1/16" Roundover

ID: H05

The subtle one next to H02 and H03. 1/16” radius barely reads as a roundover at all: it’s an edge break, not a profile, for taking the sharpness off a corner without visibly rounding it.

Notes

This is an edge-break bit, not a decorative profile. Compare the 1/16” radius here to H02/H03’s 1/4”: those round a corner enough to see and feel as a curve. This one just knocks the sharp edge off so it doesn’t cut skin or chip under handling, on parts where a visible roundover would be wrong.

Quadra-Cut geometry, per Freud, is built for clean cuts going against the grain as well as with it, so this one shouldn’t tear out on cross-grain edges the way a simpler two-flute bit can.

Freud’s own tip: swap to a bearing 1/8” smaller than the stock 1/2” to turn this into a beading bit instead of a roundover, since the reveal between bearing and cutter is what makes the difference. Worth remembering if a beading profile is ever needed and there’s no dedicated bit for it.
