The Infinity Tools Precision Twist slot-cutting router bits are a new spin on a traditional slot cutter. What makes these bits so different is that they’re infinitely adjustable from 1/8″ to 1/4″ (Item 61-512) or from 1/4″ to 1/2″ (Item 61-513) with the twist of the adjusting nut on the top of the bit. With the ability to fine-tune your cut in .001” increments, you’ll always have the perfect size slot cutter for the job and never have to mess with those pesky, easy-to-loose shims on traditional, stacked slot-cutting router bits.

Each of these router bits includes a bearing that limits the depth of cut to 1/2". With a 1/2" shank and an overall diameter of 2" we recommend a maximum speed of 16,000 rpm using a variable-speed router or router speed controller. While these bits can be used in a hand-held router they're ideally suited for use in a router table or CNC machine. Each of these bits feature four carbide cutting tips of the same high quality and long life you would expect from Infinity Cutting Tools.
