Tsunoda TP-R Ring Sleeve Crimping Tool — JIS Made in Tsubame-Sanjo Japan

Product Description

JIS C 9711 certified crimping tool for ring sleeves (1.6 x 2, Small, Medium, Large). Made in Japan and commonly required for electrician practical exams in Japan, it delivers reliable, high-accuracy crimps for professional wiring work.

A compound double-lever mechanism multiplies force to minimize hand strain, so even users with lower grip strength can achieve the required crimp force. Precision-cast dies produce crisp, consistent crimp marks, while a ratcheting completion lock prevents the handles from opening until the specified crimp depth is reached. A pre-hold function secures the sleeve without deformation for smooth wire insertion, and thick ergonomic elastomer grips stay comfortable during extended use. Each tool undergoes full-length inspection and ships with an inspection certificate for added safety assurance.
