1mm Drills & chucks

[Munroast]

Always seem to be too small for chucks, have tried wrapping wire and stuff around drill with varying degrees of success (seldom centred properly then easily snapped)

Anyone tried something like this ?

or any other thoughts ?

My little Dremel has the collet chuck principle, as well as a small conventional chuck......works well enough but for a 1mm drill, a collet is preferable.

now there's a thought, I have access to a dremmel I wonder if one of the collets would fit a 1mm drill - I'm sure it don't have any traditional type chuck

Or a pin chuck (sometimes called jeweller's chucks) - specifically designed to hold smaller tools and cutters. Larger chucks have flats on the jaws which limit them to about 1.5 or 2mm or so minimum diameter. Pin chucks overcome this. Trend have a 1/4in hex bit adaptor which holds a 1mm drill bit in a spiral spring collet (Snappy range)

BTW, does your drill run sufficiently concentric to accommodate such a small drill without breakage? A lot of cordlesses aren't that good

I use one of these.

That's a pin chuck....

Indeed, and I also noted your comments around on not running concentric, I will examine that when next in the workshop. it certainly wasn't running that concentrically with some wire wrapped around the drill to get the chuck to grip - but I did get the job done without snapping the drill.

I also ordered that collet set from the OP. for £3 I can't go far wrong - its from china so could be a while (or may be beat the chuck ordered from the UK)

Why are cordless drills so poor at not running concentric ? I have access to about 4, all good makes and good tools, but put a small drill in and it is clear they wobble too much.

Got both the pin chuck and the collets now, both are excellent for holding small drills, the collets are probably better as they hold the drill closer to the main chuck, but it still wobbles a bit.

its worth noting a 3/8ths[8mm] chuck will tend to go down to 1.5mm and 1/2" [13mm] will do 2mm

pilot holes in wood or softish plastics panel pins ----a bit off a faff sometimes getting it concentric but cheap wont break and come in large multi packs

Cheap chucks, cheap drills. I have a Makita DHP481 which comes as standard with a very high quality all-metal Japanese chuck and that runs true. Those chucks are more than £100 bought as a spare part. The couple of cheaper Makita drills I've got are awful in comparison. At one time if you bought a pillar drill you could pretty much guarantee chuck run-out measured on thous - these days there's a lot of cheap Far Eastern junk around where you can almost measure the run-out with a tape measure. For big drills on woodworking or home projects this often isn't an issue - not true when you start using tiny drill bits, though,

pilot holes in wood or softish plastics panel pins

Back in the days of "egg whisk" drills, and for those of you who don't know what I'm wittering on about, I am referring to the original environmentally-friendly cordless drill:

pilot holes for woodworking were often produced by taking a panel pin or the like, snipping off the end with your nipper, chucking the beheaded pin in the drill, then drilling a hole. Works with small nails, too. Surprisingly effective and if you are piloting for something like gimp pins, panel pins, small nails or the like it produces a hole that matches the fastening you are using (obviously). There were also jewelers' versions of these drills with chucks that could hold drills down to a fraction of a millimetre diameter
