"I've only used one of the three hinge drill bits once but it worked fine. I had struggled to install a couple of small hinges accurately but it was made easy with this drill bit. The drill itself tended to clog up with wood but this was easy to clean."
"Great for on fashion slotted screws which tend to have thicker shanks, but for modern screws the pilot holes are a bit too large. I used the largest one which is the only only that would centre in the standard 3" butt hinges I was using and the pilot hole was too big for standard number 4 pozidrive screws. They would be great for brass slotted screws though as the larger holes would be an advantage but who really uses those any more on regular work?"
"Very poor they did not manage two doors and broke. They also do not fit standard size hinges of three and four inch. As stated broke on the second door but to be fair the oak was as hard as iron. the spring that retains the guide snapped and when it did work the drill was constantly clogging up. Will have to bite the bullet and buy the Trend set which as a professional tradesman I know will work and last as well."
"Please have products tested and iron out problems that can be easily solved with simple changes. This product fails because a clockwise spiralled spring is used instead of an anti-clockwise spiralled spring. The spring keeps catching on the gap in the circlip and jamming the 'plunger' around the drill-bit. Either change direction of the spring or use a shoulder without a circlip. Either will solve the problem anf make an excellent product."
"Screwfix need to get some quality bit sets in , the springs keep sticking and you cant find replacement drill bits at screwfix , you have to buy a HSS drill set to get the 3 you need as replacements,,,dont waste your money"
