I ordered for will call but was told it was not in stock and would have to be mailed from california for the cost of postage which I agreed too. This is a small one inch long x 3/8 dia item which should have been less than $3 to ship. instead I will billed over $6 which was abougt half the cost of the bit. Seems there is a minimum that I was not told about so disappointing.

Q: Do both 3/8" and 1/2" inch diameter counter sinks fit in the micro-stop?

Per the supplier: Yes, 12-00879 would be the correct size cutter for 3/8" and 1/2".

Q: Can I use these Micro-Stop countersinks with 4130 steel?

Per the supplier: yes, it can work on 4130 steel, but it will wear out the cutter a bit more than what it is designed for (aluminum). We also suggest to use some type of lubricant for the 4130.

Q: How do these products work with lexan?

These are designed for aluminum. They might work with lexan but we recommend trying it on scrap first to may sure.
