Adendorff Machinery Mart offers high-quality equipment and a wide selection of woodworking tools across South Africa. Sheartak Tools Ltd. produces premium spiral cutterhead solutions that are specifically engineered for compatibility with Adendorff jointers, planers, and thicknessers, delivering exceptional performance for South African workshops.
Each Adendorff spiral cutterhead features precision-manufactured carbide inserts arranged along helical grooves to create a true shear-cut. This advanced cutter head technology eliminates tear-out and produces mirror-smooth finishes on all wood species. As a trusted mechanical component upgrade, our spiral cutterheads transform your existing Adendorff machinery into professional-grade woodworking tools.
Professional Mechanical Component Engineering
The Adendorff spiral cutterhead represents a significant advancement over traditional straight-knife systems. Each mechanical component is manufactured by Sheartak Tools Ltd. to exacting tolerances, ensuring seamless integration with your Adendorff equipment. The staggered cutting pattern dramatically reduces noise while the premium carbide inserts provide more than 10 times the lifespan of conventional blades.
Maintenance of your cutter head is remarkably simple. When an edge dulls, just loosen the screw, rotate the insert 90 degrees for a fresh edge, and resume work within minutes—no blade removal or sharpening required. This practical design makes these woodworking tools incredibly cost-effective for busy South African workshops.
Quality Woodworking Tools for South Africa
Sheartak Tools Ltd. manufactures every Adendorff spiral cutterhead using high-tensile strength alloy steel paired with sintered tungsten carbide inserts. Each cutter head is precision-ground to tolerances of ±0.0004" (±0.01mm), ensuring consistent cutting performance. The advanced mechanical component design produces thinner chips for improved dust extraction efficiency.
Whether you're upgrading an Adendorff jointer, planer, or thicknesser, our spiral cutterhead collection delivers the reliability and performance that South African woodworkers trust. Get in touch with us today to discover how these professional woodworking tools can transform your Adendorff machinery!
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.
