"I thought I needed a 5mm drill in order to use it with some shelf supports. It would be good marketing policy for screwfix if you offered your customers the option of buying the same size drill bit in multi packs at your lower unit price! I might well have bought a multi pack instead of a single one!"
"I am a professional machinist and bought 2 of these drills after wearing down my old one until it was 1" long. Both of them snapped within 2 minutes. They are designed to snap where the flute ends, and neither of them had been sharpened properly. Very poor value for money."
