New VariMill II ER Extends the WIDIA VariMill Product Range

Born from the success of the VariMill I™ and VariMill II™ end mills, the VariMill II ER™ end mill offers the superior performance of its predecessors but with features that enhance stability. Due to its success as a popular and effective custom solution, WIDIA™ is now making the VariMill II ER end mill available as an option in the standard product portfolio. Bringing this option into the standard portfolio provides customers with fast, easy, and accessible ordering options worldwide.

Like the VariMill II, VariMill II ER end mills are engineered with five unequally spaced flutes. However, unlike with the existing VariMill product line, the eccentric relief (ER) available with this new tool’s cutting edges provides greater edge strength and enables high feeds and metal removal rates. The VariMill II ER end mill has a different taper core than VariMill I and II for increased stability, and also differs from those products because it’s designed for center cutting.

VariMill II ER is the first off-the-shelf tool to offer SAFE-LOCK™ by Haimer, which provides excellent stability, eliminates pull out, and makes the tool more concentric, overall. SAFE-LOCK is available on tools >1/2" (12mm) in diameter.

More than 100 VariMill II ER standard line items will be available globally in diameters from 3/8–1" (10–25mm). Though primarily designed for roughing and finishing applications in the aerospace industry, VariMill II ER tools can be used as a solution for any titanium or stainless steel machining and are capable of slotting, ramping, and plunging.
