Drill America - DWT57129 1/4-20 High Speed Steel 2 Flute Spiral Point Tap, DWT Series

Works great.

originally bought the Dewalt package, which is really, really hard steel & it snapped in the hole. Now this is a really small screw in a lawnmower, holding the transformer in place that sparks the spark plug as the magnets float by, so I couldnt go bigger. Used a grinder to make an [X] on top center of hole & titanium impact bits from Harbor Freight to cut the initial hole & break bit. The larger grooves & some PB blaster, allowed the metals to collect as I turned the new tap, so I could screw unscrew, blow out/wipe & repeat, until the hole was clear for a new screw to go in. Dewalts pack, just didnt have deep enough grooves for the metals & snapped when I was unscrewing, which was likely my fault. But this bit allowed me to go deeper, so it was quicker & a better choice for my project.

No

works as advertised

I had 4 of them. All did excellent job for my business. Thanks

I liked the concept but both of the taps broke when I first tried to use them. I used the #7 drill bit supplied by the same company too. I used tap magic religiously and tried not to force the tap while breaking the chips... definitely a waste of money. At least the drill bits are holding up since they are suppose to be m42 cobalt steel. Now on the hunt to find a different brand ¼x 20 tap.

Working in an elementary school, I discovered that the adjusting screw for desk legs that had been used werent really the right size. Turns out there was no right size, but this tap made short work of producing a tapped hole that perfectly fit the available screws.

They work well.

Put threads in a piece of metal

Good tap. Labeled as HSS. Tapered with two flutes, bright HSS. Cuts fine. No country of origin on tap or package that I can see. Good deal for the price.
