I am looking for some specific drill bits. I have found one company that sells them and I trying to poll the collective to see if there are any other makers of these drill bits that offer them at a bit cheaper prices. Here are the details. Right Hand Drill Bits Carbide Tipped 145 degree negative tip If you havent figured it out these are for drilling into broken easy out's. The easy out's were obviously being used to remove a broken stud/bolt unsuccessfully. The prices I have been quoted start at about 40.00 and go up from there. That is per bit. TIA | ||

dgisupply had some carbide tipped drill bits but the tip and degree were only 118. enco.com seems to be a digital audio company. couldnt find anything related to drill bits. | ||

Go to this page: https://www1.mscdirect.com/CGI/IMLOGIN?PARTPG=IMSR CR and create a MSC customer account if you do not already have one. Then ask them to send you "The Big Book". It is about an eight pound catalog of almost everything you would ever want or need in a machine shop. They have drills. Man, do they have drills! The 145 degree drills have a "sharper" (more acute angle) on the cutting blades than the standard 118 degree drills. That makes the point want to penetrate better at the contact point and wander less. Start drilling on a centered punch mark if you can. Carbide drills are harder and cut better but are much more brittle than high speed steel (HSS). If you are drilling with a hand held drill motor, carbide drills are a little prone to shattering. Carbide drills are best used in a ridgid setup like a good drill press or milling machine and with the work clamped down or in a vise. Good and cheap are mutually exclusive. But MSC's prices are about as good as you'll find on quality tooling. And they generally have the stuff in stock and ship quick. Another good place to buy good quality tooling at good prices is on eBay. There is a lot of good surplus tooling there but you generally have to know the tooling and brands and how to spot good tooling. Resharpening drills is easy and makes sense if you are using a lot of them. From about 1/4" or so and up, do it hand held. For anything smaller, a drill sharpener is generally needed. If you are not resharpening, some of the Harbor Freight drills are okay on a use them until dull and throw them away basis. In the situation you describe, and working hand held, I would generally use a carbide burr in a Dremel tool (or high speed miniature tool and die grinder if you can use air tools) to remove the broken easy out. But a good quality, HSS, split point drill should cut on an easy out. If an easy out will not turn a broken stud easily, I prefer to use a carbide burr to create a small hole, as perfectly centered as possible, on the broken stud and then drill the stud with increasingly larger drills. When your drill is close to or at the tap size, you can work on picking the remains out with picks, punches, and a tap. Jack | ||
