Odd thread on tool?

[Davek0974]

I bought some blue sanding discs recently, was'nt until I went to fit them to my grinder that I realised I bought the wrong size

Best solution I thought was to buy an air operated grinder to use them on - you can never have too many grinders right

Then realised it needed a matching backer pad - check the advert for the grinder - 10mm thread, pad ordered.

Went to fit pad and disc - thread no good, way too coarse so definitely not M10 or even M10 fine!

Got the thread gauges out and its a 3/8" x 24 UNF thread on the spindle, WTF??

Made a new clamp nut on the lathe in the end, and got it working. Just thought it a bit of an odd thread, it's a SilverLine tool too.

Thread was standard chuck spindle thread on Black and Decker drills.

Interesting, but it was a new item, I would have expected a metric one.

Silverline...says it all to be honest.

Next one out the factory probably had an M12 thread...

A tool is something of use that helps to do a job effectively/efficiently

then there is silverline, buy 10x more than you would think you would need and take 3x as long. Can you call that a tool?

Ah so it's bit like the Chinese thread-of-the-week choice

I always though they were a reasonable budget tool, seems not any more.

Lets see how long it lasts
