A 1.5 mm ER collet will not close down 0.040", the latter will not fit in a 1.0 mm. Solution? A 3/64" ER-32 collet will collapse to hold 0.040", at least it works that way with the ER-16s I have. Maritool has them, it will run you $22.34 plus shipping plus tax, they take PayPal if that matters.

Martin ________________________________ Have you considered using a pin vise? I have successfully drilled M3 threads. I put the tap drill into a Pin vise and then into a regular milling machine. My 3mm tap drill does not come out of this pin vise. Since I have multiple pin vises, this does not bother me. I read a description of how some German machinists worked to create 1/10, 000 mm parts. The important thing was the cotton gloves to avoid putting fingerprint oil on their parts, and wiping things down with alcohol to clean them.

OTOH, I do have some cherry or mahogany scrap I could make an open top box out of. humm... Might just work. Different approach, I like. Thanks Roland.
