Mail your broken drills there, with your name and your previously registered serial number, and they say they’ll mail replacements back. The drills are claimed to have a “Lifetime Warranty”, but of course with a small business one has no guarantee of what lifetime the company will have, during which it will fulfill warranty claims.

An alternate term for the lathe is “turning,” as it is most effective when creating cylindrical parts. Other common operations in the lathe include parting, boring, threading, drilling, OD, and ID grooving. If you are looking for a process to create repeatable, quick, cylindrical symmetrical parts, a lathe is the best choice. You can use it to work on both wood and metal.

Locksmiths would use this sort of drill to drill the pins out of a hardened lock cylinder; a forced-entry method that, if done carefully, only damages the lock cylinder and some pins and springs rather than the entire lockset; allowing the locksmith to repair the lockset after entry. Gunsmiths also drill into hardened steel. I am making some antenna mounts out of 1/4 inch 304 stainless steel. I might also fabricate some space satellite parts for Open Research Institute. Perhaps I’ll find it makes more sense to stick with cobalt for those applications.

Modern manufacturing plants use both lathe and milling machines. Each of these machines operates on a similar machining process called subtractive machining. This is a process that begins with a block of material. The next phase is to shape it according to your desired specifications.

On the other hand, if you wish to drill holes, a milling machine is an effective solution because a lathe can only drill the center of your material as it rotates on a fixed axis. Using a milling machine will allow you to make holes from any direction as well as perform straight cuts.

When comparing a milling machine vs. a lathe, always remember the following differences. If you wish to cut wood or metal that is cylindrical in shape, it is always best to opt for a lathe. This will help you perform the task precisely with easier cutting.

Drill Hog is a brand name of “Canary Island Corporation”, incorporated in Nevada, registered in California and operating in California. The sole officer is Mr. Joseph John Russell, who uses the same address as above. I could not find a California fictitious business name registration for “Drill Hog” (and I am not clear that one is necessary). The business is a “manufacturers representative”, which means that Mr. Russell probably purchases these drills from the actual manufacturer for resale. There is some left-over web presence of what appear to be two previous businesses of Mr. Russell: Something called “tarpsdirect”, and toolprice.com which sold Harbor Freight style merchandise. Their web site appears in the Internet Archive. There is more information about Mr. Russell easily available, but not reproduced here out of courtesy.

Shaping of the material is the key difference between a lathe vs milling machine. If you wish to understand the difference between a milling machine vs lathe, this post is for you.

As a good manufacturer, you need a machine best suited for the type of material and designs you will be working on. So, you must carefully consider lathe vs. milling machine before making a purchase. Are you looking for a lathe or milling machine?

Their prices on eBay are cheaper. Amazon takes an 18% markup, is required to carefully charge sales tax, and often does their own fulfillment (processing the order and shipping). eBay vendors pay less of a markup, may avoid sales tax in some cases, and generally do their own fulfillment. So, always look for the same product from the same vendor on eBay before you buy.

There were some questions online regarding who Drill Hog really was, because so far they don’t have an email or a phone number published. No phone is not unusual for someone’s “side hustle”, when they work another job all day, but I would have preferred to see an email. Drill Hog requires warranty registration at hogwarranty.com . Once you have registered, they service their warranty through this address, which is a box in a UPS store:

There are a few videos online evaluating these bits making large, deep holes in stainless steel, and in the videos they handle that fine. Drill Hog claims that niobium is a specialty drill bit which only works well with certain metals (they don’t say which) and which they usually sell to locksmiths and gunsmiths.

Another difference when comparing a lathe vs a milling machine is the task you can achieve. Apart from the above-mentioned tasks, you can use a lathe for

The primary difference between the two is the tools used in the process.  A lathe uses a tool known as an insert cutter with a removable tip. This insert cutter helps you cut the material and create different shapes.

On the other hand, an insert cutter is not a common feature in milling machines. A milling machine uses an end mill that you can operate at different speeds at different angles for precision.

A lathe is one of the most widely used and versatile machines in the world. A lathe rotates your workpiece on its fixed axis and performs a variety of operations such as knurling, facing, cutting, etc.

Tool steel is not a homogeneous solid. It’s a matrix of hard carbides or nitrides in metal. Alloying with niobium promotes a fine grain of the carbide and nitride crystals and better case hardening, and promotes the toughness, strength, and formability of the steel.

Unlike a lathe, a milling machine operation involves the machine rotating about its axis without rotating the workpiece. This allows your tool to approach the workpiece from a different angle in many orientations to create more complex and intricate parts.

In simple terms, if you wish to cut material at angles and intend to work on various non-cylindrical materials, a milling machine is the best choice available.

A milling machine has cutters that rotate to reduce the material used to give it the desired shape. Nowadays, the milling machine is one of the common tools factories use to create products of different shapes and sizes.

Besides their own brand, Drill Hog has sold some Norseman drills. Norseman is a well-known source of high-quality drills. Drill Hog’s house brand drills look like copies of Norseman drills, with the same thin web (the metal between the two flutes) and similar details to the machining of the bit. They are marked “USA”. Mine came packaged in a black plastic canister which seems to be a knock-off of the one Norseman sells – a slightly different shape and different color.

I purchased a set of niobium steel drill bits from “Drill Hog” The price was good, and I was interested in whether they’d work better than cobalt for some applications. Cobalt drills are known to be hard, but quite brittle. I’d use either kind of bit only in a drill press, if at all possible, and only with cutting fluid. I would in general use less expensive high-speed steel drill bits in a hand drill.
