About this series

SS Tuffy Grade Miniature End Mills

Every .001″ is standard — and we'll hand-select any size in between.

RobbJack SS stub-length Tuffy Grade miniature end mills are stocked in EVERY .001" diameter from .005" to .062" as standard. Need a size in between? Under .062" we hand-select tools to any diameter to the nearest .0002" — a .0376" tool is a regular order, not a special. Ball-end (SS-2BN) and 4-flute (SS-4) variants are also offered. Customers report these tools run faster and longer than any others they have tried.

  • Every .001" diameter from .005" to .062" is standard, shipped from stock
  • Hand-selected to ANY diameter in .0002" steps under .062" (e.g. .0376")
  • 2 flute, square end, 30° helix, stub length for rigidity
  • Ball-end (SS-2BN) and 4-flute (SS-4) variants
  • Tight tolerances held in microns

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.
