I got this to drill four holes in 1/4" 316 steel round rod (to replace a stroller axle).I didn't use a proper cutting fluid, just WD-40, and it did the job.I got a second one as a backup in case the first broke, but I didn't need to touch the backup.It'll be nice to have these around for jobs that my standard bits can't handle.Click Here to see more reviews about: Precision Twist Cobalt Steel Drill #54 135 Degree Split Point 7/8" Flute L 1 7/8" Overall Length
