3-in-1 Flush Trim Bit
CMT 807.128.11 is the exact 1/2-inch-diameter variant in the 7/8/907 3-in-1 flush-trim family for MDF and laminates. It combines a 1/2-inch cutting length, 2-9/64-inch overall length, 1/4-inch shank, two HW carbide cutting edges, right-hand rotation, shear-angle conical edges, and a Delrin® triangular guide bearing.
Main Product Description
CMT 807.128.11 is one exact Item Code within the official 7/8/907 3-in-1 flush-trim-router-bit family for MDF and laminates. The verified USA and Canada row specifies a 1/2-inch cutting diameter, 1/2-inch cutting length, 2-9/64-inch overall length, 1/4-inch shank, two cutting edges, HW active cutting material, and right-hand rotation.
CMT's 3-in-1 system addresses three common laminate-trimming issues. The anti-stick Delrin® bearing reduces glue-related bearing seizure, its extended guide surface tracks the work without the scratching associated with a steel bearing, and the shear-angle cutting edge reduces the need for filing.
The conical cutting-edge design is intended to preserve clean trimming performance through repeated resharpening. The exact row identifies shield 990.422.00, screw 990.058.00, hex key 991.057.00, and Delrin® triangular bearing 791.042.00. Correct collet fit, bearing condition, projection, workholding, guarding, and machine limits remain essential.

Product Highlights
Verified 1/2-Inch Variant
Exact Item Code 807.128.11 combines a 1/2-inch diameter, 1/2-inch cutting length, and 1/4-inch shank.
3-in-1 Delrin® Guide Design
The anti-stick triangular bearing uses an extended guide surface for stable tracking with reduced glue adhesion and scratching.
Shear-Angle Conical Edges
Two HW carbide cutting edges combine shear-angle geometry with CMT's conical design to reduce filing and support resharpening.
Compatibility & Installation Notes
Confirm exact Item Code 807.128.11 and a clean compatible 1/4-inch collet. Inspect Delrin® guide bearing 791.042.00, shield 990.422.00, screw 990.058.00, and hex key 991.057.00, then verify cutter clearance, shank engagement, guarding, workholding, and the applicable machine limits. Do not substitute a standard steel guide bearing or select by the 7/8/907 family heading alone.
