Four Performance Levels, Unified Quality Standards
Our product portfolio comprehensively covers all fastening scenarios, including impact bits in four performance tiers, self-locking magnetic extensions, magnetic nut sockets, rechargeable electric screwdrivers, and complete tool sets. The product line is divided into four major series: General, Pro, Ultra, and Ultra Diamond. This tiering is not merely an expansion of the product matrix, but rather a targeted product definition tailored to the diverse operational conditions encountered in the field:

General Level
General — A well-balanced entry-level solution suitable for DIY and everyday tasks

Pro Level
Pro — A professional workhorse solution designed for craftsmen performing high-frequency, continuous operations

Ultra Level
Ultra — A high-performance industrial solution designed to meet the demands of high-load, long-duration industrial use

Ultra Diamond Level
Ultra Diamond —— Flagship coated solution, suitable for frequent assembly and disassembly as well as harsh and demanding working conditions
Each product series is designed based on the actual load conditions of its corresponding application scenarios. We provide a complete range of solutions to meet various operational needs, from the General series for everyday use to the Ultra Diamond flagship series for extreme conditions.

Two Brands, One Unified Commitment to Quality
We operate two independent brands that share the same advanced manufacturing capabilities and rigorous quality standards, differing only in channel positioning and target audiences:
BITMAN—is our professional brand targeting the B2B sector. Through a network of distributors, wholesalers, hardware chains, and overseas warehouses, we serve professional technicians, field workers, and engineering contractors. This official website serves as the primary B2B hub for the BITMAN brand.
GEINXURN—is our online retail brand, targeting end consumers on international platforms; it also covers B2B operations, serving online sellers and cross-border procurement partners.
Both brands adhere to exactly the same quality and validation standards; the only differences lie in packaging solutions and market positioning.
