Winway is a professional China Manufacturer of the Carbide Tungsten Steel Decagonal Cutter, an integral cemented-carbide cutting blade specially designed for thin copper foil slitting and slicing. Featuring a decagonal profile with ten equally distributed cutting edges, this rotary blade allows multiple edges to be used in sequence, helping reduce tool-change frequency. Its precision-ground cutting edges support smooth, clean cutting and help reduce burrs, wire-drawing and tensile deformation. Suitable for copper foil processing in lithium battery and PCB production, it is designed for continuous cutting operations.
The Carbide Tungsten Steel Decagonal Cutter is a multi-edge rotary cutting blade made of ultra-fine-grain integral cemented carbide. It features a decagonal profile, a central mounting hole and ten equally divided cutting edges. Installed on compatible slitting equipment, the blade is used for cutting, slitting and slicing thin copper foil materials.
During operation, the blade rotates at high speed to perform continuous cutting. When one cutting edge becomes worn, another edge can be brought into use by rotating the blade according to the equipment setup. This multi-edge structure helps improve edge utilization and reduce the frequency of blade replacement during production.
Substrate: Ultra-fine-grain cemented carbide (WC-Co tungsten steel). The material combines a tungsten carbide matrix with a cobalt binder phase to balance hardness, wear resistance and toughness.
WC tungsten carbide matrix: Provides high hardness and wear resistance, helping the cutting edges maintain their condition during high-speed thin-material cutting.
Cobalt (Co) binder phase: Improves material toughness and helps resist minor cutting-edge chipping during normal cutting operations.
Precision grinding: The ten cutting edges are precision-ground to achieve sharp, consistent edge geometry. Proper edge finishing helps reduce burr formation and wire-drawing when cutting thin copper foil.
Optional surface treatment: Passivation or coating treatment can be discussed according to customer requirements. The selected treatment should be confirmed based on the copper material and actual cutting conditions.
Cutting quality: The precision-ground edges are designed to produce smooth copper foil cut sections while helping reduce burrs, wire-drawing and edge curling.
Edge utilization: The decagonal structure provides ten equally distributed cutting edges. After one edge wears, another can be selected through blade rotation, increasing the number of available cutting edges compared with a single-edge blade.
Rotational stability: The equal-division structure and controlled blade dimensions help maintain stable rotation and consistent cutting conditions during continuous operation.
Chipping resistance: The ultra-fine-grain cemented-carbide substrate combines high hardness with a cobalt binder phase, helping the cutting edges resist minor impact under normal working conditions.
Ten usable cutting edges: The decagonal design provides ten independent cutting edges. Rotating the blade to use another edge after wear helps improve blade utilization and reduce tool-change downtime.
Clean copper foil cutting: Precision-ground cutting edges help reduce burrs, wire-drawing and curling during thin copper foil slitting.
Wear-resistant carbide material: The ultra-fine-grain cemented-carbide substrate offers high hardness and wear resistance for continuous cutting applications.
Stable cutting accuracy: Controlled blade dimensions and the equal-division structure help maintain rotational stability and consistent slit width.
Equipment-compatible mounting: The central mounting hole is designed for installation on compatible copper foil slitting machines. The bore size should be confirmed before ordering.
Reduced material deformation: Sharp cutting edges help reduce pulling forces during cutting, helping limit copper foil deformation and wrinkling.

Rolled copper material cutting: Suitable for high-speed segment-cutting and slitting processes involving rolled thin copper materials.
Raw material inspection: Tungsten-steel raw materials are checked for hardness and grain size. Unqualified materials are rejected before production.
In-process dimensional control: Outer diameter, thickness, inner-hole dimensions and flatness are sampled during machining to monitor dimensional consistency.
Cutting-edge inspection: All ten cutting edges are checked under a metallurgical microscope for chipping, notches and scratches.
Dimensional measurement: Finished blade outer diameter and thickness are measured with precision instruments. The inner-hole dimensions and blade flatness are also inspected.
Equal-division inspection: The distribution and machining accuracy of the ten cutting edges are checked to ensure consistent blade geometry.
On-machine trial cutting: Sample cutting may be conducted before delivery to evaluate copper foil cutting performance under the specified conditions.
Protective packaging: Each blade is individually protected to help prevent cutting-edge damage during storage and transportation.
1. Specification confirmation: The customer provides the required blade dimensions, mounting-hole specifications and equipment information.
2. Sample preparation: Trial blades are prepared according to the confirmed specifications.
3. On-machine testing: The customer installs the sample blade and conducts trial cutting under actual operating conditions.
4. Result evaluation: Feedback is collected on cutting-edge condition, burr formation and blade wear.
5. Process adjustment: Cutting-edge treatment can be reviewed and adjusted according to the trial results, where applicable.
6. Mass supply: Regular production and supply can proceed after the sample is confirmed as qualified by the customer.
Each product undergoes inspection before shipment. Free replacement is available for products confirmed to have manufacturing defects.
Technical support is provided for normal cutting applications to assist customers with reviewing cutting parameters and equipment operation.
Re-grinding services are available for worn cutting edges, subject to the remaining blade condition and dimensions, helping extend usable life and reduce replacement costs.
Disclaimer: Cutting-edge damage caused by tool collision, clamping eccentricity, foreign-matter cutting or incorrect installation is not covered by free-of-charge after-sales service.
A1: It is mainly designed for copper foil cutting, including PCB copper foil, lithium battery copper foil and conductive copper foil. Thin aluminum foil can also be evaluated through a cutting trial. It is not intended for thick metal or hard plates.
A2: Yes. The blade has ten independent cutting edges. When one edge becomes worn, the Carbide Tungsten Steel Decagonal Cutter can be rotated to bring another edge into use, helping improve cutting-edge utilization and reduce tool-change frequency.
A3: Non-standard customization is supported. Outer diameter, inner-hole size and thickness can be discussed according to equipment requirements and customer drawings.
A4: Common causes include a worn cutting edge, incorrect upper and lower blade clearance, or an unsuitable cutting speed. Check the cutting-edge condition first, then inspect the machine clearance and operating parameters.
A5: The decagonal profile provides ten equally distributed cutting edges. By rotating the blade to use another edge, operators can make better use of the available cutting edges before replacing the blade.
A6: Confirm the outer diameter, bore size, thickness and equipment mounting requirements. Correct clamping and alignment are important for stable rotation and consistent cutting results.
