Grooving clamp holder K728TM — 4C insert holder with 32 mm shank by Teknik Makina

A grooving clamp holder engineered for narrow-groove and parting operations that accepts Sandvik 4C indexable inserts and fits an S32S shank standard

• Rigid 32 mm shank for stable mounting
• Compatible with Sandvik 4C indexable inserts
• 4 mm cutting width for narrow grooving
• 60 mm cutting height for deep cuts
• 250 mm overall length for extended reach

Stable interface for repeatable turning and parting

The combination of a 32 mm shank and a solid clamp design produces a stable mounting that limits vibration and improves surface finish. In practical terms, a stiffer holder reduces tool chatter and contributes directly to longer insert life and fewer rejected parts. The holder’s mass is balanced for lathe use; its measured weight supports predictable dynamics at common spindle speeds. Specified mounting dimensions allow straightforward integration into existing tool posts, enabling reliable, repeatable set-ups and shorter machine idle time.

Consistent groove geometry with indexable insert support

Designed around the Sandvik 4C insert form, the holder provides a secure seat for indexable cutting edges so that single-seat tightening delivers consistent radial and axial positioning. The 4 mm cutting width combined with a 60 mm cutting height supports both narrow grooving and moderate-depth parting, giving a predictable chip control strategy when paired with suitable insert grades. The indexable system simplifies changing edges: worn corners are rotated or replaced without refacing the holder, reducing maintenance time and supporting continuous production.

Workshop-ready reach, designation and handling

With a 250 mm overall length and an S32S ISO shank designation, the holder offers extended reach for overhang applications while maintaining a known interface to standard lathe toolposts. The unit’s design facilitates quick clamping of the insert and reliable torque transmission from clamp screw to insert seat. Identified in the range as K728TM, this grooving clamp holder is suitable where secure insert retention and predictable cutting geometry are priorities.
