The smoothest dovetail cuts you've ever made. Dovetail joints are notoriously demanding—you can't take multiple shallow passes, and the widest part of the cut is at the tip of the bit, inviting chatter and tear-out. That's why Ultra-Shear Solid Carbide Spiral Dovetail Bits are engineered to perform where others struggle. By merging spiral geometry, micro-grain carbide, and ultra-fine grinding, these bits deliver cuts that are sharper, smoother, and cleaner than traditional dovetail bits.
Spiral cutting action: Like a spiral straight bit, some part of the edge is always in contact with the wood—eliminating the “choppy” interrupted cut of standard dovetail bits.
Fluff, not dust: Watch the difference as chips come off light and fluffy, a sign of clean slicing rather than scraping.
Solid carbide construction: Long-lasting sharpness with precision-ground geometry for flawless joints.
Whether you're working on a horizontal routing system or a router table, these bits give you the most precise, chatter-free dovetails you've ever cut. They don't just look different—they are different. Available in 8°, 10°, and 14° dovetail angles (all 1/2" shank, 1/2" wide at the dovetail base): 8° – 13/16" cut length
10° – 25/32" cut length
14° – 9/16" cut length
