Standard-length miniature end mills — deeper reach in every .001-inch size from stock

  • Every .001-inch diameter from .005 to .062 is standard — all shipped from stock (SR-2 table runs .010–.062)
  • Hand-selected to any diameter to the nearest .0002-inch under .062
  • Standard flute lengths (3x diameter, e.g. SR-2-010 has a .0300-in flute) for deeper miniature slots and walls
  • 2 flute, 30-degree helix, square end; ball end (SR-2BN) and 4 flute (SR-4) versions available
  • Tuffy grade sub-micrograin carbide, rated for materials up to 40 HRc
  • Tight tolerances: cutting diameter +/-.0005-in, shank diameter -.0001/-.0002-in, flute length +.003/-.000-in
  • Uniform 1/8-in shank and 1-1/2-in overall length across the range (metric MSR: 3 mm shank, 38 mm OAL)
  • Coatings available: TiN (-T), TiCN (-C), AlTiN (-A) and DLC (-DLC)

About this series

MSR-2 Metric Tuffy Grade Miniature End Mills

Metric standard-length miniatures for added reach

The MSR-2 is the metric version of the SR-2 standard-length, 2-flute, square-end Tuffy Grade miniature end mill, with longer flute lengths than the MSS-2 stub for deeper features. Cutting diameters range from .25 mm to 1.50 mm on a 3 mm shank with 38 mm overall length. Ball-end (MSR-2BN) and 4-flute (MSR-4) standard-length variants are also offered.

  • 2 flute, square end
  • 30 degree helix
  • Standard length
  • 3 mm shank, 38 mm OAL
  • Tight tolerances
  • Cutting Dia. tolerance +/-.010 mm

Available uncoated and in TiN, TiCN, AlTiN, and Diamond-Like Carbon (DLC) coatings

RobbJack's tested starting numbers for this exact tool, from the same engine and the same default machine as the calculator: a 12,000 RPM / 400 IPM / 30 HP machining center, rigid setup, full-depth cut. A faster or smaller spindle changes the RPM and feed — enter yours in the calculator and it re-governs every number.

Read before you run

Recommendations are computed starting points based on typical conditions — not guarantees of performance, tool life, or fitness for your application. Machining involves inherent risk: you are solely responsible for safe operation, for verifying every parameter against your machine, spindle, toolholding, workholding, and guarding limits, and for proving all parameters on a test cut before production. RobbJack Corporation assumes no liability for tool breakage, machine damage, scrapped parts, production loss, or personal injury arising from use of these recommendations. By using this calculator you accept RobbJack's Terms & Conditions.
