Grooving clamping holder K708TM — 25 mm shank, 4 mm cutting width (Teknik Makina)

A Grooving clamping holder K708TM designed for precision grooving and parting operations with 4C indexable inserts in turning applications.

• 25 mm shank diameter for stable clamping
• 4 mm cutting width for precise grooving
• Compatible with ISCAR 4C indexable inserts
• 200 mm overall length for deep cuts

Consistent clamping and machining accuracy for series production

The K708TM toolholder is built around a 25 mm shank, which provides the rigidity required for repeatable grooving and parting operations. With a 4 mm cutting width and a cutting height of 35 mm, the holder is dimensioned to support predictable chip formation and maintain tool geometry under load. The design reduces vibration and permits stable cutting forces, which leads to fewer rejects in batch production and less frequent rework. Rigidity is delivered through solid construction and a secure clamping interface, so setup tolerance is minimised and process stability is enhanced.

Broad compatibility reduces setup time and simplifies tooling

Designed for use with 4C indexable inserts, the holder accepts cutting elements from leading manufacturers — notably ISCAR — allowing standardisation across tooling inventories. The mounting conforms to the S25R shank designation and is compatible with the 4C-R GRP holder rod configuration, enabling direct replacement in many established tool chains. This compatibility shortens changeover times and lowers tooling complexity, as the same insert types can be used for multiple part families. The result is a streamlined workflow and fewer tooling SKUs to manage.

Workbench reach and operational benefits for everyday workshop use

With a 200 mm overall length and a nominal diameter of 32 mm, the holder offers the reach needed for deeper grooving while maintaining control and balance; the unit’s mass of 0.81 kg supports controlled inertia without excessive overhang. The clamp geometry is optimised for repeatable seating of indexable inserts, which helps to extend insert life and reduce downtime related to repositioning. For maintenance-oriented workshops and production shops alike, the holder delivers a clear productivity advantage through reduced interruptions and consistent part quality.

FAQ

Which insert types fit this clamping holder?
The holder accepts 4C indexable inserts; the Grooving clamping holder K708TM is specifically prepared for these inserts and is compatible with ISCAR 4C variants.

What are the key mounting specifications?
Mounting follows the S25R shank designation and the holder is designed to be used with a 4C-R GRP holder rod; the K708TM therefore integrates with standard S25R setups.

What cutting width and height are supported?
The toolholder provides a 4 mm cutting width and 35 mm cutting height, dimensions that are suited to precision grooving and narrow slotting tasks.

Is the holder suitable for deep grooving applications?
With a 200 mm overall length and a 32 mm diameter, the K708TM offers sufficient reach for deeper grooves while maintaining stability and control during machining.

How heavy is the unit and what does that mean in practice?
The unit weighs 0.81 kg; this mass contributes to stable cutting dynamics without imposing excessive overhang, helping to maintain surface finish and tool life.
