2-1/2" Half Round

2-1/2" Half Round

This 2-1/2" half-round measures 2.500" wide by 1.250" thickness, allowing the detail to be milled from six-quarter lumber. The common profile is comprised of a 1-1/4" radius half-round arc. Be aware that this knife design is not intended to be used as a bullnose cutter; it has no blend area built into the design. The detail is milled from the top cutter head and runs .020" away from the bed plates on the machinery. If you're looking for a bullnose cutter, please review and consider bullnose 2.500".

Before you begin knife grinding procedures, please read our article on knife cutting circles to see if you can safely mill this pattern on your machinery, this profile will not be able to be milled on certain models of molders.

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. For knife quoting purposes click to open the calculator below; we have added only the important measurements; enter the appropriate dimension in the boxes provided. A brief detailed explanation of how to use the calculator is located here. Need some assistance with the dimensions? Print a copy of our fraction-decimal-millimeter chart and place it on the molder to help operators save time and increase accuracy during machine setup.

Width = 2.500" / Depth of Cut = 1.250" (top knives)
