Upgrade Delta DC 580 20" Planer with Sheartak Helical Cutterheads
Transform your planing experience with Sheartak spiral cutterheads and enjoy these exceptional benefits:
-
Superior Finish: Achieve a tear-out-free, flawless surface. The staggered, angled inserts create a shear-cut effect, leaving a finish smoother than a 180-grit sanding belt. Reduce your sanding workload by up to 75%.
-
Quieter Operation: The spiral design maintains constant contact with the board, using fewer knives and significantly reducing noise levels.
-
Durable Tungsten Carbide Inserts: Each cutter is made from solid tungsten carbide, offering superior hardness and longevity compared to high-speed steel blades. If an edge becomes chipped or dull, simply rotate it 90° to access a fresh, sharp edge. With four cutting edges per insert, you get four times the usage.
-
Easy Setup and Maintenance: The precision-ground, interchangeable carbide inserts are designed for quick and hassle-free replacement. Loosen the screws, rotate the insert 90°, and tighten—all in just minutes. The taper hole locking system ensures precise positioning every time.
-
Improved Dust Extraction: Smaller carbide inserts remove shorter, thinner shavings, making dust collection more efficient and effective.
-
Cost-Effective Long-Term Solution: Spiral cutterheads are more economical over time, often paying for themselves quickly through reduced maintenance and improved efficiency.
Spiral Cutterhead Kit Includes:
-
High-tensile-strength alloy steel cutter block
-
100 pre-installed carbide inserts
-
5 extra carbide inserts and 5 extra screws (free spare parts)

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.
