Gordon R Posted November 27, 2017 Report Share Posted November 27, 2017 Mate bought a drill bit set - see photo. In the top left are two plastic tubes - about an inch long. Asked where he bought them from just what they were - hadn't a clue. Internal size is about 8mm and they appear to have a spring inside.

walshie Posted November 27, 2017 Report Share Posted November 27, 2017 They're for holding screws onto the end of the screwdriver bit to save using your hand. Quote Link to comment Share on other sites More sharing options...

Gordon R Posted November 27, 2017 Author Report Share Posted November 27, 2017 Struggling to see how that would work. If you used the tube, you would have to remove it before starting screwing. If they are just for placing the screw on the bit, the screw would stay inside the tube, because of the spring. Quote Link to comment Share on other sites More sharing options...
walshie Posted November 27, 2017 Report Share Posted November 27, 2017 (edited) I've got 2 of them in my drill bit set. I've never used them but I believe they are for screwing plasterboard. Just a way to make a 48 piece drill bit set a 50 piece set IMO. They are labelled as "plastic finders" in my set.

Yellow Bear Posted November 27, 2017 Report Share Posted November 27, 2017 would this be it?? It's for driving slotted screws. Slip the screw finder onto the shaft of your driver, with the slotted bit inside the screw finder. The sleeve centers the bit onto the heads of slotted screws, preventing the bit from slipping out of the slot and making driving them easier.

grrclark Posted November 28, 2017 Report Share Posted November 28, 2017 I believe the universal consensus is that they are utterly useless and serve no real practical purpose at all. My own personal suspicion is that somewhere in the world a product designer is howling with laughter for they included the mystical plastic finder into a multi-bit set just for fun to see what the reaction would be and since then they have been copied religiously and distributed by the millions, yet nobody can figure out any useful purpose.

Mice! Posted November 28, 2017 Report Share Posted November 28, 2017 they look like for holding hence the raised up parts for grip, does the chamfer tool fit in them? Or anything else in the set? Quote Link to comment Share on other sites More sharing options...

Or anything else in the set? They are supposed to be for holding screws in to help keep the screw driver centered on the screw, especially slotted screws, but as Gordon points out for the multi-bit sets they are the wrong size.

Someone had a job lot of wee plastic tubes and some springs and thought, let's mess with people's heads in the west. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted November 28, 2017 Author Report Share Posted November 28, 2017 Holding screws seems to be most logical explanation and it has raised parts for grip. The only snag being that bits don't fit through. Quote Link to comment Share on other sites More sharing options...
Fisheruk Posted November 29, 2017 Report Share Posted November 29, 2017 Could they be a depth gauge for slipping over a drill bit? Quote Link to comment Share on other sites More sharing options...

activeviii Posted December 13, 2017 Report Share Posted December 13, 2017 Its what thy call a slotted screw finder. taken from another site 1.Set the part that will hold the bit that will tighten the screw into the screwdriver. 2.Insert the screw finder into the screwdriver leaving the thinner part facing the mandrel. 3.Place the screw at the point that will be fixed with the head inside the screw finder. 4. Press the screwdriver until the tip of the bit touches the screw head. 5.Turn the screwdriver until the screw tightens enough to continue the work with more firmness and safety Quote Link to comment Share on other sites More sharing options...
