Stechklemmhalter – Grooving tool holder, right-hand, Ø50×150 mm (Teknik Makina)

Stechklemmhalter is a purpose-built grooving and parting clamp holder for lathe operations, optimised for right-hand cutting and compatible with Korloy MGM 4 indexable inserts.

• Right-hand cutting for clean parting
• Compatible with Korloy MGM 4 inserts
• 25 mm cutting head for secure support
• Ø50 mm shank, 150 mm overall length

Consistent parting and grooving for productive turning

The holder delivers predictable results thanks to a rigid Ø50 mm shank and a 150 mm overall length, which reduce deflection during cut-off and narrow-grooving tasks. The comparatively compact geometry concentrates stiffness at the tool centre, improving surface finish and minimising chatter when using MGM 4 indexable inserts. For machinists seeking steady repeatability, the design offers a balance between accessibility to the workpiece and the support needed for stable metal removal.

Fast setup and reliable insert clamping to save machine time

Fitted for Korloy-compatible MGM 4 inserts, the clamping system simplifies tool changes and secures cutting edges with repeatable seating. The ISO 2525 designation and supplied bar reference 4C-R (50-60) make it straightforward to confirm compatibility with existing tool posts and boring bars. Quick insert replacement reduces downtime, while the positive clamping eliminates micro-movements that can cause premature edge wear—an advantage for batch production and mixed-series work.

Optimised geometry for narrow grooves and controlled chip evacuation

A 25 mm cutting head width and a 4 mm cutting width at the insert provide the profile required for tight-groove machining and precision parting. The tool accepts a maximum effective cutting diameter of 60 mm and allows a maximum grooving depth of 20 mm, enabling a range of internal and external operations without overextending the tool. The measured 45 mm cutting height and a 25 mm cutting engagement length support correct insert positioning and consistent chip formation, which helps maintain tool life and process stability.

Workshop-grade build for everyday robustness

Weighing approximately 0.704 kg, the holder is light enough for easy handling yet substantial enough to dampen vibration at the cutting zone. The construction suits general workshop demands where durability and straightforward maintenance are priorities. The part’s compatibility with widely available Korloy inserts supports a cost-effective consumable strategy, while the design reduces the need for frequent readjustment—benefits that translate into higher throughput on the shop floor.

FAQ

Which insert type fits this holder?

The holder accepts MGM 4 indexable inserts; it is compatible with Korloy MGM 4 geometries and insert seatings for secure clamping.

Is the tool suitable for internal grooving as well as external parting?

Yes, the grooving clamp holder is designed for both narrow internal grooves and external parting operations within its maximum grooving depth of 20 mm.

What are the key dimensions to check for lathe compatibility?

Check the Ø50 mm shank and 150 mm overall length, along with the ISO 2525 interface and the 4 mm insert cutting width for correct alignment with the tool post.

Does the tool support left-hand cutting?

This model is configured for right-hand cutting; mirror or left-hand variants should be selected where that cutting direction is required.

How does the clamping design affect repeatability?

The positive clamping and ISO-compliant seating provide repeatable insert positioning, reducing setup time and ensuring consistent cutting geometry across replacements.
