Over at Amazon, this 6-piece Wiha t-handle ball hex driver set is currently on sale for under $11. We ordered a set for outselves a few months ago at a similar price, and they’ve been performing reasonably well.
We’re not sure if this is a real sale or another instance of Amazon’s random low-pricing teasing, but the price has been stable for a few days.
Sizes include: 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 inch.
