Parting clamp holder K618TM – parting and grooving toolholder, 25 mm shank, 5 mm cutting width (Teknik Makina)

A robust parting clamp holder K618TM engineered for precision grooving and parting with indexable 5C MGM inserts, suitable for production and workshop lathes

• Compatible with Korloy 5C MGM inserts
• 25 mm shank diameter for rigid clamping
• 5 mm cutting width for narrow grooves
• 200 mm overall length for extended reach

Consistent groove quality through defined compatibility

The clamp-style holder is designed around industry-standard insert geometries and ISO shank references, ensuring predictable results in series production. With a 25 mm shank and an ISO designation of S25R 5C-R, the holder delivers a stable interface to the turret or toolpost, reducing deflection under load. Compatibility with 5C MGM indexable inserts — and specific support for Korloy grades — simplifies procurement and makes tool changes straightforward. For operators less familiar with insert codes: 5C MGM describes the insert form and clamping family used in narrow-grooving and parting tasks, allowing easy matching of insert geometry to groove width and material.

Rigid clamping for longer tool life and better finishes

A purposeful clamping mechanism and conservative cutter geometry improve stability during cut entry and exit, which reduces vibration and improves surface finish. The 40 mm cutting height paired with a 5 mm cutting width offers a balanced profile for controlled chip formation on typical turning operations. The toolholder’s mass distribution and a total length of 200 mm overall provide the reach required for deeper operations while maintaining stiffness. These design choices translate into longer insert life, fewer reworks and more consistent cycle times on production runs.

Practical applications and straightforward maintenance

The holder is intended for precision grooving and parting tasks on conventional and CNC lathes where narrow slots or part-off operations are required. Typical uses include component separation, internal slotting preparations and producing narrow grooves for rings or seals. Routine maintenance consists of checking clamp torque and insert seating; the clamp design permits quick insert replacement without special tooling. The combination of Korloy-compatible inserts and the holder’s standard shank sizing makes it a practical fit for mixed workbenches and machining centres where flexibility and repeatability are priorities

FAQ

What insert types fit this holder? The holder is designed for 5C MGM indexable inserts; Korloy grades labelled for 5C MGM will fit the clamping arrangement used in the K618TM.

What shank size is required for mounting? Mounting requires a toolpost or turret accepting a 25 mm shank; the K618TM uses the S25R 5C-R designation for standardisation.

Can it be used for deep grooving applications? The 200 mm overall length provides reach for deeper operations while maintaining stiffness, provided the machine setup supports the extended overhang.

How does the clamp design affect performance? The clamp-style retention reduces insert movement under load, improving surface finish and tool life by limiting vibration during engagement and parting cuts.

Is the holder suitable for CNC and manual lathes? Yes; the robust shank and standard insert family make the holder suitable for both CNC machining centres and conventional lathes where narrow grooves or parting cuts are required.
