Standard-length miniatures for added reach — any size, hand-selected.

RobbJack SR standard-length Tuffy Grade miniature end mills offer longer flute lengths than the stub-length SS for reaching deeper features, in EVERY .001" diameter from .010" to .062" as standard. Like all RobbJack miniatures, sizes in between are available hand-selected to any diameter to the nearest .0002" under .062". Ball-end (SR-2BN) and 4-flute (SR-4) variants are also available.

  • Every .001" diameter from .010" to .062" is standard
  • Hand-selected to ANY diameter in .0002" steps under .062"
  • 2 flute, square end, 30° helix, standard length for reach
  • Ball-end (SR-2BN) and 4-flute (SR-4) variants
  • Cutting dia. tolerance ±.0005"

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.
