Parting and Grooving Clamp Holder K680TM — 20 mm shank, 3 mm cutting width (Teknik Makina)

A robust Parting and Grooving Clamp Holder K680TM engineered for precise turning and grooving tasks on CNC lathes, suited to indexable inserts in the 3C ZT.D family.

• Compact 20 mm shank for standard toolposts
• Precise 3 mm cutting width for narrow grooves
• Compatible with ZCC 3C ZT.D indexable inserts
• 180 mm overall length for extended reach

Stable clamping for repeatable groove quality

The holder delivers stable clamping and reduced chatter through a rigid body and defined seating for the insert. With a 20 mm shank and a balanced 180 mm overall length, the design minimises deflection during parting and grooving operations, which directly improves surface finish and repeatability. The arrangement for the insert ensures reliable chip control and consistent engagement depth; less rework and fewer rejected parts result from the improved process stability.

Built for compatibility and quick insert changes

Compatibility with the ZCC 3C ZT.D insert family and the S20Q shank designation enables quick toolset standardisation across workshops. The clamping concept allows controlled, tool-free indexable insert changes where the insert geometry is matched to a 3 mm cutting width and a cutting height of 35 mm, so set-up times are reduced and machine uptime is increased. This straightforward integration into existing tool holders supports efficient tool management and predictable cycle times.

Practical design that reduces downtime

Engineered for everyday workshop demands, the holder weighs 0.661 kg, providing a balance between rigidity and manageable handling at the bench. The solid construction and defined seating reduce the need for frequent retightening, lowering maintenance intervals. As part of a wider tooling system, the unit supports reliable batch production and quick changeover, helping to keep production schedules on track while maintaining precision.

FAQ

What insert types fit this clamp holder? The Parting and Grooving Clamp Holder K680TM accepts 3C ZT.D indexable inserts from ZCC; the seating and clamping geometry are matched to that insert family for correct chip flow and secure fixation.

Is the holder suitable for standard toolposts on small lathes? Yes, the 20 mm shank and compact form factor of the K680TM are designed to integrate with standard toolposts and holders used in small to medium turning centres.

How does the clamping system affect tool change times? The clamping arrangement on this holder facilitates straightforward insert replacement, reducing set-up time compared with dedicated clamp designs and supporting faster tool changes during batch production.

Can this holder be used for heavy roughing cuts? The holder is optimised for parting and groove operations with a 3 mm cutting width and is intended for precise cutting and finishing. For heavy roughing, a more massive roughing toolholder would normally be recommended.

What are the key dimensional data to check before ordering? Check the 20 mm shank diameter, 180 mm overall length, cutting height 35 mm and the required insert family (3C ZT.D) to ensure compatibility with the machine and insert inventory.
