Iscar 2550073 Indexable Grooving Blade Right Hand Hfai

Product Description

The ISCAR 2550073 is an indexable grooving blade designed for precision grooving, parting, and turning operations on CNC lathes and machining centers. Built to HFAI blade style in the Heliface series, it accepts HFPR/L inserts and delivers a minimum groove width of 0.1575 inches (4.00 mm). The blade stands 1.26 inches high with an overall length of 2.6378 inches and a blade width of 0.2040 inches. It is right-hand cutting orientation. Maximum depth of cut reaches 0.9843 inches (25.00 mm). Machinists and toolroom technicians working on precision turning applications will find this blade suited for high-accuracy grooving work requiring consistent insert indexing.

This blade is applied in grooving, parting, and turning operations on workpieces ranging from 2.3622 inches (60.00 mm) minimum diameter up to 2.9528 inches (75.00 mm) maximum diameter. It is suited for use in production turning environments, job shops, and maintenance machining where repeatable groove geometry is required. The HFAI blade style and Heliface series designation indicate compatibility with the corresponding ISCAR insert system. Right-hand cutting direction makes it appropriate for conventional lathe setups where the tool advances from right to left.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and all energy sources are locked out before mounting or adjusting the blade holder. Secure the blade in the appropriate tool block or holder per the machine tool manufacturer guidelines before indexing or replacing inserts. Verify insert seating and clamping torque using calibrated tooling per shop standards before resuming cutting operations.
