4" JIS Screwdriver Bits Set #1#2#3 9 (JIS- Mix-4")

⭐ Key Features

•STOP STRIPPING SCREWS FOR GOOD: Precision-milled to strict JIS cross-point profiles, these JIS screwdriver bits lock onto Honda, Tamiya, and vintage fasteners with zero wobble and zero cam-out; finally say goodbye to rounded-off heads and ruined projects

•DUAL-GROOVE 1/4" SHANK, UNIVERSAL FIT: One shank fits both US 9mm power groove and JIS 13mm impact chucks; locks solid into any impact driver, drill, or hand wrench that takes a standard JIS screw driver; flip between tool brands instantly without swapping bits—keeping your workflow fast and interruption-free

•3X S2 STRENGTH, 10X CR-V TOUGHNESS: Forged from premium Taiwanese S2 steel with precision salt bath heat treatment; delivers 3x the strength of standard S2 and 10x the durability of ordinary Cr-V alloy. Enhanced with a zinc-calcium phosphate coating that forms a micro-porous layer to lock in anti-rust oil, providing exceptional wear and corrosion resistance. The engineered torsion zone flexes to absorb shock, so these JIS screwdriver bits handle brutal torque with minimal risk of snapping

•4-INCH (100MM) SLIM SHAFT, DEEP-REACH PRECISION: Extended 100mm slender shaft with reduced outer diameter effortlessly reaches into deep, narrow blind holes. CNC-ground tips produce exact JIS geometry for maximum surface contact; integrated magnet secures fasteners at any angle in the deepest recesses

•NO WOBBLE UNDER HIGH-SPEED IMPACT: Ordinary long bits deflect under impact driver torque, wasting power and snapping under stress. Our torsion zone features optimized geometry that minimizes deflection, delivers stable torque transfer, and slashes breakage risk in heavy-duty repairs and assembly

•5-PIECE SET FOR DIVERSE APPLICATIONS: This JIS drive screwdriver set comprises JIS #1 (4mm) for precision electronics, 2x JIS #2 (6mm) for high-frequency use scenarios, JIS #2 (5mm) slim-neck for recessed fasteners in narrow cavities, and JIS #3 (6mm) for high-torque fasteners; applications include Japanese motorcycle restoration, RC crawler assembly, Shimano/Daiwa fishing reel maintenance, and professional industrial assembly.
