New tools for Lotta

[rambo]

Finally got my package from UK.

• 10mm alu flat endmill to replace the one I destroyed, this one has 4 flutes instead of 3.
• 12mm 90degree chamfer mill / spotting drill
• M12x1.5 tap, this is my personal property but I guess it’s staying at the lab tool pool for now. Goes very nice with these cable glands

DO NOT USE SPOTTING DRILL OR CHAMFER MILL FOR ENGRAVING, we have already two chamfer mills with destroyed tips… they will work fine for chamfering still though.

Also: when spot-drilling make sure to have low feeds, the cutting speed at the center of the tip approaches zero, probably another reason for destroyed tips on the old chamfer mills (which were not really meant for spot drilling to begin with)

Also ordered a set of parallels (“särmäraudat”) identical to the one we already have, so it’ll be easier to attach large workpieces when they can be properly supported by two parallels on both ends.
