Conventional tap holders (those with an internal moving prism) are faulty in 2 aspects: They lose the grip to the delicate tap which hits then the concrete floor. And the time consuming fumbling (best to possess 3 hands) to assemble / change tap and holder. As I am not travelling with my thread cutting tools (storage space is not an issue) I found it very convenient to ‚equip’ each tap with it’s own holder.
Die holders are by no means better than their siblings: Dies fit to loose or too tight in the holder. The „rim“ of the holder is so slim that 2 or 3 of the 5 screws never stay in their place. To tighten them needs diligence. So I gave each die it’s own fat die holder rim.
All my 6+6 most used tap holders and their equivalent dies are stored in a wooden block. I varied diameters and lengths of the handles so that subconcience points to the right tap or die.
These tap and die holders are geometrically so simple that they are pleasing to the eyes. No dancing nor obstructing nor appearing / disappearing elements while rotating the holders with delicate fingers. A real pleasure.
