Stechklemmhalter — parting toolholder with 25 mm head and right-hand cut by Teknik Makina

Stechklemmhalter configured as a precision parting toolholder for turning operations, compatible with Korloy 4C MGM inserts and designed for reliable right-hand cutting in standard lathe toolposts

• 25 mm cutting-head width for stable clamping
• Compatible with Korloy 4C MGM inserts
• 4 mm cutting width for precise parting
• ISO 2525 shank, 150 mm overall length

Consistent parting performance with defined geometry

The compact parting toolholder delivers repeatable cuts through a defined 25 mm cutting-head and a narrow 4 mm cutting width, features that combine to reduce cutting forces and improve surface finish. Given the right-hand cutting orientation and the ISO-compliant shank, the holder is suited to production environments requiring quick changeovers between rough and finish passes. The design supports stable insert seating and predictable chip control, which helps to maintain cycle times and reduce scrap rates in routine turning and cut-off tasks.

Fast changeovers and standardised compatibility

Interchangeability with Korloy 4C MGM inserts and the ISO 2525 shank designation simplifies tooling logistics on the shop floor. The shank identification 4C‑R MGM enables secure mounting in commonly used lathe toolposts, while the overall length of 150 mm gives an accessible reach without excessive overhang. These measured attributes minimise set-up time and support a consistent tool life plan: inventory can be standardised around the same insert family, reducing downtime for insert changes and re‑indexing.

Designed for reliability, handling and process stability

Weighing 0.727 kg, the holder balances rigidity with manageable handling during tool changes and maintenance. The maximum plunge depth of 18 mm offers defined machining limits for safe parting operations on medium-duty workpieces. Manufactured by Teknik Makina to industry specifications, the component is optimised for secure clamping and repeatable alignment, contributing to predictable process behaviour and reduced machining variance in series production.
