In high-precision turning and parting operations on the smallest components, many indexable inserts quickly reach their limits. Especially when machining shafts with external grooves, fuel injectors, fittings, and medical parts, micrometers determine success or scrap. For maximum precision and tool life, Tungaloy-NTK Germany offers a sleek solution: TetraMini-Cut. This high-performance tool with four cutting edges makes quick work of turning and parting – efficiently, economically, and with razor-sharp accuracy. Whether grooving on shafts, axial turning of mini-components, or separating the smallest workpieces: TetraMini-Cut from Tungaloy is a true multi-talent in a compact format. With cutting widths of up to 3.5 mm and parting operations on diameters up to 6 mm, the tool confidently machines various materials such as steel, stainless steel, and difficult-to-machine materials.
Thanks to the indexable inserts with four usable cutting edges, TetraMini-Cut combines the highest precision with productivity and efficiency. The tool impresses with its razor-sharp cutting edge positioning, which not only ensures excellent surface quality but also significantly increases process reliability – even with interrupted cuts or difficult-to-machine materials.
Interface with Intelligence – the Clever Clamping System
The centerpiece of the system is the unique 3-point clamping system: Here, the indexable cutting insert is not only precisely positioned but also securely fixed at three points – both form-fit and force-fit. The result: maximum clamping rigidity, exact repeatability of the cutting edge height, and reliable protection of unused cutting edges from damage. In short: a clean solution, cut after cut. Suitable indexable cutting inserts are available for a wide range of applications. For example, if you want to precisely machine external grooves, you can opt for the variant 60it TCG or TCP chip breakers. When it comes to accurately cutting threads in tight spaces, the TCT cutting inserts are the first choice. Even axial grooving in miniature diameters is not a problem: the TCF18 geometry also enables maximum precision here – with a groove outer diameter of just 6 mm.
Two newGrades for special requirements
Two new cutting material types expand the application possibilities of the TetraMini-Cuts for specific machining conditions. The type AH800576 is the ideal solution for high-speed machining in stable environments. A highly hard aluminum-rich coating combined with a wear-resistant carbide substrate significantly extends tool life. Especially in side cuts and other fast applications, this type showcases its strengths – bringing speed to the machining process.
The grade AH6235 is equally powerful. It was specifically developed for interrupted cuts and harsh machining conditions. A nano-coating with a high titanium content effectively suppresses crack propagation at the cutting edge, while a tough substrate ensures maximum tool life and reliability. The result: more stable processes, fewer tool changes, and noticeably reduced machining costs – even with the most challenging materials.
TetraMini-Cut - Dthe master of small things
Small parts, high demands – Tungaloy demonstrates with TetraMini-Cut how great technology can be in miniature format. Whether for precise grooving, clean parting, or challenging thread turning – the indexable inserts consistently deliver top performance. With economical four cutting edges, clever geometries for different applications, and high-performance cutting material grades, TetraMini-Cut is the ideal choice for grooving and parting operations in small dimensions.
