High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 0.75-inches thread length. Applications: Good for steel castings and forgings/heat-treatable alloy steels, free machining stainless steel, heat and corrosion-resistant stainless steel/valve stainless steel, aluminum alloy castings. Excellent for low carbon/free machining carbon steel, medium to high carbon steel.

Use this to tap holes where my other taps were getting eaten alive by the frame I was trying to tap into. I use this with a hand drill to slowly tap the holes and it worked fantastic.

Works great for power Tapping stainless steel, as long as you know what you are doing.

I don't know anything about machining so I can't give an educated review. But if you're like me and you need to tap a few holes, save the $20 on the Harbor Freight tap and die set. I couldn't get their tap started to save my life and I thought it was my technique. Bought this guy and it was easy as pie.

The tap performed flawless in the blind holes. The spiral flutes pulled the chips out of the hole and it cut well. Highly recommend over the standard straight flute taps. Wish I knew about these taps years ago.

I purchased two of these taps to build a fixture table. I needed to thread 135 5/16" holes in a plate of 3/8" thick mild steel. I purchased two of the taps fully expecting to break or wreck at least one. I stuck the first tap in the drill and started threading using basic cutting oil. 135 holes straight on the first tap without a problem. Now I have an extra if the first one ever does go out. It centered easy in spite of being a bottom tap and required no backing process mid thread. The threads were nice and tight as well so it should wear well over time.

YG-1 taps seem to be really well made. This one works well on gray iron, but I have not yet tried tapping anything made of nodular iron (like an axle differential). It seems like I will get about double the number of uses before I am worried about it dulling to the point of snapping off in the hole as compared to my Hanson/Irwin taps. (All my Hanson taps are HCS and I have snapped off a number of them over the years.) Also, the flutes seem to be less deep, so the cross-sectional thickness seems to be greater than what you see on a "normal" four-flute tap. This YG-1 tap cut with ease despite my using a hand tap wrench. (I think this was designed to be used in a mill or drill press.) The price seems to be quite fair for what you get. Recommended.
