Thread tap suggestion

[Lil Giants]

Spiral point tap is what I have, as I notice the chips being pushed forward. Using it for a blind hole is time consuming & the necessity for pressurized air to clean the hole often, as well as drilling a deeper hole than necessary. Need to get a "spiral flute" tap for blind holes.

Gosh it's GREAT having a journeying machinist on the forums, learning lots. Thanx for taking the time to edumacate us.

I haven't looked far and wide but the options at McMaster Carr are limited in the small taps, ex. 1-72. I think the real options for the different types of taps start at 2-56. I may have to expand my buying horizon to MSC though.

I do have a tapping fixture from MicroMark which helps with using small taps.
