RobbJack XF Series 6-flute 45-degree helix Tuffy grade carbide end mill with AlTiN coating

6 and 8 flute, 45° helix Tuffy grade finishers for titanium, steels, and high-temp alloys — cut titanium up to 75 inches per minute.

  • 6 flute (XF-602, 3/8"–3/4") and 8 flute (XF-802, 3/4"–1") Tuffy grade carbide with 45° helix, AlTiN coated
  • Metric MXF line: MXF-602 in 10–16 mm and MXF-802 in 20–25 mm
  • Corner radius on every tool — .030", .060", .090", .120" by size (metric 2.0, 2.5, 3.0 mm); no sharp-corner version
  • Headline claim from the guide: cut titanium up to 75 inches/minute (1905 mm/minute)
  • Materials: titanium, cast iron, steel, stainless steel, and super alloys up to 40 HRc hardness
  • A dedicated side-milling finisher — applications are side milling, high-performance semi-finishing, and finishing (no slotting rating), run dry, wet, cold air, or spray mist
  • XF finish profiling guidance: about .1 × diameter radial width at 1 × diameter axial depth; see the guide's trochoidal tool paths at robbjack.com/robbjack-tv
  • Optional flats (-FL) on every inch size for high-torque holding; metric tools do not have flats
  • Anti-pull-out h4 shank tolerance — tightest in the industry
  • Tolerances: cutting dia −.001/−.002, shank −.0001/−.0002, flute length +.060/−.000 (MXF: cutting dia −.025/−.050 mm)

From the RobbJack Applications Guide.

Light radial, deep axial
Light radial, deep axial — Guide engagement diagrams: slotting at 1 × diameter width and .7 × diameter depth, XG-502 profiling at .5 × diameter radial by 1.5 × diameter axial, and XF finish profiling at just .1 × diameter radial engagement over a full diameter of depth — the multi-flute finishing recipe.

About this series

XF / MXF Tuffy Grade Carbide End Mills

The highest performing tool in steel, stainless & other difficult alloys

The XF Series is a high-flute-count (6 and 8 flute) Tuffy Grade carbide end mill with a 45 degree helix for finishing in steel, stainless and difficult alloys. AlTiN coated, offered as XF-602 (6 flute) and XF-802 (8 flute) and metric MXF equivalents. Anti-pullout shank technology delivers h4 shank tolerance, the tightest in the industry, to eliminate tool pull-out. RobbJack reports up to 15X the life of comparable tools, the ability to cut titanium up to 75 inches/minute (1905 mm/minute), and 304 SS slotting & profiling at 400 sfm / 24 ipm.

  • 6 flute (XF-602) and 8 flute (XF-802) configurations
  • 45 degree helix, square end with corner radius
  • AlTiN coated
  • Anti-pullout shank technology, h4 shank tolerance (tightest in the industry)
  • Available with flats (add -FL); metric MXF tools do not have flats
  • Supports trochoidal tool paths
  • Inch (XF) and metric (MXF) sizes

Titanium, cast iron, steel, stainless steel and super alloys up to 40 HRc hardness. Applications: side milling, high-performance semi-finishing and finishing (dry, wet, cold air or spray mist).

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.
