AMAC woodworking machinery is known for delivering reliable performance and quality construction. Sheartak Tools Ltd. produces precision-engineered spiral cutterhead solutions that are specifically designed for compatibility with AMAC jointers, planers, and thicknessers, transforming these machines into professional-grade woodworking tools.
Each AMAC woodworking spiral cutterhead features premium carbide inserts strategically positioned along helical grooves at optimal shear angles. This advanced cutter head technology creates a true shear-cut that eliminates tear-out and delivers exceptionally smooth finishes on all wood types. As a high-quality mechanical component upgrade, our spiral cutterheads dramatically enhance the performance of your AMAC equipment.
Precision Mechanical Component Engineering
The AMAC woodworking 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 AMAC machinery. The staggered cutting pattern dramatically reduces operational noise while the premium carbide inserts provide more than 10 times the lifespan of conventional high-speed steel blades.
Maintenance of your cutter head is remarkably straightforward. When a cutting edge dulls, simply loosen the screw, rotate the insert 90 degrees to expose a fresh edge, and tighten—ready to cut again in minutes. No blade removal, no sharpening services, no extended downtime. This practical design makes these woodworking tools incredibly economical for professional operations.
Professional Woodworking Tools Performance
Sheartak Tools Ltd. manufactures every AMAC woodworking 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 across thousands of board feet. The advanced mechanical component design produces thinner, shorter chips that significantly improve dust extraction efficiency.
Whether you're retrofitting an AMAC jointer, upgrading your planer, or enhancing a thicknesser, our spiral cutterhead collection delivers the reliability and performance that professional woodworkers demand. These woodworking tools reduce ongoing maintenance requirements while elevating surface quality to professional standards, maximizing the potential of your AMAC woodworking 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.
