Metric
Metric HSS end mills are sized in true millimeter increments rather than fractional-inch equivalents, making them the correct choice for metric-spec drawings, imported equipment, and international customers. Available in 2 flute square end and ball end profiles.
Why True Metric Sizing Matters: A metric-dimensioned print calls for a metric tool — using a fractional-inch end mill as an approximate substitute can introduce tolerance errors that compound across a job. True metric sizing avoids this.
Square End vs. Ball End: Square end tools handle general-purpose slotting and pocketing, while ball end tools are used for contoured and 3D surface work.
