First test of the brazed carbide tube mitre cutter. Smooth as a baby's bottom. Hand fed at 325 rpm, cut time 11 seconds, painted-on Blasocut 4000 Strong coolant mitreing Reynolds 631 air hardening steel. Will test cutter on Reynolds 921 stainless and 853 heat treated steel tomorrow and some titanium asap. As soon as some scrap pieces of Reynolds stainless 953 are to hand this cutter will have a go.
