Parting and Grooving Clamp Holder — 40 mm shank, 50 mm cutting height (Teknik Makina)

A parting and grooving clamp holder for secure clamping of 4C indexable inserts in turning and CNC grooving applications.

• Secure clamping for 4C indexable inserts
• 40 mm shank for heavy-duty stability
• 50 mm cutting height for deep grooves
• Compatible with S40T shank designation

Maximised rigidity for repeatable cuts

The holder is built to reduce vibration and maintain cutting stability: its 40 mm shank combined with a 300 mm overall length and a substantial mass (3.113 kg) creates a rigid tool assembly that improves surface finish and tool life. In practice, increased mass and the robust shank dimension lower deflection during parting and grooving, which leads to more consistent dimensional results. For CNC and manual lathes where groove accuracy is critical, this rigidity translates into fewer rework cycles and predictable cycle times.

Fast, secure insert clamping with clear geometry

Designed for 4C indexable inserts, the clamp arrangement identified as 4C-R S229 provides repeatable seating and easy replacement. The holder accepts a 4 mm cutting width and a 50 mm cutting height, making it suitable for medium-depth grooving tasks. The S40T shank designation indicates the recommended tool shank standard, simplifying integration into existing tool posts or turret stations. For users unfamiliar with insert systems: indexable inserts are replaceable cutting edges that locate precisely in a pocket; secure clamping ensures the insert remains seated under cutting forces and that positioning repeatability is maintained between changes.

Workshop compatibility and operational benefits

Integration is straightforward: the holder’s 49 mm diameter and standard shank interface make it compatible with common grooving fixtures and turrets, while the 4C insert family is widely available across suppliers. The result is a practical combination of accessibility and performance that supports both small-batch shops and production lines. Beyond compatibility, the configuration reduces set-up time; clearer insert indexing and a reliable clamp reduce downtime during tool changes, supporting steady production flow and lower overall operating costs. Where process optimisation is sought, this configuration offers a pragmatic path to improved throughput.

FAQ

What insert type fits this holder?
The holder is configured for 4C indexable inserts; the clamp model is specified as 4C-R S229 to ensure correct seating and repeatability.

Which shank standard is required?
This tool uses an S40T shank designation and a 40 mm shank diameter, designed for turrets and tool posts that accept that standard.

What are the key dimensions to check before fitting?
Relevant dimensions are overall length 300 mm, diameter 49 mm, cutting height 50 mm and cutting width 4 mm; these determine clearance and depth capabilities.

Is the holder suitable for production grooving operations?
Yes, the holder’s rigidity (mass 3.113 kg and 40 mm shank) and standard insert compatibility make it suitable for repeatable production grooving and parting tasks.
