Whiteside Slot Cutter Arbor

A slot cutter arbor is used to mount a slot cutter in a router. The shank side fits into the router and the slot cutter is held on the other end with a hex nut.Slot cutter arbors are normally used with a bearing to control the depth of cut. Whiteside arbors include a 7/8″ OD bearing, which results in a 1/2″ depth of cut on standard 1-7/8″ OD slot cutters.

About Whiteside

Whiteside Machine Company was founded in 1970 in Bill Whiteside’s basement where he supplied tooling to NC’s huge furniture making industry. Whiteside is still family-owned but has now grown to occupy a 40,000 square foot factory in Claremont, NC.

Whiteside offers a full range of router bits. Their rigid quality control and precision manufacturing techniques have repeatedly resulted in highest ratings in Fine Woodworking magazine tool reviews.
