Description of Forney 20992 Bottom Industrial 2 Inch
Unified National Coarse (UNC). High speed steel (HSS). Includes 30-degree chamfer angle. Approximately 2 pitches chamfered and 1-1/2 tooth height. Used when threads need to go to the bottom of hole.
I opened the envelope and looked inside. Below were two taps without any protection. What the hell? They are very boring and worth nothing to me at the moment. I will request a refund. Cutting tools must have cutting edge protection, otherwise they will become blunt.
