The Harmonized Tariff Schedule (HS code) for spiral cutterheads and other woodworking tools is 8466.92.50.10.

California Proposition 65

Upgrade JET 12" jointer-planer JPT-310 with Sheartak Helical Cutterhead equipped with 56 carbide knives for the numerous benefits it provides:

A smoother finish with no tear-out due to each knife sitting at a slight angle, resulting in a shear cut. The staggered cut of the spiral cutterhead produces a much better surface finish than a single straight cut, eliminating tear-out and leaving a glossy surface on even highly figured hardwood.

Reduced noise levels as the spiral cutterhead allows a few knives to cut in a staggered pattern.

A lifespan more than 10 times longer than high-speed steel due to the use of 15x15x2.5mm inserts made of sintered tungsten carbide, which is much harder than high-speed steel. Each insert has four edges.

Easy replacement of knives as they are interchangeable and precision-ground to a tolerance of +/-0.0004" or +/-0.01mm. In just minutes, loosen the screw, rotate the knife 90° for a new edge, and tighten the insert.

Easier dust extraction due to the thinner and shorter chips produced by the spiral cutterhead.

A cost-effective solution as the spiral cutterhead produces a smooth finish, reduces or eliminates the need for sanding, and does not require sharpening. The product pays for itself in a short period of time.

Kit Includes:

✔ 1 T-25 T-handle wrench
✔ 5 additional carbide inserts
✔ 5 extra Torx screws

Sheartak Spiral Cutterhead for JET 12'' jointer-planer JPT-310 withCarbide 56 knives

I'am pleased with my own spiral for JET JPT-310, I hadn't even to set up the beds, it fitted perfectly. Here are some pics (attached). The pics of wood are interesting (this is ash) - after straight(sharp!) blades you can clearly see the tearout, no marks after spiral cutterhead

Sheartak Spiral Cutterhead for JET 12'' jointer-planer JPT-310 withCarbide 56 knives

I received my new Spiral Cutting head for my JET JPT310 machine, it arrived in good time and in perfect condition. I set about doing the installtion and I followed David Crawford's advice. After pondering on the complexities and challenges this change would bring, from the traditional 3 bladed system to the new helical head system, I eventually jumped in. First mistake was that I purchased what I thought was a good quality pair of internal circlip pliers, only to take these back and purchase a new set. Second set worked perfectly, David Crawford did warn of this exact problem he also encountered.
I was apprehensive about the work and skill required but I needed not to have worried. The change was easy and methodical, took about 1 hour.

Now for the testing, WOW, am I glad I did this upgrade. The sound difference between the old and new was astonishing. The old sounded like a jet engine starting up, not to mention the actual cutting noise, which meant your needed ear muffs, the new was amazing, you can even have a conversation with someone without having to shout, not that I would recommend this practice.
The end result, the new Sheartak Helical head is beautifully and well made, fits like a glove in my Jet thicknesser & planer, and the resulting cut is wonderful.
Thanks Mike, I am so glad I made the switch and used Sheartak, and for all your assistance.

Sheartak Spiral Cutterhead for JET 12'' jointer-planer JPT-310 withCarbide 56 knives

I have now successfully installed the spiral cutter block in my Woodfast PT310, and I am extremely pleased with the result – works really well and hardly leaves any machine marks.

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.
