Don't suppose you've got a link to the 1mm slot drill you use please ? Do they snap often ? I've always wanted to go smaller, just didn't want to chuck money away by buying garbage.Trevorturn":1oqgcji4 said:I use a 1mm 2 flute carbide slot drill
I run that at around 10000 rpm in my Kress spindle
I typically use a feed speed of 150mm /min
I have found that you don't get chipping if you use 0.9 step down (2passes on 1.5mm thick mop)
I either glue or use a good quality double. Sided tape to hold the mop on of piece of MDF
The MDF is sacrificial as you must cut over depth to avoid creating chiping if you have to break the pieces out of the blank
Always place the mop good side up
