Transform your Accura woodworking experience with our precision-engineered spiral cutterhead collection. Designed specifically for woodworkers who demand excellence, these premium mechanical components deliver professional-grade performance that elevates every project.
Our Accura spiral cutterhead features advanced carbide insert technology that produces a true shear-cut, eliminating tear-out even on highly figured hardwoods. Each cutter head is manufactured to exacting tolerances by Sheartak Tools Ltd., ensuring consistent, glassy-smooth finishes that reduce or eliminate the need for extensive sanding.
Why Choose Accura Spiral Cutterheads?
Unlike traditional straight-knife systems, our spiral cutterhead design positions carbide inserts at strategic angles along helical grooves. This creates a staggered cutting pattern that significantly reduces noise while delivering superior surface quality. The mechanical component engineering behind each cutter head ensures optimal balance and vibration-free operation.
Each insert features four razor-sharp cutting edges, providing more than 10 times the lifespan of conventional high-speed steel blades. When an edge dulls, simply loosen the screw, rotate 90 degrees for a fresh edge, and you're back to work in minutes—no blade removal or sharpening required.
Professional Woodworking Tools for Lasting Value
Investing in an Accura spiral cutterhead means investing in the future of your workshop. These woodworking tools are precision ground to tolerances of ±0.0004" (±0.01mm), ensuring consistent cutting performance across thousands of board feet. The sintered tungsten carbide inserts resist wear while producing thinner, shorter chips that improve dust collection efficiency.
Whether you're working with exotic hardwoods, domestic lumber, or challenging grain patterns, our Accura cutter head collection delivers the performance and reliability that professional woodworkers trust. Backed by expert technical support from Sheartak Tools Ltd., you'll have the confidence to tackle any milling challenge.
Discover why woodworkers worldwide are retrofitting their machines with Accura spiral cutterhead technology. Experience smoother cuts, quieter operation, and dramatically reduced maintenance—all while achieving the flawless finish your craftsmanship deserves.
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.
