Review on Cabinet Hardware Jig Punch Locator - Drill Guide Adjustable Inch & Metric Scales, Aluminum Alloy With Φ5Mm Drilling Hole, Tool Cabinet With Drill Bit And Hand Marking Tool by Romas Pennington

This whole jig is functional, as advertised, for casual DIYers. But, I think it is likely not precise or durable enough for serious woodworking professionals.The plastic pieces are rough around edges, and they seem to be just regular plastic. Not the high quality hardened plastic that can stand up to more use & abuse. The included punch and the drill bit are both too small for the drilling guide.too much wiggling room for precision punching or drilling at dead center. The only saving grace is that you can use another larger drill bit from your tool bag to do the job.If you don't need or want to pay more for precision or durability, this product should work for you.
