Plans wanted for Carbide Tip inserts tool holders
Posted: Sun Nov 07, 2010 6:33 am
I have seen one or two projects of fabricating your own Carbide Tip Inserts Tool Holders. Some of them was just flat (positive rake bit), but some of them specify for the tip to be on an angle (negative rake tip) to determine the rake.
I would like to get hold of some of these plans to make some myself.
Here in South Africa the tool holders are so expensive that a hobbyist can not afford them.
I have even welded the tips off some concrete drill bits and brazed them on square rods and that also seems to work as a cheap alternative.
I am also looking for info on boring bars.
I have even seen a plan how someone made a cut-off blade from a piece of saw blade on which there was a TCT, but I lost it.
