Unlike my old ones these do spring back after drilling, so far so good

I liked the instant center alignment feature that I used to help me install drawer slides. I used the smaller 7/64” for #6 screws. I wish there was max depth adjustment but no big deal. The bits are replaceable when needed.

Ive only used this for 4 hinges but I can say it does it's job. I have a woodshop so I know tools and not gaving this is a pain. This is used for one purpose and it does its job very well. The bits are sharp and there is a small amount of depth adjustment. I'm happy.

These are the best answer for doing door hardware, I always had the larger ones for commercial hardware now I have them for residential also.

Seems to be good quality. Drill is sharp and does not bind in the sleeve.

They work as designed and allow for drilling of well-centered holes in hinges and similar brackets. They aren't as smooth when plunging as the more expensive versions, like I have at work, but these do very well considering they are a fraction of the price.

Compre este juego de brocas auto centrantes y me resultaron muy útiles y me han facilitado el trabajo. Cumplen con lo ofrecido en la pagina de venta a diferencia de otras que pedi:https://www.amazon.com.mx/gp/product/B09BNN94QW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Much better quality than the last set I had. The countersink could be larger for me but it does work.
