They do an under 50 quid version... still a bit too spicy for me to buyPricey on amazon at least- looks fun tho
Probably a reseller trying to catch someone out £45-55 elsewhere.Pricey on amazon at least- looks fun tho
V5 arrived today, filled in online on Monday PM, that was quick!Yet another knackered Series Land Rover ...
That's this weekend sorted then!
Funny you say that small keyless chucks on battery drills are crap.I've bought this set as a jobber set .
Not a lot of accuracy required.
So I can cope with the shank little worn out.
But I have a complete 4-13mm Dormer set with 0.25mm increments in sizes which just needs to be sharpened properly cause most people ruins the bits when they try to make them cut better .
Then I have a perfect gühring set 6-10mm 0.1 increments .
I am getting rid of all the key chucks
Because of the reason you explained up above, plus no matter what, you can even tighten it the correct way, they always have an excessive run out because of their construction .
Keyless chuck , I mean the real ones ,not the ones you'll find on a cordless drill , but the chucks you usually use on a mill or a lathe ...
They have 1 screw and not 3 (the jaws on the key chucks) and a fixed nut coaxial with the chuck ,instead of a moving one (the gear you tighten up using the key) which adds slack .
Another thing the jaws on a key chucks hardly have been ground, reducing accuracy,once more the run inside holes,again they need tolerances another accuracy lost .
On keyless chuck (I call them keyless for convenience) jaws are first of all precision ground and quite hard too .
Then they run pushed against a ground surface.
This ensures both parallelism of the contact surface to the drill bit shank , and concentricity.
Those things don't happen on a key chuck because of the mechanical tolerances mentioned up above, plus they come in contact at an angle so inevitably they can't never be parallel, never have the same contact surface to ensure holding strength, and in addition the jaws will inevitably rotate a bit reducing a lot the pressure applied on the shank.
Well there's more.
Keyless chuck if you push the bit to the bottom ,while tightening it will be forced to stay there , because the action of the jaws will push the bit against the bottom .
Key chucks do the opposite again loosing holding strength.
Another thing and then I promise you to stop being a teacher without knowing anything.
Cause I'm sure there's a whole lot of reasons why those things happen, I've tried to share what I've understood about the main differences between those two chuck variety.
Drill chucks are rathed for a specific shank size range.
Ideally you need different chucks for different drill's sizes.
For example
I'd use a 0 to 6 mm chuck for holding bits up to 4mm
0 to 10 or 1 to 10mm one for bits between 3 to 7 let's say 8mm
1.5 to 13 between 5 and 10mm
A 3 to 16mm between 8 and 14mm
There are bigger ones but at this point they are most likely reduced shanks or already available with morse taper shank and that would be my preference.
Bigger cylindrical shank than 14mm should be held on a collet chuck IMHO
Maybe the most annoying and lesson looking post I've ever written in here.
I'd like to remember that I'm not trying to teach something to anyone, I'm not able to explain something without looking Mr I know everything.
I hate that myself.
My apologies
Funny you say that small keyless chucks on battery drills are crap.
I received a TEMU battery drill special today , it won't hold a 4mm twist drill being poked into 20mm of chipboard for a pilot hole. I put one of the Chinese hex shank punched on to the drill shank , four holes and it too started to self loosen , I'm about to go searching the world for a keyed replacement 0,8mm to 10mm chuck ---- 3/8 ,24 UNF for it . If it's not possible it's going back or I'm asking for a refund .
I do have a 13 mm Kielder battery drill that has a great chuck grip even on tungsten & polished cobalt drills
They are very good, the handles are heavy, they act like a flywheel, give them a spin when installing clean fasteners.Seem decent quality. Lifetime warranty.

Get well soonI'm at the hospital since 2pm
Opened the results of a tac and ran to the hospital
A stone is stopping a kidney
So 4 to 5 hours here depressing my self
Good thoughts your way, and hope it gets better soon.I'm at the hospital since 2pm

Well due to having very painful trigger ring fingers on both hands I've opted to have a keyed chuck and will be adding 40 mm extending rod on the longest arm ........ cheap at £8 ish .Albrecht keyless chucks are a great quality piece of gear !![]()
Interesting but very expensive. I hate flies.Could not resist. Perfect complement to my new sun deck...

I blame YouTube but yes, it is in fact awesome!
