Is there a trick to limiting the clogging of carbide burrs when die grinding aluminium?
Thanks,
Julian

A lubricant applied directly to the burr will immediately shift any loading of stock and will prevent build up, dry PTFE lubricants such as chain lubricant work really well, or even WD40 sparingly applied. Regular applications will prevent build up and prolong the life of the burr, make sure you do most stock removal with ally cut burrs which have wide flutes, you can use double cut for finishing. Once the burr warms up it will tend to load up more rapidly. TiN coated burrs will load up less readily. Faster speeds will encourage loading up.
