Notes
Cross-referenced the same way as K01: Grainger’s item number (45FA42) doesn’t match anything in MK Morse’s own catalog directly, but selecting 5/8” diameter on MK Morse’s own “CT Hole Cutters: Shallow” product page returns model CTS10 with the same 3/16” cut depth Jon read off the physical bit — confirms the identification even without Grainger’s page loading cleanly.
Teeth count and pilot drill dimensions are unconfirmed on this one. K01’s spec came from a fully-loaded Grainger page; this one hit Grainger’s bot-detection wall before those fields could be read. Same cutter family, same construction, so likely close to K01’s spec at a smaller diameter, but worth confirming directly off the physical bit if it matters for a specific job.
Price not confirmed for the same reason — Grainger’s page didn’t load far enough to read it.
