180mm Turn-to-Adjust Groover, 4mm-7.5mm Range, 1-1/4 in. Bore

Description

The IG660A is a 180mm diameter adjustable groover with 1-1/4 in. bore and turn-to-adjust mechanism for variable groove widths from 4mm to 7.5mm. The turn-to-adjust design distinguishes the IG660A from the standard IG660 — groove width is changed by rotating the adjustment component rather than repositioning discrete cutter elements, providing faster groove width changes between production runs and reducing setup time in shops cutting multiple groove widths. At 180mm diameter and 1-1/4 in. bore, the IG660A fits standard production shapers. The 4mm-7.5mm range covers narrow groove work for splines, thin panel grooves, and joint tracks in solid wood and sheet goods. The turn-to-adjust mechanism is particularly useful in high-mix production where groove width changes are frequent between jobs or product variants. Confirm the adjustment is locked securely at the target groove width before starting the production run, and that spindle speed is within safe limits for a 180mm groover head.
