Parting tool holder D676TM – right-hand grooving holder with 4 mm cutting width

A compact parting tool holder D676TM designed for right-hand turning operations; suited to standard lathe setups and compatible with Korloy 4C MGM inserts for efficient parting and narrow-groove work

• Right-hand cutting direction
• 4 mm cutting width for narrow grooves
• Compatible with Korloy 4C MGM inserts
• 20 mm cutting-head width for stable support

Stable clamping for precise grooving

A robust clamping concept delivers stable clamping and repeatable results in parting and grooving tasks. The 20 mm cutting-head width and ISO 2020 shank format translate into reduced chatter and improved surface finish, which benefits cycle-time consistency on serial production runs. Built with a compact 125 mm overall length and a weight of 0.408 kg, the design keeps the centre of mass close to the toolpost, lowering dynamic loads on the lathe and helping maintain tool life and insert integrity during high-frequency operations.

Reduced tooling complexity through insert compatibility

Compatibility with Korloy 4C MGM inserts simplifies tooling management and cuts down on spare-part variety. The holder’s 4 mm cutting width is aimed at narrow groove and parting operations where precise chip control matters; using a standard insert family means faster changeovers and predictable cutting performance. For production environments that place a premium on uptime, the ability to accept widely available inserts reduces procurement overhead and shortens maintenance intervals.

Designed for efficient, right-hand machining on modern lathes

The holder supports a right-hand cutting direction and offers a maximum grooving depth of 18 mm, allowing confident engagement in routine to moderately deep parting tasks. The 125 mm overall length provides good reach without excessive overhang, while the unit’s modest mass contributes to low vibration transmission. Together these attributes help deliver consistent chip breakage and smoother operation on CNC and conventional lathes, improving throughput and lowering rejects in repetitive workflows.

FAQ

Which inserts fit this holder?
The D676TM accepts Korloy 4C MGM inserts; the compatibility enables straightforward replacement with standard Korloy parting/grooving plates.

Is the holder for right- or left-hand cutting?
This grooving holder is configured for right-hand cutting, matching the specified cutting-direction parameter for typical lathe setups.

What is the maximum grooving depth?
The maximum stech (grooving) depth for the D676TM is 18 mm, enabling confident engagement for many parting and grooving tasks.

What are the key dimensions to check for toolpost mounting?
Important mounting references are the ISO 2020 shank format and the 125 mm overall length; these determine clearance and overhang for the toolpost.

Can the holder be used for repeated production runs?
Yes — the holder’s stable clamping and compatibility with standard Korloy inserts support repeatable performance suitable for serial production.
