I have noticed that it is getting harder to find drill bits for pen kits. Why do our suppliers not ask the manufactures if they can make the kits so as the tubes are metric which seem to be the easiest bits to get or are the suppliers on a good screw selling the imperial bits.
I am now going to get my coat and leave the building for a while
I believe we are on the end of consideration for pen kit sizes they the makers seem to sub out brasses etc to specialist people ending up packaging and selling least ways Timberbits on his travels to them has described them this way cottage industry nearly.
In the electrical business my experience was nothing from one mob ever fitted the others products so call bastard threads were the norm. Remember Land Rovers full of exhaustive numbers of nuts and bolts costing big money to have work done on them for many years the petrol tank was under the drivers seat, GMH with their early Holdens full of fat self tapping screws. In Civil Aviation I spent years out on freezing runways planes circling repairing landing lights freznel furnished almost impossible to pull down and fix, The primitive strouger relays controlling taxiway etc lighting that had piggy backed contacts that had to be stroked with a special tool to set them up. Mixed American manufacture of stray voltage converters ganged up in crazy fashion in critical installations.
Bottom line is they price down, bulk handle ,where price rather than quality reigns. Beware of the sleeping giant. I am not deceived enough to think that makers are ready yet to standardise with common threads or standard brasses.
Coming back to drills they are notorious for their minor variations from their stated sizes anyway.
WE are in the swings of the roundabouts with Imperial and Metric with so many in between.
I like Engineering sales where real choice still can be found and quality is the norm.
Have success mate we all try our best.
