Stechklemmhalter D811-1TM – Parting and grooving clamping holder, left-hand, ISO 2525 by Teknik Makina

A reliable Stechklemmhalter designed for left-hand parting and grooving operations on lathes, compatible with standard MGM 4-style inserts and shank designation 2525 for straightforward toolholder integration

• Left-hand cutting direction
• Compatible with Korloy MGM 4 inserts
• 25 mm cutting head width
• ISO 2525 shank designation

Consistent clamping for accurate parting and grooving

A secure clamp is essential when performing grooving or parting operations; the D811-1TM provides stable tool retention that reduces chatter and improves surface finish. The holder’s robust clamping mechanism keeps the insert seat rigid under cutting forces, which translates into repeatable part quality and longer insert life. For operations where consistent groove widths or clean part-offs are required, predictable tool behaviour cuts rework and increases throughput.

Broad compatibility reduces tooling complexity

The design accepts MGM 4 format inserts and is specified as compatible with Korloy cutting inserts, enabling simple replacement with widely available grades. Using a common insert family makes it easier to switch grades for different materials without changing the holder, lowering inventory complexity. This interchangeability supports efficient workshop logistics and faster set-ups, especially beneficial in mixed-production environments where quick tool changeovers matter.

Optimised for left-hand cutting and safe machining

Specified for left-hand cutting, the holder is tailored to applications that require operations from the opposite direction of standard right-hand tooling. That specification helps clarify mounting and prevents misapplication. The holder’s designation 4C-L (140-600) indicates the shank range and intended diameter adaptability, and the stated max cutting diameter 600 mm provides guidance for appropriate lathe usage. Clear directionality and defined limits reduce the risk of incorrect installation and improve operator safety.

Compact dimensions that lower vibration and improve accessibility

With an overall length of 150 mm, a cutting-head width of 25 mm and a narrow insert width of 4 mm, the holder keeps overhang to a minimum and helps maintain rigidity in confined setups. The modest mass (0.667 kg) further helps in dynamic balance and makes handling during tool changes straightforward. These dimensions support closer clearance to workpiece features, simplify access in tight toolposts and assist in achieving stable cutting conditions for fine grooving tasks.

FAQ

Which inserts fit this holder best?
The Stechklemmhalter D811-1TM accepts MGM 4 inserts; Korloy MGM 4 grades are listed as compatible with this holder for standard grooving and parting tasks.

Is the holder suitable for heavy-duty parting at large diameters?
The D811-1TM is rated for a maximum cutting diameter of 600 mm; application at larger diameters should consider machine rigidity and clamping conditions.

How does left-hand cutting affect mounting?
Left-hand specification means the tool cuts when mounted for opposite rotational direction compared with right-hand tools; correct mounting of the D811-1TM prevents improper cutting forces and ensures safe operation.

What are the key dimensions to check before ordering?
Important measurements include overall length 150 mm, shank/diameter 140 mm, cutting-head width 25 mm and insert width 4 mm; these determine fit in the toolpost and compatibility with insert sizes.

Which shank series is this holder compatible with?
The holder uses the 4C-L (140-600) shank designation and corresponds to ISO 2525 sizing for integration into appropriate tool blocks.
