Lapping Fluid

[Garno]

I am in the market for some lapping fluid so I can sharpen my carbide inserts on my chisels.

I started browsing for some on the old interweb thingy and have once again managed to confuse myself :iknow:

Are all lapping fluids the same? and should I just get the dirt cheap one and make do?

I use the trend lapping fluid for my diamond card, not too expensive and lasts a long time

I read somewhere that plain water with a drop or two of dishwashing detergent works just as well as commercial lapping fluid.

I also read that 'personal lubricants' can be used for lapping - - -

+1 for the Trend fluid, on the Scarey sharp I just use plain water with a tiny big of Fairy liquid, and then dry my chisels and oil afterwards

I just spit on a diamond card works perfect but then I’m tight ol git lol

I just buy new inserts as when mine a blunt or chipped a new one is needed as the diamond card will take forever, OOPS you meant on woodturning tools throw the tool away and use proper tools

Water and dishwashing fluid,perfect results. One marathon was during and after turning Mammoth Tooth my mate in the US used 20 new 4 way cutters I used one sharpened this way so I vote with my experiences.

I sharpen them dry on an inexpensive four sided diamond block from Lidl. If you want to use a lubricant many seem to use cheap window cleaning liquid from the supermarket.
