Frequently Asked Questions

A single-flute / spiral style cutter with a rounded “O” flute profile designed for smooth chip evacuation and reduced heat buildup.

Excellent for plastics (especially cast acrylic), non-ferrous metals like aluminum, phenolic, and some composites — they’re optimized to reduce melting and smearing.

Yes — many users run O-flute bits in aluminum successfully, but you must tune feeds/speeds and use proper clamps/coolant as needed.

O-flute gives smoother pockets and better surface finish in plastics because of its flute geometry and chip-clearing behavior.

They help a lot—paired with correct feeds, cast acrylic (not extruded) and good chip removal, O-flute minimizes melting and edge chipping.

Single (including O-flute) clears chips more aggressively and is generally preferred for plastics/aluminum; two-flute can give a finer finish but may clog more easily.

For aluminum, coolant or mist helps; for plastics, compressed air or excellent dust/extraction, and the right feeds usually suffice.

For aluminum, coatings (TAC, TiAlN, ZrN, etc.) and solid carbide constructions help with heat resistance and life.

Yes—commonly used for pocketing and profiling; slotting is possible but requires appropriate depth, multiple passes and caution.

Measure at the widest cutting edge; note that tool deflection and CAM tool offsets affect effective cut—always verify with a test cut.
