POWERMATIC 1791793 PM1000-TKLPRK: .079" Low Profile Riving Knife

The riving knife rises and lowers with the blade, thus maintaining very small clearance between itself and the blade. This helps prevent rotational kickback, by keeping the kerf from binding when it has cleared the blade. The low profile knife sits just below the apex of the blade, and doesnÕt require removal when doing non-through cuts. And the thin kerf feature allows the use of thinner blades to reduce kerf waste.
Features and Benefits:
Rises and lowers with the blade, thus maintaining blade/knife distance
Helps prevent binding and kickback
Remains installed for non-through cuts
The 0.079 inch thickness allows use of thinner blades for less kerf waste
