Review on 🦷 Yibuy Tapered Modulus Teeth Degrees by Bobby Martinez

Hole NOT 14mm

I bought these to fit my drill press shaft which measured exactly 14mm (5.50 inches) with my calipers. I know 14mm is a very unusual shank diameter, but my Wen drill uses it. The hole on it is less than 14mm and it won't slip even with a little persuasion. I have not tested them on 13mm or 1/2" (12.7mm) shafts.

Pros
  • Gears
Cons
  • old
