Infinity Tools Replacement Planer Knives for DeWalt DW734

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

Tired of dull planer knives? Infinity Tools replacement knives for your DeWalt DW734 planer are a premium upgrade designed to deliver longer life, superior sharpness, and a smoother finish than OEM blades. Available in High Speed Steel (HSS) or Carbide Tipped (CPJK) versions, these knives allow you to choose the right balance of value, durability, and performance for your shop.

High Speed Steel (HSS) Knives – HSSK-039

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 consistency.
