Sheartak Spiral Cutterhead – Compatible with Wood-Mizer MP200 Planer Moulder (72 Carbide Inserts)
Upgrade your Wood-Mizer MP200 with a Sheartak spiral cutterhead and experience improved performance, cleaner cuts, and long-term savings. Precision-engineered and equipped with 72 carbide inserts, this cutterhead brings modern efficiency to classic woodworking machines.
Why Choose a Spiral Cutterhead?
Smoother Finish – No Tear-Out
Each insert is set at a slight angle to create a shear-cutting action. Combined with the staggered layout, this design planes the board in small increments, virtually eliminating tear-out and leaving a flawless, glossy finish—even on highly figured hardwoods.
Quieter Operation
Fewer knives engage the wood at any given time, reducing cutting noise significantly compared to traditional straight knives.
Exceptional Durability
Fitted with 15x15x2.5mm sintered tungsten carbide inserts, this cutterhead lasts over 10 times longer than high-speed steel. Each insert features four cutting edges, offering extended use before replacements are needed.
Fast & Easy Maintenance
Each insert is precision-ground to +/- 0.01mm (0.0004") and fully interchangeable. To rotate or replace, simply loosen the screw, turn the insert 90°, and re-tighten—quick and hassle-free.
Better Dust Extraction
The spiral cutting action produces shorter, finer chips, improving dust collection and leaving your workspace cleaner.
Cost-Effective Over Time
No sharpening, reduced sanding, and a longer lifespan make this cutterhead a smart investment. It quickly pays for itself through improved productivity and lower maintenance costs.
What's Included in the Kit:
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.
