Countersinks
We stock Carbide and HSS countersinks in Single Flute, Three Flute, Four Flute, and Six Flute configurations to match different material and finish requirements. Single flute countersinks tend to produce a cleaner cut with less chatter in softer materials, while multi-flute versions offer smoother performance and longer tool life in production settings.
Carbide countersinks hold their edge longer in steel and stainless applications, while HSS remains a solid, economical option for general shop use. All countersinks are manufactured in the USA and typically ship the same day.
