Revolutionize Your Turning Operations with PENTA Inserts
In the competitive world of precision machining, reducing cycle time and tooling costs is paramount. Our PENTA insert range is designed to replace traditional grooving inserts with a more robust and cost-effective solution. By providing five cutting edges per insert, you more than double the tool life compared to standard ISO inserts, making it a favorite among parting inserts solutions.
Unmatched Stability and Precision
The unique star-shaped geometry of the PENTA grooving insert prevents insert rotation during heavy cutting loads. This direct rim clamping system ensures high repeatability and superior surface finish. Whether you are performing shallow grooving on a Swiss-type lathe or heavy-duty parting on a standard CNC lathe, these CNC grooving inserts minimize vibration and maximize tool life.
Series Overview: 24N vs. 34N
We offer two distinct sizes to match your specific machining requirements:
-
PENTA 24N (Small & Precise): Designed for shallow depths (CDX up to 6.5mm) and narrow widths. Perfect for small parts and Swiss machining.
-
PENTA 34N (Deep & Robust): Built for deeper penetration (CDX up to 10mm). The robust body handles higher feed rates and tougher materials easily.
