Designation key: cutting diameter x length of cut x overall length - shank diameter - number of flutes. Ball nose codes carry the radius first. All shanks are plain h6 metric and run in standard ER11 to ER40 collets on BT30/40/50, CAT40/50, HSK-A63/A100 spindles. AluForce AL1 is also offered on a Ø3.175 mm shank for router spindles. Non-standard lengths of cut, necked reach and alternative coatings are ground to order - ask us with the feature you need to reach.
