My father is a contractor and has very high standards when it comes to tools. After using this drill bit, he said it’s the best one he’s ever had! The color is beautiful, and the craftsmanship is top-notch—it feels durable and well-made and nice job on the rust prevention.In practice, it drills efficiently and precisely, with no jamming or overheating issues. As a seasoned professional, he’s thoroughly impressed with this product.Highly recommended for anyone looking for high-quality drills!

I’m gonna give you boys, a little tip here that will hopefully change the way you drill things. First and foremost, slow the hell down! If you must drill your piece by hand (and not in a drill press, etc)..,, by God, get a drill /speed rpm Chart and go by the rules religiously. Don’t, put the thing in High gear, with no clutch setting, at 19,000rpm and have your buddy Wayne get the floor jack under the “Crapsmen” cordless drill to drill a 1/2” hole in your 95 ratted out 12valve Dodge. Mkay?! Great. Next, fluid.KEEP IT COOL! Get yourself something to put on your piece or bit. CRC makes a fairly good aerosol for this for field use. Huge difference in making your drill bit last. And the time it takes to cut through your piece. Also, don’t forget that the type of metal your drilling, will determine your speed of your drill bit. Here’s to hoping you don’t break your wrist Randy, on your next hillbilly adventure with drills, and bits!! Good luck! 👍🏾

It works very well! It drills through 1/4 inch steel plates easily and chips evenly, which is exactly what I needed!
