Oh dear...I got ripped buying these.
The drill bits are, by far, the worst i've ever purchased. At a close glance, they appear to be are poorly machined, and the grade of metal used is too soft for basic drilling applications. The drill bits can easily bend under the slightest pressure, and they have a tendency to randomly wonder around their intended target even on soft materials.Maybe I'm being picky but, I purchased some cheap Ryobe drill bits for six bucks at Home Depot. As I drove home, I marveled as to how something so cheap could be of any use...Wait, I don't even like Ryobe power tools doh!! When I tested them my jaw dropped. They made a super-clean cut without traveling off target or bending out of shape....Wow---six bucks!!I feel terrible for writing this article, but the truth must be told. I believe that Yukon Tools will eventually improve their producs and wish them the best of luck.
