So, as I’ve mentioned elsewhere, I bought a couple of these, contacted the supplier to ask about speeds and feeds, and had a bit of a shock.
They’ve told me the following (which doesn’t relate in any way to the information provided for similar sized bits from the Carbide3D range and settings):
Tool diameter: 0.25"
Depth of Cut: 0.125"
Speed @ 18,000rpm
Hardwood: Feed rate @ 4000ipm, plunge rate @ 2000ipm,
Softwood: Feed rate @ 5000ipm, plunge rate @ 2500ipm
Plywood: Feed rate @ 6000ipm, plunge rate @ 3000ipm
Do the feed rates, and especially the plunge rates, seem a bit high?
