Stechklemmhalter — Grooving clamp holder with 40 mm shank and 3 mm cutting width (Teknik Makina)

The Stechklemmhalter is a grooving clamp holder engineered for precision parting and narrow-groove turning, suitable for indexable 3C inserts and designed to deliver stable clamping and consistent chip control in shop-floor and production environments.

• Robust 40 mm shank for stable clamping
• 3 mm cutting width for narrow grooves
• 50 mm cutting height for deep engagement
• 300 mm overall length for extended reach

Stable machining through a high-diameter shank

A substantial 40 mm shank gives the holder exceptional torsional stability, which reduces vibration during grooving and parting tasks and therefore improves surface quality. The increased rigidity translates directly into consistent tool life for the insert and fewer reworks, so cycle times remain predictable. For operations where repeatability matters, the combination of shank diameter and robust clamping design supports stable cutting conditions even under intermittent or heavy engagement.

Precise groove control with narrow cutting width

The holder’s 3 mm cutting width is tailored for narrow-groove and parting work, enabling accurate slotting while keeping material removal localised. With a 50 mm cutting height, the tool supports deeper engagement when a single, secure setup is preferred over multiple passes. The geometry and indexing for 3C inserts allow straightforward insert seating and secure clamping, which simplifies tool setup and reduces downtime during insert changes.

Reach and accessibility for longer components

An overall length of 300 mm extends reach for workpieces with limited access or for setups requiring the tool to clear fixtures and chucks. The holder’s diameter at the cutting head and the overall balance deliver confident axial stiffness at reach, maintaining cutting stability. This makes the tool suitable for batch and one-off production where accessibility and precise positioning are necessary without compromising finish or dimensional control.

Compatibility, handling and workshop integration

Designed for use with 3C indexable inserts and specified shank designations (S40T / 3C-R S229), the holder integrates smoothly into existing tool setups. The moderate mass of 2.594 kg contributes to a grounded feel during mounting while remaining manageable for ordinary toolchanges. Routine maintenance is limited to secure clamping checks and insert seat cleaning; the simple mechanical design keeps service intervals short and predictable, supporting continuous operation in a busy turning department.
