I have made a tool handle for some carbide insert tools I bought online.
Here are the tools:
They sell a handle for them, which I bought:
However I was not impressed with it, its made from an aluminium tube and uses 2 grub screws to hold the shaft of the tool. It is so light that I find it a has a bad vibration problem, so I looked round for alternative possibilities. I found what is sold as collet extension that uses ER20 collets.
I got a 12 mm collet for it:
And a length of steel tube with a 20mm ID:
I drilled and tapped 2 holes for grub screws to hole the collet holder in place:
I tried this out and it was a major improvement over the bought handle, so to make it more comfortable to use I bought a length of foam sold for the handles on gym equipment:
I then turned a wooden knob to fit in the other end of the tube:
I drilled a hole for a screw to hold it in place:
Then I slid the foam over the pipe and fitted a screw:
Here is the finished tool, it works well and is quite nice in the hand as well:
