Deep Reach Router Bit Solves "Deep" Issues

Routing a deep recess in a walnut tray with the Infinity Deep Reach bowl and tray router bit

Our standard bowl and tray bit is great for routing out a shallow tray up to 7/8” deep, but if you want a deeper tray your “go-to” option has been a collet extension.

Collet extensions help, but are wider than the bearing on the bit, so you still can’t get to a truly deeper depth.

Infinity is proud to introduce our new Deep Reach bowl and tray making bit. It helps you overcome the shouldering issue on deeper cuts, where the collet extension has a larger diameter than your router bit. That size difference limits your possible depth of cut. With our Deep Reach bit, you can now mill deeper than ever before without the need for a collet extension!

This bit is 3-51/64 in overall length, and is meant as a secondary bit, used after you’ve defined your shape with the standard-length bit. Start by milling your tray as usual, using our standard 51-501B bit.
