Reliable "MADE IN JAPAN" Quality

“MADE IN JAPAN” isn’t just a label—it’s a reflection of the quality and reliability that define Japanese craftsmanship. From design to production, every step is carried out domestically to uphold these exacting standards. This professional-grade model embodies over 50 years of expertise in automotive electrical components. With more than 80,000 sets sold worldwide, it has contributed to improved terminal extraction efficiency in automobiles and other transport equipment for over a quarter-century.

Material Selection Focused on Professional Use

The shaft is made of carbon tool steel. Compared to the previously used nickel-chromium-molybdenum steel, the new material offers optimized hardness and elasticity, allowing force to be transferred more effectively to the tip when accessing terminal lances inside connectors—greatly improving ease of use. It also boasts superior wear resistance, ensuring durability over long-term use.

What is Carbon Tool Steel?

Carbon tool steel is an alloy primarily composed of iron with carbon (0.55–1.50%), manganese (0.10–0.50%), and silicon (0.10–0.35%). Widely used in mechanical and industrial applications, it is favored for tools and blades—such as drills, files, knives, and press dies—that require both strength and toughness.

Precision Engineering Down to the Finest Detail

This tool was meticulously developed to ensure smooth and reliable extraction of terminals from both waterproof and non-waterproof connectors. Drawing on years of experience in the automotive aftermarket, we poured our full expertise into every aspect of the design—right down to the shape of the shaft tip—with an uncompromising attention to detail.
