How to select the right countersink for a job?
Match the countersink angle to your fastener head angle — 100° is common for metric flat-head screws. Choose flute count based on material: 3-flute designs like the CHICAGO-LATROBE 56878 reduce chatter in steel and aluminum. Ensure body diameter clears the hole size without interference.
