uxcell 7mm Paper Punch Drill, Straight Shank Hollow Bit Tool, for Hole Puncher Punching Machine

Que fue lo que solicite y me llego pronto.

I used this in my drill to cut about a hundred holes in matboard for a METAR map project. Razor sharp (be careful) and works beautifully.

With the straight sides I’ve chucked this in my drill press and it works great for those times you want to have a hole in a pad or book. Works great for those occasional times you want a hole in something too thick for a punch.

The box was clearly labeled "7mm", but the paper drill inside was 5.5mm, labeled as such on its protective tube, and as measured with calipers. For unrelated reasons, I missed the return window, which is my fault... but still not impressed. uxcell usually does better than this.

I used this drill bit for putting 7mm holes in a sectional chart for a METAR map. Important to note this requires a drill with a large chuck. Be sure to dig out the debris after each hole or the bit could overheat and snap.The bit worked well for ~30 holes drilled and the map looks great because of it. Would recommend for a similar project.

Nothing much to say other than if you need to create a hole, tho will get the job done no problem.

Works like a charm in my drill press!

I used this to build a metarmap and while it worked good on the photo paper it had a hard time cutting cleanly through the cardboard. It also took a really long time for each cut. Not sure if that was my technique or an issue with the bit but was not the most impressed. At the end of the day it got the job done but wouldn’t recommend
