Mounts and kits the maker excludes

Spindle kits that name it
Onefinity Redline 80 mm kits: 1.5 kW (ER20, 110 V, air-cooled) and 2.2 kW (ER20, 220 V single-phase, air-cooled)[3][4]Onefinity's own kits; their pages do not state a per-generation machine list.
Supply the maker's kits require
Onefinity: the Redline VFD requires a 15 A breaker, and GFCI installation may cause frequent false tripping. The 2.2 kW kit is 220 V single-phase with a NEMA 6-15P plug; the 1.5 kW kit is 110 V.[4][3]Quoted from the maker. The kit manual and a qualified electrician decide the circuit; never remove or bypass GFCI protection.
Collets supplied
Redline 80 mm kits: ER20 nut with 1/2, 3/8, 1/4 and 1/8 in collets[3][4]These come with the spindle kits, not with the machine.

Dust boots that name it
Onefinity Suckit SM (Gen 2): 80 mm spindles only; port 67.60 mm (2.66 in) outside and 57.93 mm (2.28 in) inside diameter; 30 mm and 50 mm magnetic brush rings[5]Onefinity also calls it a 2.5 in port, which matches neither listed figure exactly; treat 2.5 in as a nominal label. The SM slides over the spindle and moves with the Z axis.
Maker support for third-party parts
Onefinity says it no longer offers parts or support for other machines.[6]
Revisions and conflicts
Onefinity distinguishes the spindle-mounted Suckit SM, which moves with the Z axis, from the original Suck It and Suck It Pro, which a maker reply says work with both 65 mm and 80 mm boots.[7]

  • The Gen 2 80 mm mount does not fit Original, X-35, X-50, Gen 1 Elite or wall-mounted machines.
  • The Suckit SM fits 80 mm spindles only; Onefinity says it will not work with 65 mm spindles or the Makita router.
  • The Suckit SM port is listed as 57.93 mm inside and 67.60 mm outside diameter, so check your hose against those figures, not the 2.5 in label.
