Grooving Clamp Holder K642TM — 20 mm shank, 2 mm cutting width (Teknik Makina)

Grooving Clamp Holder K642TM is a lathe-mounted clamp holder engineered for accurate parting and grooving with 2C indexable inserts, offering a compact 180 mm overall length for extended reach in turning operations

• Parting toolholder for 2C inserts
• 20 mm shank for secure mounting
• 2 mm cutting width for narrow grooves
• 180 mm overall length for extended reach

Reliable rigidity for repeatable grooving quality

The holder delivers stability through a robust clamping interface and a 20 mm shank, which together reduce vibration during cutting and promote repeatable results. With a 2 mm cutting width specified for narrow-groove operations and a 40 mm cutting height, the design supports controlled chip formation and consistent edge engagement. The clamping concept is aimed at maintaining insert position under varying cutting loads; this reduces rework and improves process uptime in production environments where consistent groove dimensions are required.

Optimised for lathe setups and straightforward installation

Designed for common lathe toolposts, the toolholder accepts inserts in the 2C form factor and mates with S20Q-type shank arrangements, simplifying tool setup and inventory management. The 180 mm overall length provides additional reach without compromising stiffness, so operators benefit from both accessibility and control. Clear nominal dimensions and a compact mass of 0.444 kg mean balancing and tool-change routines remain efficient, while the simple clamp mechanism reduces setup time compared with more complex holders.

Practical compatibility and machining considerations

Material compatibility depends on the chosen insert grade and cutting parameters; the holder itself is specified for use with 2C inserts, enabling selection of carbide or coated grades according to application needs. The combination of cutting height and insert geometry allows stable engagement for slim grooves, and the secure clamping reduces the risk of insert shift during interrupted cuts. For operations requiring repeatable groove widths and tight dimensional tolerances, the holder’s geometry supports predictable machining results when paired with appropriate insert technology.

When this holder is the preferred choice

Choose this toolholder where narrow-parting or precision grooving is needed across short to medium production runs. Its compact design and standard shank format simplify integration into existing tool inventories, while the secure clamp and nominal dimensions reduce the setup variables that can affect process consistency. The holder is particularly suitable for workshops and small-batch production that require a reliable, easy-to-handle solution for parting and grooving tasks.

FAQ

Which insert shape fits this holder?
The holder is designed for 2C indexable inserts and accepts the standard insert geometry for narrow grooving and parting tasks.

What is the shank diameter and why does it matter?
The shank diameter is 20 mm; this dimension ensures a secure mount in compatible toolposts and contributes to reduced vibration during cutting.

What groove width can be produced with this holder?
The holder specifies a 2 mm cutting width, making it suitable for narrow groove and parting operations where slim kerf performance is required.

Is this holder suitable for long overhangs?
With an overall length of 180 mm, the holder offers additional reach; however, stiffness decreases with overhang, so keep the setup as rigid as possible for high-precision work.

How heavy is the toolholder and how does weight affect handling?
The mass is 0.444 kg, which supports easy handling during tool changes while maintaining enough mass to dampen minor vibrations in typical lathe setups.
