Groove cutting is the most tolerance-critical job a saw blade does — a slot 0.1mm wide of spec rejects the edging it was cut for. The LIVTER 120mm slotting blade is engineered around that: aggressive rake for clean walls, controlled kerf for exact width, and thermal management for repeatability.
Positive Rake: Why Hook Teeth Cut Cleaner Grooves
The blade’s hook-shaped teeth carry a strong positive rake angle — each tooth’s face leans into the direction of rotation. In slot cutting, that geometry matters: the tooth shears material ahead of the blade body and lifts chips into the gullet immediately, rather than crushing them against the slot wall. The payoff is visible in the cut — smooth slot walls with no burned fibers, even at production feed rates.
Controlled Kerf: The 2.0mm Commitment
The 2.0mm kerf is ground deliberately thin because groove width is the product. A narrow, consistent kerf holds slot width tolerance across the full depth of the cut and across the life of the blade, and it reduces the cutting force on the small 120mm body — keeping the panel grooving blade stable and true in deep passes.
J-Hook Expansion Slots: Stopping Cracks Before They Start
Every expansion slot on the blade terminates in a J-shaped hook. In thermal design, a plain slot end concentrates stress and invites cracks; the hook redistributes that stress around a radius, arresting any developing fracture. Four slots give the body balanced expansion under heat, so a long run of slotting doesn’t pull the blade out of flat — repeatability is what makes the blade production-worthy.
