About this item
- PRECISE JIS FIT HELPS PROTECT SCREW HEADS:CNC precision machined to match JIS cross-point profiles, JIS screwdriver bits provide accurate engagement with Japanese fasteners used on Honda motorcycles, Tamiya models and vintage equipment. The secure fit helps reduce cam-out, slipping and screw head damage during repair and maintenance work.
- COMPATIBLE DUAL-GROOVE SHANK: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
- ADVANCED DURABILITY PROTECTION：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.
- SLIM SHANK, DEEP-REACH PRECISION:The extended 100mm slim shaft with reduced outer diameter reaches deep, narrow and recessed screw locations that are difficult to access with standard bits. CNC precision machined tips are engineered with accurate JIS geometry to provide increased contact with screw profiles, improving torque transfer and helping reduce cam-out. The integrated magnetic tip securely holds fasteners at various working angles, providing better control in confined maintenance areas.
- 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.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
