Brazed refurbishable head system
Heads with brazed edges, resharpenable 2 to 4 times. Compatible with basic H7 tolerance requirements.
The brazed head is glued by brazing to the body; after wear, it is resharpened externally. Life limited by the thickness available for resharpening. Hanna HR® outperforms in refurbishing: 6 cycles per insert on average, without dedicated resharpening.
