CMT 811.080.11 Router Bit

The CMT 811.080.11 is a straight-profile router bit with a 5/16 in cut diameter and two flutes. It is built for woodworkers and CNC operators who need clean, straight cuts in solid wood, plywood or composite panels. The carbide-tipped cutting edges resist wear during extended production runs. This bit suits both handheld routers and table-mounted setups.

Installation and common issues

The 1/4 in shank fits standard collets without adapters, so setup is quick on most routers. Ensure the collet grips the shank fully and that the bit is seated to the correct depth before tightening. Vibration or burning usually means the bit is dull, the feed rate is too slow or the workpiece is not secured. Carbide tips can chip if the bit contacts metal fixtures or hidden fasteners.

Questions about this item

How can I confirm the 811.080.11 bit is cutting correctly after installing it in my router?

Run a test pass on scrap material; the carbide-tipped, two-flute design should leave a clean, straight-edged groove without burning or chatter.

What comes with the 811.080.11 router bit and what extra items might I need?

The box contains the single carbide-tipped straight bit with 1/4 in shank; you will need a compatible router collet and workpiece material separately.
