Shop Our Complete Line of Router Bits

These router bits have several unique features.

The double-flute upcut spiral design ensures rapid, clean waste removal, particularly in plunge routing where the specially designed end mill lets you plunge without fear of plugging and heat generation.

They are excellent for grooving, slitting, blind routing and end milling.

The bits range from 2" to 3 1/2". Solid carbide, they are suitable for all woods and non-abrasive plastics. The 3/8" and 5/16" shank diameter sizes require separate bushing adapters (sold separately).

The 1/4" and 3/8” bits are suitable for use with our router letter template set.

Made in USA.
