Infinity Tools Replacement Planer Knives for DeWalt DW735

Available in High Speed Steel (HSS) or Carbide Tipped (CPJK)

Tired of poor performing planer knives? Infinity Tools replacement knives for your DeWalt DW735 planer are among the finest upgrades you can make to your machine. Designed for superior sharpness, durability, and finish quality, these knives outperform OEM blades and are available in two material options to match your woodworking needs: High Speed Steel (HSS) or Carbide Tipped (CPJK).

High Speed Steel (HSS) Knives – HSSK-041

Our HSS planer knives are forged from a premium high-chromium steel produced by the renowned Böhler steel mill in Austria, operating continuously since 1446. These knives are significantly thicker than the factory blades, allowing them to absorb heat more efficiently so they don’t lose their temper. They will last longer—even when planing tougher or mildly abrasive materials.

Each knife features two precision-ground cutting edges, sharpened using our proprietary ceramic-bond silicon carbide wheel for exceptional sharpness and edge consistency.

HSS Knife Specifications & Benefits:

Set of three knives

Two cutting edges

Dimensions: 13″ L × 7/8″ H × 5/64″ thick

Thicker and more rigid than OEM knives

Sharper out of the box

Longer life than stock steel knives

Ideal for general woodworking and frequent edge rotation

Carbide Tipped Knives – CPJK-041

For maximum durability and production-level performance, our carbide-tipped planer knives take your DeWalt DW735 to the next level. These knives feature a micrograin carbide cutting edge brazed to a rugged steel body, delivering greatly extended life compared to the OEM steel knives.

Designed for hardwoods, softwoods, and even abrasive wood like Teak and Cherry, carbide knives maintain a glass-smooth finish far longer than steel. While they cost more upfront, their longevity makes them the most cost-effective option for serious shops and jobsite use.

Carbide Knife Specifications & Benefits:

Set of three knives

One cutting edge

Dimensions: 13″ L × 7/8″ H × 3/32″ thick

Last many times longer than HSS knives

Transforms the DW735 into a true production planer

Produces a glass-smooth finish

Can be very lightly sharpened one time

Costs approximately 3× more than HSS, but delivers far greater lifespan

No matter which material you choose, Infinity Tools planer knives deliver precision, durability, and performance you can trust.
