Review on 🔧 SPEED TIGER Carbide Square Mill - Precision Tool for Enhanced SEO by Joshua Garris

who have been waiting for these tools and all three I have purchased were 0.312" which is why I have them can't use this. The normal tolerance for a 5/16" end mill or ball end mill is 0.000" / -0.002". They are all +0.004". Defect (oversized) on the finishing tool If they were precision machined I would definitely buy more I was very happy to buy from Taiwan as they are an American ally and not China. I know Taiwan can make excellent products, but the quality control of this item needs attention. When you buy them, please measure them carefully before assigning the tool diameter in your CNC.
