D667TM Grooving tool clamping holder — right‑hand, 3 mm cutting width by Teknik Makina

D667TM grooving tool clamping holder for right‑hand parting and grooving, compatible with Korloy 3C MGM indexable inserts and designed for compact turning toolposts

• Right-hand cutting orientation
• 3 mm cutting width for narrow grooves
• 18 mm maximum cutting depth
• Compatible with Korloy 3C MGM inserts

Consistent cut quality for precision parting

The D667TM delivers a compact solution for controlled parting and narrow grooving tasks. With a 3 mm cutting width and a 12 mm cutting‑head width, the design focuses on stable chip formation and predictable forces, which reduces vibration and tool chatter. The result is improved surface finish and reduced rework, particularly important when batch repeatability and tight tolerances are required. The modest 0.162 kg mass contributes to low overhang and helps maintain stiffness in short‑reach applications.

Compact mounting and simplified insert changes

Engineered for efficient workflow, this clamping unit uses a 1212 shank designation for easy fitment in standard toolholders and adopts a clamping geometry that speeds up insert replacement. The holder’s overall length of 125 mm keeps the cutting edge close to the toolpost, lowering leverage and improving rigidity. Quick access to the clamping screw and a straightforward insert seat reduce downtime during changeover and help maintain high machine utilisation across recurring operations.

Broad compatibility and clear application range

The holder accepts 3C MGM style indexable inserts and is listed as compatible with Korloy plates, ensuring access to a wide range of cutting grades and chipbreaker geometries suitable for steels and general workshop materials. Its right‑hand cutting direction is optimised for conventional lathe orientations and ensures predictable chip flow. For users seeking a compact parting solution, this component is appropriate for finishing and semi‑finishing grooves where narrow slot widths and controlled depth (up to 18 mm) are required.

Reliable clamping for repeatable results

A focused clamping concept combines repeatable seating with secure screw tension to maintain cutting geometry under load. The holder’s design minimises micro‑movement at the insert seat, supporting consistent tool life and dimensional stability across runs. Where process reliability matters, the combination of short overhang, precise insert placement and robust clamping contributes to fewer scrap parts and a steadier production rhythm — a clear operational advantage for workshops and small‑batch manufacturers.

FAQ

What inserts fit this grooving clamping holder?
The holder accepts 3C MGM indexable inserts; it is compatibile with Korloy versions of that insert style for a range of cutting grades.

What is the maximum cutting depth for this tool?
Maximum cutting depth is 18 mm, suitable for most narrow grooving and parting operations that stay within short‑reach tool setups.

Which direction of cut is this holder designed for?
This unit is specified for right‑hand cutting, intended for conventional lathe orientations and predictable chip evacuation.

What shank size is required for mounting?
The holder uses a 1212 shank designation, corresponding to a compact 12 × 12 mm square interface for standard toolposts.

How does the holder contribute to repeatability?
Short overall length and positive clamping seating reduce leverage and micro‑movement at the insert, enhancing precision and consistent tool life across repeated cycles.
