Wiha 96315 Precision Hex Metric Screwdriver Set - 1.5mm x 50mm Chrome Vanadium Steel for Electronics, Jewelry & Small Appliances Repair - Professional Tool Kit for Watchmakers, Technicians & DIY Projects

I needed a second 1.5 driver to disassemble my bent helocopter feathering shaft. The hex bolts were super tight and I thought this driver would break. It didn't. These drivers are tough and fit snug in the hex bolts. The handles aren't knurelled like those aluminum ones but work well even though they're plastic. I'm pretty sure the hardened tips are magnetic too. That helps a lot.
