Whiteside Slotting Cutters and Arbors

Whiteside carbide tipped slotting cut precise, repeatable slots, rabbets and dados. Depth of cut is controlled by the the guide bearing, so unlike a table saw, a slotting cutter and router have no trouble following curves or complex shapes.

Whiteside slotting cutters are 1 7/8" diameter, with 5/16" bore. Arbors come standard with a B5 bearing for a 1/2" depth of cut. To change the depth of cut, switch out the bearing. For reference:

Use B20 Bearing for 9/16" depth of cut.

Use B25 Bearing for 3/8" depth of cut.

Use B26 Bearing for 1/4" depth of cut.

Use B27 Bearing for 5/8" depth of cut.



Cutters and Arbors are sold separately.

Simply put, joinery bits help you attach one piece of lumber to another with repeatable precision.

Slotting cutters consist of a cutter, and arbor available with or without provisions for a bearing. They can be used to cut rabbets, a tongue and groove, or the slot for a biscuit.

Dovetail Cutters are spec’d by angle and diameter as measured at the widest part of the bit. You can use these cutters in a standard router or with your dovetailing system. Bits are available for Incra, OmniJig, and Leigh among others. Check the Product spec table for compatibility.

Glue Joint router bits, and sets cut joinery that is ready to glue into place. Variations include tongue and groove, lock miters, and multiside bits to name a few. For ease of assembly these bits take the cake.

Multiside bits are used to create 6 or 12 sided polygons with a simple birds mouth joint.

Tongue and Groove bits add simple sturdy construction to nearly any project. Some styles of bit cut both sides of the joint, others as a pair of matched bits.

Rabbeting bits are typically used for creating a shoulder along the length of a board. In terms of strength, a rabbeted joint beats a butt joint, bacon to biscuits, and speaking of biscuits...

Biscuit bits are designed to cut the slot for lenticuliar floating tenons, or biscuts. Because of the small size of the tenon, and the simple set up of the router, biscuits are great for projects that simply need a bit of extra strength, or a cup of get-up-and-go.

Mortises are typically cut with an up cutting spiral fluted straight bit Also of interest to the mortise minded is the Whiteside Corner chisel, used for squaring the sides of a routered mortise

Fine Wood Working had this to say about Whiteside in their May June 2007 Router-bit review: "At the end of the day, the Whiteside and the Eagle bits had risen to the top of the mix, tying for the highest score. Lee Valley had the second-highest score, followed by Southeast and Woodtek in a tie for third. By the way, Whiteside also had the best bit when we reviewed straight bits in our August 1999 issue (FWW #137). We named the Eagle and Whiteside bits best overall. And, since the Whiteside had one of the lowest prices of the top bits, we also named it best value."
