Sharp!
I have a Jeep JK, and as every jeep owner knows the two piece OEM lug nuts are trash. Eventually, they will go, and when they do you will be cussing. Five lug nuts across both front wheels had the chrome cover separate, and rounded off. I put a breaker bar with a nut extractor on them, and they broke off leaving the base. Nothing to do at that point but drill the studs out. I went to the big box store L***s, they had the Dewalt Elite cobalt drills, and I bought some to use for this job. They were great, but the store is way overpriced. These bits do not specifically say "Elite" but they are in all respects identical appearance wise. These bits claim to be cobalt, and they are, and they are also a great value for the money. No they didn't go through those studs like hot butter, no bit will, but they did leave 6 inch long spirals of the steel they were cutting. Sharp. They got a tough job done with a minimum of fuss. I used Tap Magic to keep them cool, and it did the trick. The bits stayed so cool I could touch them to the back of my hand when I removed them to add more Tap Magic. I also went slow, these bits didn't really like VERY slow, so I adjusted my speed as fast as they would cut, and stay cool. They have a sweet spot, you will have to find it. They only gripes I have are the smaller bits dont clean out well, so I had to periodically pull them from the stud and spin them fast to throw off the metal chips, usually when they stopped cutting because it was clogged. And if Dewalt has a .5 inch bit like these I couldn't find it. Get them if you need good bits for steel, you wont be disappointed.

Robustes Bohrer-Set für Metallarbeiten
Das DEWALT 14-teilige Cobalt-Bohrer-Set macht einen sehr soliden Eindruck und eignet sich besonders gut für Arbeiten in Metall. Die Bohrer wirken hochwertig verarbeitet und schneiden auch durch härtere Materialien wie Edelstahl oder Stahl recht zuverlässig. Ein großer Vorteil ist das Cobalt-Material, das für zusätzliche Hitzebeständigkeit und Langlebigkeit sorgt. Dadurch bleiben die Bohrer auch bei längerer Nutzung relativ scharf. Die verschiedenen Größen im Set decken viele typische Anwendungen in der Werkstatt oder beim Heimwerken ab. Die Aufbewahrungsbox ist praktisch und sorgt dafür, dass die Bohrer ordentlich sortiert bleiben. Außerdem lassen sie sich leicht entnehmen und wieder einsetzen. Ein kleiner Nachteil ist, dass die Box etwas stabiler sein könnte. Bei häufiger Nutzung wirkt das Kunststoffgehäuse etwas einfacher. ✅ Vorteile • Hochwertige Cobalt-Bohrer • Gute Leistung auch bei Metall und Edelstahl • Mehrere Größen für verschiedene Anwendungen • Praktische Aufbewahrungsbox ❌ Nachteile • Aufbewahrungsbox könnte stabiler sein Insgesamt ein sehr solides Bohrer-Set, das sich besonders für Heimwerker und Werkstattarbeiten eignet, wenn regelmäßig in Metall gebohrt werden muss
