Sheartak Helical Cutterhead for Danckaert 500mm Jointer Planer Combo
The Sheartak helical cutterhead is designed for the Danckaert 500mm jointer planer combo and comes equipped with high-quality carbide cutters. Each kit includes five extra carbide inserts and five screws as spare parts.
Why Choose Sheartak Spiral Cutterheads?
Superior Surface Finish – The round-edged carbide inserts are angled for a shear-cut, producing a glassy-smooth finish, even on highly figured or soft woods.
Four Cutting Edges Per Insert – Each insert can be rotated up to three times for a fresh cutting edge, eliminating the need for sharpening.
Long-Lasting Sharpness – Carbide inserts last 50 times longer than HSS blades.
Improved Dust Extraction – The shorter, thinner chips produced by the spiral cutterhead make dust collection more efficient.
One-Year Warranty
All our cutterheads are backed by a one-year warranty from the date of purchase, covering parts and manufacturer defects. (Consumables not included.)

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.
