Cleveland Blade Tap Chasers 3-1/2-12 UNS TiN Coated

Got a set of Cleveland blade tap chasers here. These are 3-1/2-12 UNS with a titanium nitride coating. They're for an M-83 nose piece, 6 in a set. Box is a bit worn but the parts inside are what matters. Made in the USA back when things were built to last. Not sure if anyone still uses these specific ones but figured I'd post them up for someone who needs 'em for their shop.
