Usillo para coronas de 14 a 30mm
Tenía un usillo makita y, a pesar de que la rosca era la misma que la de la corona starrett, la broca no era lo suficientemente larga. Éste sirve tanto para coronas makita como starrett

Quality arbor
Good arbor. I have primarily used this on starrett holesaws drilling through wood & plasterboard, but recently put a 32mm hole through mild steel. I was surprised how easily the drill bit went through the steel & it still looks like new. The quick release mechanism is great but has a small downside. Sometimes it tends to pop out, & if you dont notice & carry on drilling holes, you end up with the arbor stuck tight on the holesaw, requiring adjustable spanners to crack it off.
