Upgrade Your DeWalt DW735 Planer with a Spiral Helical Cutterhead for Smoother Cuts
Replacing the standard straight knives on your DeWalt DW735 or DW735X thickness planer with a spiral helical cutterhead is a significant upgrade that transforms performance. This specific 13-inch cutterhead features 56 individual carbide inserts arranged in four staggered rows and comes with a pre-installed bearing for simplified installation. The included spare blades and tools make this a comprehensive upgrade kit for serious woodworkers.
Key Considerations Before Buying
- Verify compatibility with your exact DeWalt planer model (DW735 or DW735X) before purchase, as cutterheads are precision-machined for specific machines.
- Consider the 4-row, 56-insert carbide design, which provides more cutting edges than standard 3-row heads, potentially extending time between rotations and improving finish quality.
- Evaluate the value of the included accessories, like the five spare carbide inserts and two T-wrenches, which are essential for future maintenance and blade indexing.
What Our Analysts Recommend
A quality helical cutterhead for the DW735 should have precisely machined pockets to hold the carbide inserts securely, preventing chatter and tear-out. Look for products that include the necessary bearing pre-installed, as this is a critical component for smooth operation and correct alignment. The grade of the carbide inserts and the quality of the mounting hardware are key indicators of long-term durability.
