Upgrade the top Head of Your Wadkin Single-End Tenoner ECA with Sheartak Helical Cutterheads
The Wadkin ECA single-end tenoner was originally equipped with a traditional dado head system, consisting of two outside cutters and multiple inside cutters of varying thicknesses. While functional, these high-speed steel (HSS) blades wear out quickly, require frequent sharpening, and involve time-consuming setups—an inconvenience that many operators dislike.
Sheartak offers a modern solution: precision-engineered helical cutterheads designed specifically for the Wadkin ECA. Each cutterhead is equipped with durable two-edge carbide inserts that are securely fastened with a wedge system for reliable horizontal cutting. In addition, a set of spur carbide inserts is strategically positioned on the sides to handle vertical cutting with ease.
This advanced design brings multiple benefits:
-
Maximum cutting efficiency – Achieve superior material removal in fewer passes.
-
Outstanding surface finish – Consistently smooth, tear-out-free results.
-
Extended tool life – Carbide inserts last up to 10 times longer than HSS blades.
-
Reduced noise – Enjoy quieter operation for a better workshop environment.
-
No resharpening required – Simply rotate or replace inserts when needed, saving time and cost.
-
Fast return on investment – Lower maintenance and longer lifespan quickly offset the upgrade cost.
With Sheartak’s helical cutting technology, your Wadkin ECA tenoner will deliver higher productivity, better quality, and lower operating costs.

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
If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.
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.
