Bullnose profiles are generally milled from either the right or left vertical cutter heads, they are not intended for milling half round profiles due to the extra blend area incorporated in the knife design, this extra knife extension would strike the bed plates of the machinery if milled from the top horizontal cutter head. If you're looking to mill a 3/8" half round please search in that category, we have a few other options to consider for milling multiple profiles simultaneously. The opposite holds true for half round details, they are milled from the top horizontal spindle, the cutters will come within .020" of the moulder bed plates, they do not have any blend area built into the cutter design, so, if you try to mill a bullnose with these types of blades, you will experience parallel knife edge cuts if the moulding moves during the machining process, rendering the product unsalable.
For knife quoting purposes click to open the calculator below, we have added only the important measurements, just enter the appropriate dimension in the boxes provided. A brief detailed explanation on how to use the calculator is located here. Need some assistance with the dimensions? Print a copy of our fraction - decimal - millimeter chart, place it on the molder to help operators save time and increase accuracy during machine setup.
Thickness = .375" / Depth of Cut = .344" (right blades.)
