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
