Grooving clamp holder K678TM — grooving clamp holder with 32 mm shank and 4 mm cutting width (Teknik Cutting Tools)

The Grooving clamp holder K678TM is a purpose-built grooving and parting clamping device intended for CNC turning applications, offering standardised compatibility with indexable inserts and stable toolholding for repetitive production tasks.

• ISCAR 4C insert compatibility
• 32 mm shank for stable clamping
• 4 mm cutting width for narrow grooves
• 250 mm overall length for extended reach

Consistent groove quality through engineered rigidity

The grooving clamp is engineered to deliver repeatable results in high-volume turning operations. With a 32 mm shank and a substantial mass of 1.648 kg, the holder reduces vibration and improves dimensional consistency during cut-off and grooving processes. The compact 4 mm cutting width is suited to narrow-slot requirements and fine-details in workpieces, while the design maintains chip control and insert seating accuracy. Using a holder designed for indexable inserts means faster insert changes and predictable cutting geometry, which lowers setup time and increases throughput.

Secure clamping and precise insert positioning for longer tool life

A key advantage of this clamping device is its attention to insert support: the 55 mm insert height provides a solid contact surface and reliable locking that prevents micro-movement under cutting forces. Secure seating improves surface finish and extends insert life by promoting even wear. The clamping arrangement, compatible with ISCAR 4C inserts, ensures that cutting forces are transmitted into the body of the holder rather than into the insert seat, which reduces the risk of chipping and accidental loosening during interrupted cuts. The result is a stable process that benefits both accuracy and tool economy.

Straightforward integration and workshop benefits

Specified for compatibility with common turning toolposts, the holder accepts the S32S shank designation and matches the 4C-R DGN clamping style for easy retrofitting into existing setups. The 250 mm overall length and a tip diameter of 37 mm provide reach for moderately deep grooves while keeping the centre of gravity close to the toolpost for stability. Clear, standardised dimensions simplify tool selection and inventory: one holder covers a set of 4C insert styles from ISCAR, reducing the number of special tools required at the bench and streamlining procurement and maintenance processes.

FAQ

Which insert type fits this holder?
The Grooving clamp holder K678TM accepts 4C indexable inserts and is specified for use with ISCAR 4C insert geometries to ensure correct seating and cutting geometry.

What shank size and toolpost compatibility are required?
This clamping device uses a 32 mm shank with the S32S designation and is designed for standard turning toolposts that accept that shank size.

For which operations is the holder intended?
The holder is optimised for grooving and parting operations on CNC lathes and turning centres, providing stable support for narrow-slot machining and controlled parting cuts.

How does the clamping design protect insert life?
Secure seating and the 55 mm insert-contact height minimise micro-movement and distribute cutting forces into the holder body, reducing chipping and promoting uniform insert wear.
