Standard Adjustable Hollow Mills

Standard Genesee Adjustable Inserted Blade Hollow Mills are detailed in this section - both positive rake and neutral rake. The smallest hollow mills produce diameters from 0" to 1/8" and the largest, diameters from 1-7/8" to 2".

GEN-DEX® Inserts

Genesee's large selection of precision ground GEN-DEX® inserts, either with or without positive raised island chipbreakers, provide the distinct advantage of the C tolerance on I.C. and thickness. This feature, normally available only by special order, contributes to optimum, balanced cutting of the hollow mill. Customers who choose to use our inserts will find they are able to hold +/-.001 or better on moderate to finishing cuts, with no additional adjustment of the hollow mill required after indexing.
