Drill Tolerance

[Twister]

what is your thoughts on this?
so tight it squeezes all the glue out?
is 0.3mm too much ?

Has the drill been sharpened that can make them under sized

But if you buy a 10 mm drill it should have a 0.05 tolerance

maybe i rephrase...sorry
e.g. if i need a 10.5 and my closest bit is 10.8 is that ok
or do i go and get another bit


especially when imperial not easy to get in these sizes and above

Personally I'd always use the correct size drill which reminds me I need to order bits to make the Sedona s I got recently.

 

[Twister]

Sedonna is 25/64" (10mm) & 15/32" (12mm)

save u looking it up :-)

i just need a google for some imperial bits i want now
not the easiest items to search

You might want a reduced shank drill for 33/64 I bought one and I had to grind the down make sure your chucks are able to hold a 14.50 mm drill

Yep I have reduced shank. Most drill chucks only take up to 13mm

 

[Twister]

wish was that easy
no hole in my quill

It's basically a Morse taper.
If you bought your drill from new you should have been provided with a tool to eject the chuck.
A "Drift"
If you have a cheapie, you may have 2 drifts to tap in at opposing sides to release the chuck.
If all else fails cut a fork shaped wedge out of hardwood, and tap in between the quill and chuck.

Even without the hole, the principal is the same, you need to drive a wedge between the top of the chuck and the bottom of the quill, which will eject a Morse taper.
Two wedges are better than one so you do not exert to much sideways pressure on the quill.
