Comment on WHY???

Did not know that so I looked on Google.

AI Overview That statement is incorrect. Drilling a countersink bit into plywood (or any wood) produces a smooth, conical hole, not a hexagonal one.

Followed by every article talking about why the bits make hexagons, with videos and pictures.

Haha I love AI! We’re so close to AGI I swear bro!

Interesting, I’ve only had the hexagon thing happen to me in plywood, but it seems it can happen in regular wood as well.

  Presumably to do with vibrations at a harmonic of the RPM?

    Yeah apparently it has to do with the bit sort of sliding in behind the holes it carves out with its blades. Doesn’t happen with a regular drill bit because those don’t have sticky-out parts.

Incredible.

When my drill bits are super, super dull, they make smooth triangles. Like triangular shaped holes, with no true points or flat edges. If I get crooked while laying on it and drilling (not uncommon with a dull-ass bit) two lobes will stand out more clearly than the side I’m not leaning towards.

Not hexagons, and sure as hell not cones.

Now if they’re sharp, it’s just a fucking hole. Circular. Like they’re supposed to be

Buy me new drill bits. for science
