Klemmhalter MTJN for TN-- Indexable Inserts — left-hand turning, MTJNL 2525 interface

The Klemmhalter MTJN for TN-- Indexable Inserts is a left-hand clamping holder designed for turning applications with TN-- 1604 indexable inserts, offering compact dimensions for tight setups

• Left-hand cutting direction
• Compatible with TN-- 1604 inserts
• Shank height 25 mm, head width 32 mm
• Overall length 150 mm, weight 0.76 kg

Precision geometry for consistent left-hand turning

The clamping holder is engineered to provide stable, repeatable clamping and predictable tool positioning during left-hand turning. Its 93° cutting angle is designed to support the intended cutting geometry, reducing setup iterations and helping to maintain concentricity in serial production. With a 25 mm shank and a compact head width of 32 mm, the toolholder fits confined toolposts while delivering the rigidity expected in industrial turning. By matching the holder to TN-- 1604 indexable inserts, machining parameters can be standardised across batches, which improves process reliability and reduces troubleshooting time.

Robust build and secure insert retention for fewer interruptions

A reliable clamping concept and the defined insert seat minimise movement under cutting forces, which directly contributes to stable surface finish and longer insert life. The holder’s mass of 0.76 kg and overall length of 150 mm balance reach and stiffness for many workshop lathes. The toolholder’s interface designation MTJNL 2525 ensures compatibility with common toolpost systems, while the M16 connection detail supports secure mounting. These mechanical traits result in fewer re‑setups and a lower risk of tool-induced rejects, benefiting production workflows that prioritise uptime and predictability.

Practical integration and application guidance

This toolholder is intended for left-hand operations and is optimised for use with TN-- 1604 plates; check insert geometry and the machine’s toolpost clearance before final installation. The holder’s compact profile makes it suitable for operations where clearance is limited, and the 93° cutting angle helps to position the insert for controlled engagement. For users planning a retrofit or expanding a turning cell, provide the SKU D334TM and include the MTJNL 2525 designation when specifying toolholders to ensure matching components are supplied. If additional technical data or compatibility checks are required, technical advice is available to confirm fitment and best practice setup.

FAQ

Which inserts fit this toolholder?
This clamping holder is specified for TN-- 1604 indexable inserts; matching the insert geometry to the holder seat ensures correct seating and clamping.

Is the holder suitable for right-hand turning?
The holder is designed for a left-hand cutting direction and should be used accordingly to maintain correct tool geometry.

What is the mounting connection size?
The holder uses an M16 connection detail for mounting and the ISO designation MTJNL 2525 for toolpost compatibility.

How does the 93° cutting angle affect use?
The 93° cutting angle positions the insert for controlled engagement and is beneficial where a slightly negative approach stabilises chip formation.

What information is required when ordering the product?
Provide the SKU D334TM, the ISO designation MTJNL 2525, and the intended insert type (TN-- 1604) to ensure the correct configuration is supplied.
