Straight Top Groover — 1-3/4″ Width, Pro-Line (1-1/4″ Bore)

Cuts a flat-bottomed 1-3/4″ groove for wide housings, timber joints and deep rabbets — the second-widest in the range — and does two more jobs besides: run it against the fence to cut a rabbet, or fit a 4″ diameter rub bearing and it becomes a flush trim cutter following a template or a previously worked edge. The straight top grind leaves a square groove with clean corners — nothing is rounded, coved or ogee’d. Freeborn indexes the series by groove width and the trailing SKU number is that width in sixteenths, so 028 is 1-3/4″ and 032 is 2″. At this width, take the cut in stages rather than full depth in one pass, and keep the feed steady — the wider the cutter, the more the spindle feels the load. Pro-Line body: 1-1/4″ bore, 4″ diameter, three wings, counterclockwise, in carbide or T-Alloy. The Mini-Pro counterpart is MC-62-028.
