plans for countersinks, June 2024

I'm looking to get a small set of these countersinks:

• KEO Cutters [offsite] [offsite]
• HHIP
• (TODO: add more manufacturers. These are variously known as "cross-hole", "Weldon style", or "zero flute" countersink bits.)

The end goal is to build a container of my own that's similar to this.
