Posted 13 January What you're looking for is hard to find and pricey when you do. Unless you're after a "correct" tool and just want something to effectively do the job...a 1.25" end mill will work better than you might imagine. Ebay Link I bought the same end mill off Ebay and it cuts and cleans the carbon out of BMG boosters like nobody's business. Hope that helps, Jon Share this post Link to post Share on other sites
