This is the size required to drill holes for euro hinges. Like all Freud bits I have purchased this bit is very sharp, does not wobble and cuts like a pro advertised clean holes. I'm happy with his work and you can't beat the price. Specialty bits for euro grinds are $75-$125 and usually have carbide tips. If you were making kitchen cabinet doors and drilling hundreds of holes a week, this would be necessary , but in my small specialty shop I only occasionally install euro-hinges and this bit works for me, the day after it won't cut clean holes anymore and that's not a bit for man made materials ie MDF, plywood, chipboard, I only use it for hardwood -Styles - HSS won't get far in MDF!
