Our Core Box Bits are available in several angles to cut rounded grooves and slots of varying widths that can be both decorative and functional. Sometimes called round nose bits, they are commonly used for sign-making, and are also ideal for fluted columns, finger pulls, drain grooves on cutting boards, drip rails for window sills and more. Two flutes. 1/4" shanks.
Onsrud up-cut spiral router bits are perfect for cutting mortises. The up-cut design helps keep the mortise clear of chips and shavings while you cut. Available in high speed steel and solid carbide.
These collet extenders allow you to change router bits from above the table-even without a lift! Even if you have a lift, they still make bit changes easier because you won't have to remove the insert ring. They're also great for custom made router tables with very thick tops, as they provide the additional depth of cut needed for many routing tasks. Use them with our Router Table Spline Jig (59288, sold separately) to achieve full depth of cut when machining dovetail splines.
Mill tenons of any length! Simply remove the top portion of the cutter (including bearing and spindle) to produce the front of the long tenon profile for blind tenons, through tenons or bridle joints. These precise bits work for any door 5/8" to 1-1/4" thick. Unique cutter geometry virtually eliminates tearout. Adjustable shims enable a tight fit when using plywood and also allow use with thick panels from 7/32" to 1/4" thick. High-density carbide composition and Perma-Shield coating lengthen bit life and protect against heat and pitch build-up. 1/2" shanks.
