The engineering problem with wide grooving blades is contradiction: width wants big teeth and aggressive removal, but finished slots demand control. The LIVTER 180mm slotting blade resolves it — 36 flat-top teeth and 1.2mm of side clearance on a 5.0mm kerf.
Why 36 Teeth on a Wide Blade
Conventional wide blades drop to low tooth counts for chip room. The 36-tooth design rejects that trade-off: dense teeth divide the wide cut into small, controlled bites, which keeps each tooth’s load low enough for a clean shear — even across a 5.0mm kerf in hardwood. The flat-top grind spreads that load across the full tooth width, resisting the chipping that pointed teeth suffer on heavy cuts.
Side Clearance: The 5.0-Over-3.8 Decision
The 5.0mm kerf over a 3.8mm plate is a clearance calculation, not a coincidence. Each tooth’s carbide tip extends 0.6mm beyond the plate edge, and that extension is the blade’s freedom: the steel body never touches the slot wall, so friction, heat, and burn marks never develop — even at full groove depth. In wide slots, where the body-to-wall contact area is largest, this clearance is the difference between a clean groove and a scorched one.
J-Hook Slots and Relief Holes: Thermal Integrity
Wide cuts generate heat faster than narrow ones. The blade’s four J-shaped expansion slots give the steel room to grow radially under heat, and the drilled relief holes at each slot’s inner end stop thermal stress from turning into cracks. The body stays flat, the kerf stays consistent, and a long production run of wide slots doesn’t pull the blade out of true.
