Grooving clamp holder D773TM — right-hand parting and grooving tool by Teknik Makina

The grooving clamp holder D773TM is a right-hand toolholder designed for precise parting and grooving with ISCAR 3C GRP inserts, suited to small and medium lathes where narrow cuts and stable clamping are essential.

• Right-hand toolholder for precise grooving
• Compatible with ISCAR 3C GRP inserts
• 20 mm shank and head width for stable clamping
• 3 mm cutting width for narrow parting cuts

Deliver narrow, repeatable grooves for reduced rework

The holder delivers consistent results for fine grooving and parting operations thanks to its 3 mm nominal cutting width and a maximum grooving depth of 18 mm. These measurable parameters support process control: narrow cuts reduce material waste and minimise the need for secondary finishing, while the defined maximum depth ensures safe engagement in a single pass where applicable. With a total length of 125 mm, the tool provides sufficient reach for common centre-turning setups without excessive overhang, contributing to predictable cycle times and consistent part quality.

Rigid design for vibration dampening and longer insert life

A 20 mm shank height and matching head width provide greater stiffness at the cutting zone, which limits chatter and improves surface finish. The secure clamp arrangement is engineered for stable clamping, reducing micro-movements that accelerate insert wear. The holder’s modest mass of 0.409 kg balances rigidity with manageable tool-change handling on the shop floor. As a result, toolholders of this build help extend the lifetime of indexable inserts and maintain dimensional accuracy across production batches.

Simple integration with established insert systems

Compatibility with ISCAR 3C GRP inserts and the ISO designation 2020 simplifies procurement and inventory management by allowing the use of widely available insert formats. The holder’s shank designation 3C-R GRP matches common lathe toolpost setups, enabling straightforward replacement of existing tooling. The right-hand cutting orientation is optimised for conventional turning directions; this predictable orientation makes process planning easier and reduces the chance of setup errors.

Suited to both jobbing and small-scale production

Engineered for shop-floor reliability, this clamp holder is a practical choice where precision grooves and narrow parting cuts are frequent. The combination of a compact overall length, rigid cross-section and standardised insert interface supports rapid tool swaps and straightforward maintenance routines. For facilities that aim to streamline suppliers without sacrificing capability, this holder integrates into existing workflows and contributes to steady throughput with reduced scrap rates.

FAQ

What type of inserts does this holder accept? The grooving clamp holder D773TM accepts ISCAR 3C GRP indexable inserts; the ISO reference on the holder is 2020 to match common insert formats.

Is the D773TM suitable for deep grooving operations? The holder supports a maximum grooving depth of 18 mm; for deeper cuts, reassess tool engagement and machine rigidity before proceeding.

Which cutting direction is this tool designed for? This holder is configured for right-hand cutting; the right-hand orientation is built into the clamp and head geometry.

How does the 20 mm shank dimension benefit machining? A 20 mm shank height and head width increase stiffness at the cutting zone, reducing vibration and extending insert life in production environments.

Can this holder be used in standard lathe toolposts? Yes — the shank designation 3C-R GRP and the standardised ISO 2020 interface make the holder compatible with common lathe toolpost setups and insert inventories.
