

Is this cutter suitable for multi-axis CNC machines?
The cutter’s compact Ø21 mm diameter and 94 mm overall length make it well suited to multi-axis setups where limited clearance and rigidity are considerations.

Can the cutter be used for different thread forms?
Yes — by selecting appropriate indexable inserts and CAM parameters, the cutter can generate a range of thread geometries while easing shop-floor tooling logistics.
