Kodiak Cutting Tools KCT140270 USA Made Solid Carbide Drill Bit, 2 Straight Flute, 3/4" Length of Cut, 2" Overall Length, 1/8" Diameter

It should be noted that this was used in an unrelated context. non-standard, standard Application that is highly recommended. When removing a broken M6 bolt from an automotive serpentine belt assembly, I snapped a standard (HSS) drill bit. Bolt was in a situation where he needed to gain access to the internet. There is only about 8 inches of clearance in this tight space. I tried to drill out the broken drill bit with Dewalt cobalt drill bits, but they just turned into mince meat. I ordered this KCT bit, and it went right through everything (the broken drill bit, the broken bolt, and a piece of aluminum bracket-- as if they were made of cheap plastic) at the same time. I'd never worked with a solid carbide bit before, and I was completely taken aback. br>br>I was aware prior to purchase that carbide bits should not be used with hand drills due to their brittleness. Having said that, I used a hand drill, and the bit's tip did become chipped as a result, but that's fine with me. This $20 investment in my sanity and time was well worth it, and I'd buy another for the same purpose if I needed one. This is a true lifesaver.

It was a huge success. I started by drilling a small pilot hole with a regular drill bit, then switched to the Kodiak straight flute. It took a little while to get started, but once we got started cutting and burring, everything went smoothly. I tried every drill bit I could think of, including a cobalt bit, and this one outperformed them all. Once I had a deep enough hole with the straight flue, I was able to easily fit an extractor inside the broken end. Finding the right drill speed, in my opinion, is crucial. This is an excellent resource. I'm not going to lend it out because I'm afraid it won't come back!

As a machinist, you should completely disregard him. These bits are only designed to be used in mills, drill presses, lathe tailstocks, and other rigid holding devices with mechanical feed (no hand drills). These bits can cut through hardened steel and are frequently used to extract snapped drill bits from steel. These bits are good, but I don't have the technology or the foresight to split them in half and analyze the carbide to tell you how good they are. If you need a bit that will cut anything other than diamond, this is the one to get. It's 15 bucks and solid carbide.

Because I work as a Toolmaker/Machinist, I've had good luck with these types of carbide drills at work, so I bought this one for home use based on the reviews, and BOY. I'm glad I took the chance. In the heat treated column of a micro drill press, I found a broken off 1/8" hardened dowel pin. I wanted to get it out and tap it for 8-minutes because it had broken off just below flush. As a safety down stop, a 32-machine screw was used. br>I put it in an old small bench top drill press to check for run out. I got it to run within a few thousandths of a second, then turned on the drill press. Around 1500 RPM is estimated. For added rigidity, the shaft was held in a vice. I CAN'T BELIEVE HOW THOUGH THAT DOWEL PIN IT ATE. A dowel pin's center is 48 millimeters in diameter. The inside temperature is 58 Rockwell C, and the outside temperature is at least 60 Rockwell C. The ultimate test for a carbide drill bit is to make it very, very difficult. When it reached the dowel pin's bottom. WITHOUT BREACHING THE DRILL BIT, the rest of it began to spin and jammed the spindle, causing the drill press to stall. HOLY SH- BATMAN ! I've decided to purchase this item. I removed the drill bit from the press and turned it off. The mission has been completed. The drill bit is still functional! This is a CARBOID BIT OF THE HIGHEST QUALITY. BUY IT RIGHT NOW!.

I was skeptical after reading the other reviews. That is no longer the case! I'm almost 70 years old and have completed a slew of home improvement projects. Nothing I've ever owned has ever worked as well at drilling a hole as this one. I'd already broken and chipped several cobalt and "carbide tipped" bits on my current project. I was drilling about one hole per bit on "common" steel angle that had been hardened by welding on it, and I was "averaging" about one hole per bit. I ordered a 1/8 and 1/4 bit from Kodiac out of desperation and am extremely pleased with the results. The remaining 23 holes were drilled without difficulty. First, I drilled a 1/8 pilot hole, then a 1/4 pilot hole. CUTTING OIL SHOULD BE USED! Maintain a moderate amount of pressure while rotating at a 400-rpm speed. The range is 600 rpm. Just keep an eye on the chips as they emerge. The bits are incredible. I'd like to own the entire collection! I'm at a loss for words to express my gratitude! Made in the United States of America! There will be no Chinese nonsense here!.

Part of my job entails rendering customers' old hard drives unusable for data recovery. Drilling holes in a disk drive's rotating disks (and controller ICs) is one method of accomplishing this. The disks of a hard drive can be surprisingly difficult. Regular drill bits will quickly be blown out, but this bit will get the job done.

Aaaaaaaaaaaaaaaaaaaaa When I broke two extractors in a spindle while attempting to remove a broken bolt, I assumed I was done and that the spindle would have to be replaced. This bit ate through the extractors and spit them out, freeing up space to work on new threads and save the spindle. Now, I bought a backup because these bits can be damaged if not used properly, and I'd rather have one on hand in case I ever run into another situation where I need this magically piece of save my ass.

I had to drill a hole in the broken stub of a hardened bolt in order to use an E-clip. To get rid of it, press the Z key on your keyboard. Drills made of HSS or cobalt would just scratch the surface and eventually burn up. I ran this drill through a drill press at 430 rpm with cutting oil and moderate pressure. This product was created in the United States.
