Expanding the Jabro range of solid carbide end mills, Seco’s JM100 Mini is designed for shops struggling to machine micro-size workpieces with adequate surface finish, accuracy and precision. Intended for use in micromachining operations with zero visibility of workpiece and cutting tool, the JM100 Mini is said to provide better tool life, stability and surface quality because of precise tool geometries, almost zero runout, advanced coatings and tight radius tolerances.

Engineered to achieve precise surface finishes on mold and die components and able to machine tool steel as hard as 48 to 65 HRc, the JM100 Mini thus helps shops minimize secondary benchwork that can increase part processing time. The end mill’s coating reduces tool wear to help lower overall tool costs and eliminate the need for frequent tool changes. Tight radius tolerances of ±0.005 micron reduce runout virtually to zero, increasing output and contributing to lower cost per part with high process precision, stability and reliability.

The JM100 Mini is available in diameters ranging from 0.2 to 3.0 mm (0.008" to 0.118"), corner radii ranging from 0.05 to 0.3 mm (0.002" to 0.012"), and overhang lengths ranging from 1.5×D to 20×D, with two and three-flute versions.


  • Tips for Tapping Titanium Alloys

    Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.

  • Rolling Threads Has Advantages

    With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.

  • Machining Dry Is Worth A Try

    Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
