S40T DCKNR boring bar — DCKNR for CN--1204 indexable inserts, 40 mm shaft by Teknik Makina

The S40T DCKNR boring bar is a right-hand toolholder designed for external turning operations using CN--1204 indexable inserts, offering a balance of rigidity and accessibility for standard lathe setups.

• Right-hand cutting direction
• Compatible with CN--1204 inserts
• 40 mm shaft diameter
• 300 mm overall length

Robust design for consistent turning performance

The bar is engineered to deliver stable chip control and repeatable results in external turning. Its monolithic configuration and the specified 40 mm shaft provide increased stiffness compared with smaller shanks, reducing deflection under load. As a result, the operator benefits from improved diameter accuracy and surface finish with fewer rework cycles. The connection to CN--1204 inserts is optimised for secure seating, which helps maintain cutting geometry across batches and supports consistent cycle times on medium-duty turning operations.

Geometry tuned to cutting efficiency and insert life

The specified 75° cutting angle and 65 mm cutting height favour effective engagement for many standard turning tasks, enabling controlled chip flow and predictable cutting forces. Right-hand cutting orientation ensures compatibility with prevailing lathe setups and simplifies tool inventory management. By pairing the holder geometry with the appropriate CN--1204 grade, the setup allows for reduced insert wear and longer in-service intervals, translating into lower tooling costs per part and higher uptime on the machine.

Dimensioning and handling for workshop integration

With an outer 50 mm diameter, a 300 mm overall length and a measured weight of 1.837 kg, the tool balances reach and rigidity for common external operations. The S40T DCKNR form factor fits standard tool posts and clamping arrangements used in industrial workshops; the practical shaft dimensions facilitate secure clamping and straightforward setup. The compact mass assists in controlled handling during changeovers while maintaining sufficient inertia to resist chatter when machining medium sections.

Practical benefits for purchasing and supply chain reliability

Selecting this toolholder supports predictable lead times and easy replacement of inserts, thanks to the widespread availability of CN--1204 plates. The robust construction reduces frequency of tool changeovers and minimises downtime associated with holder-related failures. For procurement teams, the combination of a recognised ISO designation and clear dimensional data simplifies cataloguing and ensures compatibility checks can be completed quickly, aiding rapid integration into existing tool lists.

FAQ

Which indexable inserts fit this tool?
The toolholder is designed for CN--1204 indexable inserts; matching insert grades and chipbreakers should be chosen according to the workpiece material and cutting conditions.

Is the cutting direction right-hand or left-hand?
This bar is configured for right-hand cutting, suitable for standard external turning on conventional lathes.

What are the key dimensions to check for fitting?
Important values are the 40 mm shaft diameter, 50 mm overall diameter, and 300 mm overall length—verify these against the machine toolpost and clamp capacity.

Can this holder be used for heavy roughing operations?
The holder’s stiffness and geometry favour medium-duty turning; for heavy roughing, confirm machine rigidity and insert selection to avoid excessive deflection.

What is the SKU and who manufactures the product?
The item is supplied as SKU K405TM and manufactured by Teknik Makina; Metav Werkzeuge can advise on stock and delivery options.
