Upgrade your DeWalt DW735 13" Planer with a Sheartak Helical Cutterhead featuring 40 carbide inserts for smoother cutting, reduced tear-out, lower operating noise, and easier long-term maintenance.
This cutterhead is designed and manufactured to maintain the same cutting circle as the original OEM cutterhead, helping preserve the intended cutting geometry of the DW735.
Smoother Finish with Reduced Tear-Out
The carbide inserts are positioned at an angle along the helical pattern to create a shear-cutting action. This progressive cutting action helps reduce tear-out and produces a smooth, clean surface, including when working with figured or difficult wood.
Reduced Cutting Noise
Because only a small number of carbide inserts engage the board at any given time, the staggered cutting action helps reduce cutting noise compared with conventional straight knives.
Long Carbide Insert Life
The cutterhead uses solid tungsten carbide inserts with four usable cutting edges.
When one edge becomes dull or damaged, simply rotate the insert 90° to expose a fresh cutting edge. There is no need to sharpen an entire set of traditional planer knives.
If an insert is damaged by a foreign object such as a staple or screw, the affected insert can normally be rotated or individually replaced rather than replacing the complete set of knives.
Easy Insert Rotation and Replacement
The carbide inserts are precision manufactured to approximately ±0.0004" (±0.01mm) to provide consistent interchangeability and positioning.
When an insert becomes dull or damaged:
-
Loosen the Torx screw.
-
Rotate the insert 90° to a fresh cutting edge.
-
Clean and correctly seat the insert in the cutterhead pocket.
-
Retighten the screw.
Improved Dust Extraction
The helical cutting action produces shorter and thinner chips than conventional straight knives, helping the DW735 dust collection system handle chips more efficiently and reducing the likelihood of chip buildup.
OEM Cutting Circle
The Sheartak cutterhead is designed with the same cutting circle as the original DeWalt DW735 OEM cutterhead, allowing it to operate within the machine's original cutting geometry.
Important Installation Information
The DW735 cutterhead must pass through the bearing bore in the machine housing during installation.
For this reason, after the cutterhead has been dynamically balanced and inspected, the carbide inserts are removed before shipment. This eliminates the need for the installer to remove all of the inserts before fitting the cutterhead through the machine housing.
The 40 carbide inserts must be installed onto the cutterhead after the cutterhead has been fitted into the planer.
We recommend reading the installation manual and watching the installation video before installing the carbide inserts.
Maximum Depth of Cut
The cutterhead can be used for cuts of up to 1/8" per pass maximum, subject to the material, board width, machine condition, and normal operating limitations of the planer.
Lower Long-Term Operating Cost
A helical cutterhead can reduce sanding requirements, eliminate routine knife sharpening, simplify maintenance, and extend cutting-edge life.
Instead of sharpening or replacing an entire set of planer knives, individual carbide inserts can be rotated or replaced as needed.

Do I need to replace the original bearings?
If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase.
We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications
Do I need to to Add a Few Boxes of Carbide Inserts
We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench?
To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board.
If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of?
The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%.
In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30.
This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
