A COVID Housebound Project
The Lyman Case Prep Center is great. The reamer tool is a must when decrimping cases like LC. But, they're $10 each and I find they wear down quickly.
So I got some 4.4 mm drill bits from Amazon. A 5-pack was $6.89. I filed the point flat so they wouldn't drill out the pocket. They worked good in a drill.
But, I wanted it as an attachment to the center. So I cut the bit short and cut threads with a 8-32 die. Works great. They measure .170 so they don't fully open the pocket to SAMI size (.1745-.1765) but they open it enough to go on to the pocket uniformer tool without the case binding.

If you cut threads on the bit what kind of steel is it? even being able to "file" down the tip
