Perma Grit Bits

Does Perma Grit make bits with 1/4" shanks?

Looks like 1/4" shanks in the photo.

Thanks Mike,

Those are the ones I have and they have 1/8" shanks.

I guess I'll have to get 1/8" collets.

Fibreglass and perma grit

I saw on the Perma-grit website and they have countersinks available. I was not proposing using them on metal, but rather on the fibreglass wingtips etc.

My question is which one is the correct size for counter sinking to accommodate the screws on an RV9 ?

My guess is 3/32 with #19 pilot, but can anyone help me out here with the correct sizing ?

Thanks
David
