I need a small countersink and am having a hard time finding ones for small screws . BVM and Dreamworks used to sell a countersinking bit, but its not available anymore. If anyone has any extra I'd be interested in these ..

Also, would anyone have any idea otherwise where else to go looking for these ? It would be nice to find various small sizes as well if they are available anywhere .. I have a project where i need to countersink hundreds of screw holes, any info would be great ..

thanks guys .,

Small countersinks are easy. Just get them from an industrial tool shop.

What size screw are you looking for?


look here:

I normally use a ball style rotary file from robart that is the same diameter as the screw head

I use diamond rotary files and these are available in box sets with loads of other tips to suit a host of rc hobby jobs - great on composites and cheap.
If you want a specific product specifically for coutersinking then the best are from Permagrit - who do a huge range of brilliant products.

You can get these perma-grit counter sink tools at BVM still.

Tony hit it on the head. I use the combination drill and countersink for most all because it gives me a bit of control on the depth. If you have a Harbor Freight around they have them and would be good for FG and ply but they don't stand up to stock like SS or high carbon very long. Chicago Latrobe on the other hand will stand above all.

these guys have about anything you might need .mscdirect.com/

Yep. Have ordered from them and they carry all the name brands as well. By the way K12. Happy Fathers Day to ya and all the bunch here on RCU.

Lots of good links , thanks guys !! This is the one where I found what I need ... MCS also has a lot of stuff i like ..

I have the permagrit ones, however i can not risk grinding through what im working on. I need the precision of a fluted metal tip ..

Why do you guys need a small one. As long as the angle is right you can use one of any diameter, no?

A small one is easier to gauge depth with ... basically take it to the brim, and its just right ... i will be sinking probably over 1000 holes, and going too deep is not an option. Its not like i can do touch up work on aluminum easily . I have some larger ones i have used, but on practice material, i just don't have the precision if feeling the depth out ( and eventual width of the sink )

msc direct was checking there web site saw some as small as 1/16 dia

A larger one also has a larger shank usually. Could make a hole that's too large for small screws

OP, have you looked at McMaster Carr's web site?
