Create “rattle-free” flat panel doors and mill tenons of any length with these
quarter round bits. Works 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. 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.
High-density carbide composition and Perma-Shield coating lengthen bit life
and protect against heat and pitch build-up. 1/2" shanks.
