Through trial and error, I found that this arbor works great with my drill chuck .It`s easy to install and holds tough when drilling through materials. The quality of this arbor is top-notch and it's durable enough to withstand heavy usage. The only downside is that IT'S a bit pricier than other arbors on the market. Overall a great investment for those in need of a reliable arbor..
Ordered the wrong size and it's so cheap it's not worth returning - also nice to have as I'll have a router to match one day. OK, I can really dream ;-)
