Clarke pillar drill

[vmaximus]

I have an old Clarke 5 speed piller drill probably 35 years old but the drill bits slip in the chuck no matter how hard I tighten it up. So, what type of chuck would I need to replace it. The chuck has been taken off and it fits on a taper shaft.

depends on the taper of the shaft, they will vary from machine to machine, if the chuck goes onto a taper, it'll be a jacobs taper, but if the taper is on the chuck and fits into a hole them it'll be a morse taper.

this arbour shows what I mean, the chuck end is on the left and the drilling machine end is on the right

You mean right, right ?

I picked up a new chuck and arbor for my pillar drill a couple of years ago from RDG tools. Decent quality and cheap as chips. If you don't have it, the parts catalog for your drill will most likely still be available from Clarke. Google is your friend!

To clarify, the chuck has no arbor but fits onto a male taper from the drill quill, is that correct?

If so you'll need to determine what that taper is. It's probably, although not necessarily, a Jacobs Taper (JT).

This table should help you work out the correct taper if you have a vernier calliper.

Im quite happy with my chinese keyless chuck for the lathe, which came with a B16-MT2 arbour. Check if you need Jacobs/JT0-3 or a B taper.

Something like this.. ebay will be cheaper and have larger 16mm capacity ones.

While keyless are great they are about 50% longer if that may be a issue.

Take some pictures. One of the the chuck and one of the spindle. Is there any writing on the chuck?

Hello Vmaximus,

I have a Clarke drill which is probably about the same age as yours. The chuck is a number two morse fitting.

Thank you all for replying, having looked at the chuck I cannot see any obvious wear that would seem to make it slip on drill bits so I am going to give it a good clean out first and if it still happens then a replacement.
