Sheartak Spiral Cutterhead for Wadkin 24" Panel Planning and Thicknessing Machine Type R.K. 557
Upgrade your Wadkin 24" Panel Planning and Thicknessing Machine Type R.K. 557 with a high-performance Sheartak spiral cutterhead equipped with a full set of carbide inserts. Each cutterhead also includes 5 extra carbide inserts and 5 screws as spare parts for your convenience.
Superior Durability and Efficiency
Optimized for Even Wear
Each carbide insert removes a small portion of material, distributing the cutting load evenly across the cutterhead and extending its overall lifespan.
Longer Service Life
Cutterheads with more inserts operate under lower load per insert, allowing them to last longer under the same cutting conditions.
High Productivity Design
Featuring full set of carbide blades, this cutterhead delivers excellent cutting efficiency and long-term cost effectiveness for demanding woodworking operations.
Exceptional Cutting Quality
Smoother Surface Finish
Sheartak spiral cutterheads produce a noticeably smoother finish compared with traditional straight-knife cutterheads.
Shear-Cut Geometry
The carbide inserts are mounted at a slight angle to the feed direction, creating a shear-cut action that significantly reduces tear-out—even on highly figured hardwoods or softwoods.
Four Cutting Edges per Insert
Each insert has four indexable cutting edges. When one edge becomes dull or damaged, simply rotate the insert to expose a new cutting edge. No sharpening or knife setting is required.
Built for Long-Term Performance
Extended Edge Life
Carbide inserts stay sharp up to 50 times longer than conventional high-speed steel (HSS) knives.
Improved Dust Extraction
The spiral cutting action produces smaller, thinner chips, allowing dust collection systems to remove chips more efficiently.
Shipping and Warranty
Fast Shipping
In-stock items ship the next business day from Waterloo, Ontario, Canada. Shipping options include Canada Post, USPS, and UPS.
Warranty
All cutterheads include a one-year warranty covering parts and manufacturing defects (consumables excluded).

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
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.
