Teknik Makina D732TM Cut-off Clamping Holder — left-hand grooving toolholder, 3 mm cutting width

A D732TM cut-off clamping holder engineered for left-hand parting and grooving operations, compatible with ISCAR 3C DGN indexable inserts and optimised for stable clamping in workshop and production environments

• Left-hand orientation for controlled parting
• 3 mm cutting width for narrow grooves
• 20 mm clamping profile for rigidity
• Compatible with ISCAR 3C DGN inserts

Stable clamping for consistent parting performance

The toolholder delivers a mechanically rigid clamping area with a 20 mm clamping height and matching 20 mm head width, which reduces vibration and improves surface finish during parting operations. With a precise 3 mm cutting width, the holder is suited to narrow grooving and finish parting where dimensional accuracy is prioritised. The compact 125 mm overall length and modest mass (approx. 0.394 kg) allow secure mounting without excessive overhang, so runout and chatter are minimised. These measurable design choices translate into fewer rejects and more predictable cycle times on lathes and turning centres.

Efficient setup and quick insert changes

Designed around established insert systems, the holder accepts 3C DGN indexable inserts from ISCAR and is identified by the ISO-style designation 2020, which simplifies ordering and toolroom logistics. The shank reference 3C-L DGN indicates the connection geometry and assists engineers in matching toolposts and adaptors. Because indexable inserts are replaceable, downtime is limited to the insert change itself; the clamping concept keeps the insert seat aligned, ensuring repeatability. The left-hand cut orientation is specified for operations that require the tool to cut when travelling in a particular direction, so process planners can integrate the holder into existing turning programmes without geometry compromises.

Practical benefits for workshop and production use

Beyond the dimensional data, the design focuses on long-term usability: a robust clamping interface for secure insert retention, predictable cutting depth up to 20 mm, and compatibility with widely available insert types. The holder’s specifications make it appropriate for medium-duty parting and grooving tasks where stability and repeatability matter more than heavy interrupted cuts. For teams assessing tool kits, the clear numeric values — cutting width 3 mm, clamping dimensions 20 mm, overall length 125 mm — enable rapid comparison and selection, reducing procurement uncertainty and integrating smoothly into tool lists and CAM setups. For technical questions about fitment or process integration, Metav Werkzeuge’s advisers are available to assist with application matching and setup tips.

FAQ

Which insert type fits this holder?
The D732TM is compatible with 3C DGN indexable inserts from ISCAR; the holder is designed to accept these inserts with secure clamping and correct seating.

What is the maximum cutting depth?
The maximum recommended cutting depth is 20 mm, as specified for the holder’s parting capability.

Is the holder left- or right-hand?
This toolholder is specified for left-hand cutting direction and is intended for applications where the cutting motion requires a left-hand orientation.

What are the key dimensions to check for mounting?
Essential dimensions are 20 mm clamping height, 20 mm head width, 125 mm overall length and a 3 mm cutting width; these determine compatibility with toolposts and setups.

Can this holder be used for heavy interrupted cuts?
The holder is optimised for stable parting and narrow grooving; heavy interrupted cuts are outside the primary design focus and should be evaluated case by case.
