RobbJack PM single flute up-shear router with polished flute for plastics

Best tool for plastics — polished single flute that eliminates material sticking to the tool and melting in the cut.

  • 1 flute polished-flute design gives the chip the whole gullet, so soft plastics evacuate before they can re-weld or melt in the cut
  • PM = up-shear (pulls chips up and out, best general chip clearance); PMD = down-shear (pushes down on the material for clean top surfaces and thin sheet hold-down); GTS = 2 flute straight (0° helix) for materials that must not lift at all
  • Tuffy grade carbide substrate
  • PM sizes 1/8"-1/2" including long versions (PM-108-06L, PM-108-08L); PMD in 1/8", 3/16", 1/4"; GTS in 1/8"-1/2"
  • Metric MPM up-shear from 4mm to 12mm
  • Also the best tool for gummy/soft aluminum — polished flute reduces material sticking to the tool
  • Tolerances: cutting dia +0.000/-0.002, shank dia -0.0001/-0.0002, flute length +0.060/-0.000, OAL +/-0.060
  • Materials: plastics, wood, aluminum; dry, wet, cold air, or spray mist

About this series

PM / MPM / PMD / GTS Tuffy Grade Carbide Routers

The best tool for plastics.

RobbJack's Tuffy-grade carbide router bits include the PM (1-flute up-shear, polished), MPM (metric 1-flute up-shear), PMD (1-flute down-shear, polished), and GTS (2-flute straight flute) series. These uncoated, polished tools are the best tool for plastics, eliminating material sticking to the tool and melting in the cut.

  • 1-flute up-shear (PM), 1-flute down-shear (PMD), and 2-flute straight (GTS) configurations
  • Polished flutes
  • Metric 1-flute up-shear (MPM) available
  • Eliminates material sticking to the tool and melting in the cut

Aluminum, Plastics, Wood. Dry, Wet, Cold Air, or Spray Mist. Applications: slotting, side milling, helical interpolation, ramping, roughing, semi-finishing, finishing.

Best for

  • Routing plastics without melting or material buildup
  • Aluminum and wood routing

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.

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.
