Wide grooves are the hardest cuts a blade makes: more material per tooth, deeper engagement, and a slot wall that has to stay clean over the full width. The LIVTER 160mm slotting blade is engineered for exactly that — clearance, bite, and finish in one geometry.
Side Clearance: Why 3.6 Over 2.6 Matters
The 3.6mm kerf over a 2.6mm plate isn’t a random number — it’s side clearance. Each tooth’s carbide tip extends beyond the plate, and that extension is what keeps the steel body from rubbing the slot walls as the blade cuts. In a wide slot, friction is the enemy: it burns the wood, heats the blade, and loads the motor. The 1.0mm total clearance keeps the body free-running and the slot walls burn-free through deep passes.
Hook Rake for Chip Load
Wide kerfs produce heavy chips, and heavy chips need positive evacuation. The blade’s hook-shaped teeth with strong positive rake lift each chip off the floor of the cut and throw it into the gullet immediately. At 18 teeth, the gullets are sized for the wide-cut chip load — no recutting of chips, no packed gullets stalling the feed.
BC Grind: Engineering the Wall
The alternate-bevel grind is the finish control. Adjacent teeth are beveled in opposite directions, so the slot wall is cut by a sequence of clean shearing edges rather than a single scraping edge. The result is a wall that’s square, smooth, and ready for edging or connector hardware — the tolerance-critical part of groove work.
Keyhole Expansion Ends
Each of the three expansion slots terminates in a keyhole-shaped relief — a drilled circle that spreads the stress concentration at the slot end across a radius. Under the heat of continuous slotting, the body expands into the slots while the keyhole ends arrest any crack before it can run to the bore. Straight blade, consistent slot depth, all shift long.
