Powermatic PM1000-TKLPRK .079" Low Profile Riving Knife

Powermatic PM1000 Riving Knife For Safer Cuts

Powermatic PM1000 riving knife is a .079 inch low profile knife designed to work with the blade as you cut, so it supports controlled ripping on your saw. The riving knife rises and lowers with the blade, which keeps a very small clearance between the knife and blade, so the workpiece follows a consistent path through the cut. That rising and lowering motion helps prevent rotational kickback, because the kerf is guided as it clears the blade instead of drifting back into the teeth. The low profile knife sits just below the apex of the blade, so it remains in place when doing non-through cuts, which keeps the setup stable when changing from through cuts to stopped cuts. The 0.079 inch thickness allows the use of thinner blades, so kerf waste is reduced while maintaining guidance behind the cut.

Key Powermatic Low Profile Riving Knife Advantages

• The riving knife rises and lowers with the blade, so the blade/knife distance stays very small, keeping workpieces aligned as they pass through the cut and reducing the tendency for material to wander.
• This movement helps prevent rotational kickback by keeping the kerf from binding when it has cleared the blade, so offcuts stay behind the knife instead of rotating into the back of the blade.
• The low profile knife sits just below the apex of the blade, so it remains installed for non-through cuts and supports a consistent safety setup when switching between through cuts and grooves.
• The 0.079 inch thickness allows use of thinner blades, so you can run thin kerf blades that reduce kerf waste while the knife still tracks closely behind the cut.
• The thin kerf feature supports blades that remove less material, which can help conserve stock on repeated rips while the knife continues to control the opened kerf.

Low Profile Riving Knife Fit And Cutting Setup

The low profile riving knife is shaped to sit just below the apex of the blade, so it stays in the cutting line without projecting above the teeth, allowing non-through cuts while the kerf remains guided. Because the riving knife rises and lowers with the blade, the clearance between blade and knife stays nearly constant at different blade heights, which supports repeatable setups across thick and thin material. The 0.079 inch thickness is matched to thinner blades, so thin kerf blades track properly against the knife and maintain a guided slot behind the cut. This combination of low profile position, synchronized height movement, and thin kerf compatibility helps keep the cut controlled from entry to exit.

Using This Riving Knife In Everyday Saw Work

Where This Riving Knife Supports Cutting Tasks

This Powermatic Tools riving knife is part of the saw hardware for the PM1000 series, so it serves as the splitter-style guide directly behind the blade during ripping and similar operations. Because the riving knife rises and lowers with the blade, it stays aligned at different blade heights, so it supports both shallow and deeper cuts with the same guiding action. The low profile knife sits just below the blade apex, which means it remains in place during non-through cuts, so grooves, dados, or partial-depth rips still benefit from a guided kerf behind the blade. The 0.079 inch thickness allows the use of thinner blades, so thin kerf setups on the PM1000 still run with a properly sized riving knife tracking the opened slot.

How Design Details Reduce Binding And Rework

The way the riving knife rises and lowers with the blade keeps the blade/knife distance very small, so workpieces stay engaged with the knife immediately after leaving the teeth, which helps keep the kerf open and straight. This action helps prevent rotational kickback by keeping the kerf from binding after it has cleared the blade, so the operator spends less time correcting marks or dealing with twisted offcuts. Because the low profile knife sits just below the apex of the blade, it does not need removal for non-through cuts, so setups for stopped cuts do not disturb the riving knife alignment between jobs. The 0.079 inch thickness allows use of thinner blades that reduce kerf waste, so less material turns to sawdust while the knife continues to stabilize the cut path and limit binding in the opened slot.
