DCT Metric Drill Bit Guide Centering Punch 8-Piece Center Drilling Set Kit – 4mm to 12mm Bushings, Locating Pin, & Guide

Intension was good, but since the holder is made of thin plastic which still somewhat flexible, it is very hard to keep drill bit steady while drill is running. Only working if the subject you are making holes is on the floor.(I was trying to drill on the wall and the socket keeps falling off the holder while drilling.) Due to the depth of the socket and the holder, drill bit gets into the subject only about less than an inch deep. I have 1/2 inch sheetrock and 2"x4" stud to drill where the stud didn't get drilled much.

Great tools, but metric drill bits are still a novelty in the USA.Wish they would make an SAE set!

Absolutely amazing jig, especially for the price! Very high quality and easy to use. The only complain is about it's cardboard holder box, which is next to useless, but if you're organized enough it should not be a problem

Well... it do the job. But.. bits come out when drilling. You have to use some clamp to hold the plastic base. it always try to swing. Not super accuracy with position.

I requested the metric version of the product and it fits my 8,10,12 mm bits which I use in Do it yourself hardware application and fixing stuff around the house. using this tool with clamps and vise will get the job done, very creative and neat. The only thing I wished is that it came with plastic case instead of the carton case for carrying around.

easy to use ...but not so easy to use on the edge or end of narrow materialIt appears to be well made and a well thought out design.

Hubby likes them a lot.

The product is well made but lacks the center punch. Illustratio n is deceiving. Other than thatit is a good guide.T
