Sheartak Spiral Cutterhead for SCM 2040FS Combined Thicknessing Planer
Upgrade your 2040FS Combined Thicknessing Planer with Sheartak’s high-performance spiral cutterhead, designed for exceptional surface finish, reduced noise, and extended durability.
Key Features & Benefits
✅ Precision Cutting with Shear Angle Design
Equipped with 102 carbide inserts, each featuring four indexable edges, this cutterhead is engineered for superior cutting performance. The inserts are positioned at a slight angle to the board feed, creating a shear cut that eliminates tear-out and delivers a flawless finish on softwood and highly figured hardwood.
✅ Dramatically Reduced Noise
The staggered cutting action significantly lowers operation noise, making for a quieter and more efficient woodworking experience.
✅ Long-Lasting & Easy Maintenance
Simply rotate an insert 90° when an edge becomes dull or nicked—no sharpening required! With four usable edges per insert, you’ll only need to replace them after all edges are worn, minimizing downtime and reducing costs.
✅ Less Sanding & More Efficiency
Sheartak’s spiral cutterhead reduces sanding work by up to 75%. The staggered chip removal prevents clogging at the dust hood port, leading to improved dust extraction and reduced power consumption.
✅ Fast Return on Investment
With reduced maintenance, longer-lasting inserts, and a smoother finish requiring less sanding, the Sheartak spiral cutterhead quickly pays for itself.
Spiral Cutterhead Kit Includes:
✔ High-tensile strength alloy steel cutter block
✔ 102 carbide inserts pre-installed
✔ 5 extra carbide inserts & 5 extra screws as spare parts
✔ 1 wrench for easy insert replacement
Upgrade to Sheartak’s spiral cutterhead and experience a superior, cost-effective woodworking solution!
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.
