Review: Seems pretty good quality to me; milled out a busted cobalt drill bit! - Used the 5 and 6 mm to mill out a broken cobalt drill bit in a Master Lock 930 padlock. Slight damage on one of the flutes of the 5 mm, but come on, I milled out a broken cobalt drill bit! I am very please that it worked at all. Pretty darn tuff end mills. Very good value for the money! So this was a lock on my storage container. It is the very nice Master Lock 930 hardened padlock, with LOTO 410 core transplanted in. The 410 core has 6 pins, 5 of them spools and 1 serrated. When I misplaced the only key, the lock is above my ability to pick, so I drilled it out with success. But then I made the mistake of closing the lock, which likely dumped all of the pins making it impossible to open again. Like a fool, I tried to ream it out using a larger diameter cobalt drill bit while holding the lock in my hand. The bit shattered, cut my hand, and left me with a very nice lock that was toast. A new lock is $35 plus $10 for a new LOTO lock as a core doner. I was able to usd these end mills, in my Harbor Freight mini mill, to mill out most of the brass core, finally allowing me to open the lock. As stated, the 5 mm had slight damage on one of the flutes, but I am satisfied. I wasn't sure that it would mill out a cobalt drill bit at all, but it did a pretty darn good job. IMO, the 5mm end mill is still usable, and I saved a $35 lock. This time I will cut a spare key for the LOTO core. BTW, all this lock stuff is just for Lock Sporting and personal use. :-)
Review: Good value - Good selection of miles. Seem to be well made. Will fit my needs well and are a good value

## Questions & Answers

**Q: What is the warranty on these bits**
A: 10 feet or 10 min.

**Q: can these mills be used in a plunge router?**
A: I mean yes, but coated end mills are more for metals. Wood debris sticks to the coating. You'd also need the appropriate collets and such.

**Q: Are these center cutting end mills?**
A: Yea

**Q: Anybody know how well these will mill lead and aluminum?**
A: They do ok in aluminum. Sticks a little depending on setup and really a 3-flute is preferred.  No idea about lead.

### ⭐⭐⭐⭐⭐ Good value

Good selection of miles. Seem to be well made. Will fit my needs well and are a good value

### ⭐⭐⭐⭐⭐ Very well worth the money. A quality set of rotary bits.
*by A***E on February 12, 2022*

This product worked like a charm and is well worth the money. The individual air sealed packs for each bit are of good quality and will not fall apart are a few openings and closings. The bits themselves feel of good weight and the finish of each bit looks premium upon close inspection. I've used one of the bits for milling wood, sheet metal (steel) and high density Styrofoam. It performed like a champ and seems as good as new. It seems to have maintained its sharpness after usage. The metal milling was only a small piece, around a 2cm run in 4 x 0.5cm bouts in 1mm (3/64 inch) cold rolled sheet metal so no real surprise about it maintaining its "like new" condition however this does prove these bits are the real deal; not knock off items masquerading as quality tools. I'm quite pleased with the purchase and the price point. If the manufacturer/vendor keeps the price point I will definitely be buying more in the future.
