Hand Tools Manufacturing Solutions

Precision tools are the “teeth” of the manufacturing industry, directly affecting machining accuracy, surface quality and productivity. We specialize in the manufacture of carbide/high speed steel cutting tools, medical drilling tools, precision gauges and other tooling products, providing a full range of solutions from material selection, precision molding, heat treatment, edge finishing to coating, testing and packaging to ensure that each tool meets the stringent requirements for precision and life.

Common Customer Challenges

The geometric accuracy and micro-morphology of the tool edge are difficult to control stably, affecting cutting performance and surface quality
Deformation and internal stress after heat treatment of cemented carbide/high-speed steel materials lead to a decrease in subsequent finishing yield
Blunt edge and unstable burr control affect cutting force fluctuations and workpiece surface roughness
Difficult to control coating process parameters and bond strength, and tool life and wear resistance fluctuate greatly
Tools with thin length ratios (such as slender drill bits and reamers) are prone to vibrate during finishing, and the straightness and roundness are extremely different.
Lack of standardization of tool detection and classification, making it difficult to achieve batch consistency management
