Machining micro-sized workpiece surfaces can be a challenge, but machine shops can now achieve superior surface-finish quality, accuracy and precision with the new Seco Tools JM100 Mini end mill series.

In micro-machining operations working on harder materials (up to 65 Rockwell) for tight-tolerance products, with zero or low visibility of workpiece and cutting tool, the JM100 Mini is up to the task.

As part of the wide and continuously expanding Jabro® range of solid-carbide end mills, the JM100 delivers longer tool life, stability and guaranteed surface quality thanks to its extremely precise geometries, virtually zero runout, advanced coatings and tight radius tolerances.

Tight radius tolerances of ±0.005μ on the tool reduce runout virtually to zero, increasing output and contributing to lower cost per part with high process precision, stability and reliability.

Targeted to achieve precise surface finishes on mould and die components, the JM100 Mini also helps shops minimize secondary benchwork that can increase production time.

The JM100 Mini is available in tool diameters from 0.2 mm to 3.0 mm, corner radii ranging from 0.05 mm to 0.3 mm RE = ±0.005 and overhang lengths from 1.5* DC to 20* DC, with two and three-flute versions.
