I have a small shop and I always rely on drilling adjustable shelf 1/4'' pin holes with my own templates. My problem is I'm always trying to find a reliable 1/4'' shelf pin hole drill with stop collar that will not fail. There are lots on the market and I probably tried all so I wanted to contact you the group and see if anyone knows of a really good and reliable 1/4'' shelf pin hole drill with stop collar. If you have a link please include it. Thank you!

Cut a piece of 3/4" x 3/4" scrap the length of your chucked drill bit minus your hole depth and template thickness, drill through the center lengthwise and keep it tight against the chuck in use.
Long, shop made stop that can't fail

Assuming you've tried vix bits? We have some issues with them sticking on occasion but a little spring modification helps. Youd have to adjust your template but rocker has a nice spring loaded drill that runs Brad points but it registers on a larger diameter hole for their fixture. We use them for various drilling setups but we make templates on the cnc.

Rockler makes several really great jigs for this purpose and Woodpecker makes a fantastic jig also. If you are going this as much as you indicate,invest is a dewalt 1/4 plunge router 611 i believe, get a jig and help yourself

Jack Mazz, I like the plunge router idea. Its one seen before but it escaped my mind. I actually have everything in the shop including two new Mikita one horse power routers with plunge base. I'm not sure if I have a collect but I should have everything already in the shop. The plunge router should make a cleaner cut.

And thank you everybody for your input and especially using the drill chuck as a stop. Very cool group!!!

Buy the best brad point you can find. You can buy industrial carbide bits for drilling machines that will work in a hand drill. You can buy a stop collar at the hardware store. A line drilling machine will pay for itself in a year, unless small shop means hobby shop.

I did what Mark suggested decades ago. Can't fail.

I've also ground the drill bit down some because I think the hole is too sloppy for the "spoon pins" I use regularly.

I just chuck it up in a drill press and use a 220 grit sandpaper glued to a board and rub it against the spinning drill bit to resize it. Each time you do a pass drill another hole until the pin is snug to your liking.

Thank you Leo with that great point. Yesterday I have all the equipment need including the plunge base when I purchased two 1 hp Mikita routers last year. I think I'll just plunge base for a while. I think a line boring machine is out in less one day I should feel the need to spend a lot of money for one that would only add more clutter to my small shop. Thanks again group!

The festool track with system holes and the router setup with spring loaded plate is a good way to go .

I used to do a lot of job site builtins with this set up and it was both fast , accurate and adjustable .

It will set you back about 1200.00 or so but we'll worth it as the parallel and square holes to the work surface make it worth it .

It is very fast as well.
