Upgrade Your Wood-Mizer MP360 Planer Moulder (Upper Head) with Sheartak Helical Cutterhead – 100 Carbide Inserts
Transform your MP360’s performance with the Sheartak helical cutterhead, engineered for smoother cuts, quieter operation, and exceptional durability. Outfitted with 100 precision-ground carbide inserts, this upgrade delivers industry-leading results across the board.
Key Benefits:
Flawless Surface Finish – No Tear-Out
Each carbide insert is set at a slight angle, producing a shearing cut. The staggered configuration planes the surface in small, overlapping passes—virtually eliminating tear-out and leaving a smooth, glossy finish, even on highly figured or knotty hardwoods.
Significantly Reduced Noise
The staggered cutting action reduces the number of inserts engaging the wood at any given moment, resulting in dramatically quieter operation.
Extended Tool Life
The 15x15x2.5mm inserts are made from premium sintered tungsten carbide (Grade C3++/K10), lasting more than 10 times longer than high-speed steel. Each insert has four usable edges—rotate to a new edge as needed for continued sharpness.
Quick, Easy Maintenance
Inserts are interchangeable and precision-ground to a tolerance of +/-0.01mm (0.0004"). To replace or rotate, simply loosen the Torx screw, turn the insert 90°, and tighten. No complex setups or downtime required.
Improved Chip Management
Spiral cutterheads generate shorter, finer chips, making dust extraction more efficient and keeping your workspace cleaner.
Lower Operating Costs
Reduced sanding, no sharpening, and long-lasting inserts make this upgrade a cost-effective choice. The investment quickly pays for itself through enhanced productivity and material 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.
