Minimaster Plus Line of End Mills


Minimaster Plus end mills boast  advanced features for tackling the most demanding of milling applications in steel, stainless steel, cast iron, aluminum and other difficult-to-machine materials.

The most notable new feature on the Minimaster Plus is the high-precision interface between the replaceable carbide insert and the steel shank. The insert has an internal thread and external taper, while the shank has an internal taper with a threaded center pin for added reliability and stability as well as minimized run-out.

Additionally, a new axial stop on the shank increases repeatability and productivity by allowing end users to replace an insert without having to remove the tool from machine spindles. The new insert then repositions axially within 25 microns.

Intended for general machining in the aerospace, power generation, die and mold, automotive and medical industries, the highly productive Minimaster Plus replaceable tip milling system makes tool-length re-measurement obsolete. The milling system offers a large selection of inserts and shanks for a multitude of tough milling applications.

Twenty-four versions of the shank are available, along with square shoulder and ball nose inserts that have through-tool coolant on all two and three flute designs for excellent cooling and efficient chip removal.

Inserts come in two grades for machining all types of materials and E- and M-geometries for a smooth cutting design. Insert diameters range from 0.375” to 0.625”, and corner radii are available from 0.0157” to 0.122” to match a variety of design requirements.
