[ ! ]For shank diameter (d) specifications listed in orange, specify a tip (R), under neck length (ℓ1) and shank diameter (d).

More Information

● The XAL coating with excellent lubricity is ideal for general steel, copper and aluminum machining.
● The long neck helps to avoid tool interference when machining in deep areas.
● Delivers a finish with very good surface roughness after machining.
[ ! ]The XAL coating does not have conductive properties. Cannot be used with conduction type tool setters.
