This 1-5/8" half-round measures 1.625" wide by .750" thickness. The convex profile comprises a 1-5/8" wide half-round circle, a great profile to utilize fall-off rips of lumber. The knife design is not intended to be used as a bullnose cutter because it has no blend area in the cutters. The detail is milled from the top cutter head, and the knives will come very close to the machine bed plates. Please search our bullnose profiles for a nosing that is milled from either the right or left vertical cutter heads, these patterns have blend areas built into the knives.

Ever wonder why certain species of lumber have tear-out problems during the milling process? Find out more on how to reduce and eliminate tear issues by changing the cutter head hook angle on the knives. Purchasing 12/20 duel angle cutter heads will save a substantial amount of money when investing in this style of tooling.

Caution; the cutters will come within .020" of the machine bed plates when milling this detail. We recommend a wooden, phenolic or plastic sacrificial bed plate be used for these milling operations.
