John Clutch Posted August 4, 2015 Share Posted August 4, 2015 Im going to order some tooling, and I was wondering what you would suggest for countersinks. Single flute or multi flute? ThanksClutch Quote Link to comment Share on other sites More sharing options...
Cato Posted August 4, 2015 Share Posted August 4, 2015 Various ball cutters from Dremel make great countersinks in brass, ally and plastic. I use them in a regular variable speed drill. Quote Link to comment Share on other sites More sharing options...

BigTallDad Posted August 4, 2015 Share Posted August 4, 2015 There are also tapered/pointed end bits for Dremels Quote Link to comment Share on other sites More sharing options...
Roadrunner Posted August 4, 2015 Share Posted August 4, 2015 There are also tapered/pointed end bits for DremelsYep, if the material is thick enough, the tapered grinding bits should work fine. Quote Link to comment Share on other sites More sharing options...

I was kinda wondering that myself. I also do woodworking, which sometimes calls for countersinking (typically 1/8" or so) so I was curious how thick the plastic being used was. I've used .040" recently and would never dream of countersinking that. Quote Link to comment Share on other sites More sharing options...

Foxer Posted August 5, 2015 Share Posted August 5, 2015 I use just a regular drill bit when a countersink is needed ... it's a rare occasion for me though. Quote Link to comment Share on other sites More sharing options...
John Clutch Posted August 5, 2015 Author Share Posted August 5, 2015 When possible, I would like to use flat head screws to hold certain assemblies together that can be hidden later. Like holding radiator to the radiator support or something like that. Quote Link to comment Share on other sites More sharing options...

Like holding radiator to the radiator support or something like that.I'm doing the exact same thing right now on the Rolls with 00-90 screws. Made the countersinks in the (thin) steel hinges with the above Dremel small ball cutter. Quote Link to comment Share on other sites More sharing options...

Roadrunner Posted August 5, 2015 Share Posted August 5, 2015 But not for metal hinges.Nope, probably not for that. For plastics and wood it would be great though. I can't even remember the last time I needed to do anything similar. Quote Link to comment Share on other sites More sharing options...

The small starter points are small enough for model building. I use them to countersink the heads of straight pins I use for re-enforcing and pinning models Edited August 6, 2015 by 935k3 Quote Link to comment Share on other sites More sharing options...
