Sheartak Helical Cutterhead for WEN JT3062 6-Inch Benchtop Jointer
The original WEN JT3062 jointer comes equipped with two straight high-speed steel (HSS) blades, which require frequent sharpening and time-consuming setup to adjust blade height. Sheartak offers a high-performance upgrade: a helical cutterhead fitted with 20 premium carbide inserts designed to dramatically improve cutting quality and reduce maintenance.
Each carbide insert features four R150 radiused cutting edges and is mounted at a slight angle to the feed direction. This angled placement creates a true shear cut that virtually eliminates tear-out and delivers a smooth, glossy finish — whether cutting with or against the grain.
Unlike traditional blades that strike the entire board width at once, the helical cutterhead engages the wood gradually in a staggered, slicing action. This not only improves surface quality but also significantly reduces noise during operation.
When an edge becomes dull or chipped, simply loosen the screw, rotate the insert 90°, and tighten it back in place — no sharpening or alignment required. Each insert offers four usable edges, meaning you only need to replace it after all four sides are worn. This minimizes downtime and maximizes efficiency.
The inserts are industry-standard 15x15x2.5mm carbide, readily available and affordably priced. Their lifespan is up to 50 times longer than HSS blades, making them a highly cost-effective solution. Thanks to the cleaner cut, sanding work is reduced by up to 75%. The helical cutterhead also consumes less power and produces shorter, finer chips, improving dust collection and preventing clogging — even with less powerful dust extractors.
Upgrade your jointer today — the investment pays for itself quickly in time, performance, and savings.

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.
