Grooving clamping holder K663TM – 20 mm shank, 3 mm cutting width (Teknik Makina)

A grooving clamping holder K663TM designed for turning and grooving applications, compatible with Korloy KGEVR‑KGMN 300 indexable inserts and standard toolholders

• Secure clamping for KGMN indexable inserts
• 20 mm shank for standard tool posts
• 3 mm cutting width for narrow groove work
• 150 mm overall length for stable reach

Precision where it matters: guaranteed insert compatibility and alignment

The holder is engineered for consistent positioning of KGEVR‑KGMN 300 style inserts, delivering repeatable geometry for groove and parting operations. With a 20 mm shank and an ISO shank designation S20M 3C, the device integrates with common turret and toolpost systems, permitting direct replacement without adapter work. The combination of precise clamping and proven insert interface reduces indexing deviation and supports high repeatability in series production.

Stable cutting performance through rigid design and measured dimensions

A compact mass of 0.37 kg and a balanced 150 mm overall length limit deflection during interrupted cuts. The 3 mm cutting width and 45 mm cutting height (insert engagement range) allow controlled chip formation in narrow grooves, while a 25 mm nominal diameter contributes to lateral stiffness. This balance of dimensions supports efficient metal removal with reduced chatter, especially on short overhangs and moderate depths of cut.

Faster set-up and predictable tool life for shop efficiency

Clamping geometry aligned to the KGMN family simplifies insert changes and shortens downtime. The S20M 3C shank designation ensures immediate recognition during tool preparation and inventory management. By using a standardised holder and compatible Korloy inserts, shops benefit from predictable tool life and fewer unforeseen adjustments, supporting steady throughput and lower process variance.

Practical suitability for workshop environments and simple maintenance

The holder’s straightforward clamping mechanism and accessible interface with KGEVR‑KGMN 300 inserts permit quick maintenance and low-complexity spare-part management. Lightweight construction eases handling during tool changes, while robust mating surfaces maintain alignment over repeated cycles. For operations requiring reliable narrow-groove work, this toolholder offers a pragmatic blend of performance and serviceability, suited to general turning shops and production lines.

FAQ

What inserts fit this holder?
The grooving clamping holder accepts KGEVR‑KGMN 300 style indexable inserts; Korloy inserts of that designation are specified for direct compatibility.

What shank size is required for installation?
The holder uses a 20 mm shank (S20M 3C), designed to fit standard toolposts and turret slots compatible with that shank diameter.

Is the holder suitable for narrow groove cutting?
Yes, the 3 mm cutting width is intended for narrow grooving and parting tasks where a slim cut width is required.

How long is the holder and how does that affect stiffness?
With an overall length of 150 mm, the holder provides a balance between reach and rigidity; its modest mass contributes to reduced deflection in short-to-medium overhang setups.

Can the same holder be used for different insert manufacturers?
The holder is specified for the KGMN family; compatibility with other manufacturers depends on exact insert geometry, but Korloy KGEVR‑KGMN 300 inserts are the intended match.
