Source for 10mm dia. drill bushing?
« on: May 18, 2019, 12:15 PM »
Does anyone know a source to get a 10mm dia. drill bushing?

Edit: Something like this: http://www.leevalley.com/en/wood/page.aspx?p=40089&cat=1,180,40089

Found this, but the shipping cost is way too much for this Canuck: https://www.ebay.ca/itm/GRAINGER-APPROVED-Drill-Bushing-H-Drill-Size-10mm-H406JZ/312587351443?hash=item48c7a87593:g:uzoAAOSwZ3lcxCpA

Looks like your only option is to buy a 3/8” bushing and a 10mm ream and hope it works.

If you try that probably need to start with a tapered ream (possibly from both sides) and follow with straight.

Try Carr Lane, they manufacture all sorts of manufacturing and fixturing items. They're pretty much the standard in the manufacturing arena.

Here, I just found a straight press-in version.

https://www.carrlane.com/en-us/product/drill-jig-bushings/press-fit-bushings/press-fit-bushings-metric-pm/pm-15-12-1000

They're also available in 10.2 mm and 10.5 mm bores.

Here's a headed version.

And here's a replaceable version.

If you mean internal diameter couldn't you pilot drill out using a bushing (so the hole doesnt elongate and lose accuracy) to a smaller size then final drill it at 10mm?

Thats what we used to do at a local engineering company on the parts that didnt need to be full on machinists accurate

Bridge City Tools did have metric bushings when they were in business. I know someone bought him and out.

There are plenty of “10mm bushing” available but none that I’ve seen that are interchangeable with a press-in “mother bushing” like what the OP linked at Lee Valley.

So, what exactly does “like this” mean?

BCT is still in business under new ownership, Harvey Industries, but still known as and found under the name Bridge City Tools. John still designs tools etc.

Thanks, everyone, for your inputs.

My plan was to get a 10mm bushing as I already have a set of LV's metric bushings. Upon inquiry, the vendor that supplies LV's bushings advised that it no longer produces 10mm bushings due to issues related to the bushing wall.

I now managed to find online a steel tube of 10mm ID for a just a few bucks, and will use it to make a jig, so I can use my DF500 like a DF700 (up to 10mm x 24mm x 100mm dominoes) in a more structured manner.

Previously for one table project, I used the DF500 plus a drill bit/bushing to use the 8mm x 22mm x 100mm dominoes in a two rows of double-mortises joinery. This time for another table project (a single row of double mortise joinery), I would make a drill jig for using the 10mm x 100mm ones after the mortises are precut to 50mm deep with the DF500.

Yea it all depends upon the duty cycle. If it’s a non-critical application where you’ll be drilling 40 or fewer holes and they only need to be located within a +/- .010” positional tolerance, the non-hardened drill bushings are fine as they are not really guide bushings but rather just drill guides.

If it’s a repetitive process for hundreds of parts and the positional tolerance needs to be within a +/- .002” range or less, then hardened drill bushings are required. Given of course the jig/fixture you've created is even capable of holding the tolerances you need.

Thanks for the ebay link. Ordered one such set even though I have already placed an online order for a 10mm  ID steel tube.
