Experience professional-grade precision with our DAVDEN woodworking solutions engineered for demanding applications. Our comprehensive spiral cutterhead collection delivers exceptional performance for heavy-duty planers and jointers, transforming how you achieve smooth, flawless cuts on hardwoods, softwoods, and exotic materials.
Each precision-manufactured cutter head represents the pinnacle of cutting technology designed for serious woodworkers. Our advanced helical design incorporates premium tungsten carbide inserts arranged in an optimized spiral configuration, creating superior shear-cutting action that eliminates tear-out while delivering glass-smooth finishes on even the most challenging figured woods and end-grain applications.
These heavy-duty mechanical components are built with robust construction and high-quality materials to withstand rigorous workshop demands. Designed for compatibility with 20-inch planers and jointers, our spiral cutterhead jointer solutions offer seamless upgrades that dramatically improve performance without requiring additional modifications or complex installation procedures.
The tungsten carbide inserts in these professional-grade woodworking tools maintain exceptional cutting precision up to 50 times longer than conventional high-speed steel blades. Each insert features four indexable cutting edges that rotate effortlessly when one edge dulls—eliminating expensive sharpening services, reducing downtime, and maximizing productivity in demanding production environments.
Manufactured with high-tensile alloy steel construction, premium Japanese NSK sealed bearings, and comprehensive warranty protection, our DAVDEN woodworking spiral cutterheads represent a strategic investment in workshop efficiency and output quality. Experience reduced noise levels, improved dust collection, and virtually eliminated sanding requirements while achieving professional results that exceed industry standards.
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.
