Heavy-Duty Mold & Die Manufacturers
|
Local mold factories face severe tool wear and edge breakage when trimming hardened mold steel; standard burrs cause 15% rework rate and frequent production halts for tool replacement.
|
Our cemented carbide bits and cemented carbide burrs with cemented carbide wearproof treatment reduce tool failure rate by 82% and rework rate to 2.1%. These High Hardness Rotary Burr maintain stable cutting precision, serving as reliable Premium Burr Tools and long-lasting Durable Rotary Burrs for daily mold finishing.
