I bought a second hand pillar drill, which appeared fine at the time. It is a Sealey SDM90.
It has a 3 spoke handle which attaches to the splined drive pinion/shaft. However the handle rotates around the drive pinion when the drill bit contacts the work. Appears to be ok under no load.
Have been on to Sealeys tech dept. It is missing a small pin which they can no longer get hold of.
Here is a link to a photo which shows the problem.
It is not a morse taper. Hole goes through the end of the spline. There is no corresponding hole in the hub of the handle.
