Helpful Quote from Video Transcript:

"The selection of a cutting tool is probably the most important decision a machinist can make. We are going to cover some of the basics, but I urge everyone who intends to use the lathe, to learn as much about cutting tools as possible. They are the key to the quality of your work. Lathe tools are made from many different types of materials, in many sizes and styles. The three types we are using today are, from the left, high-speed steel tools, carbide-tipped tools, and on the right, carbide-insert tools."

The machine that Dave is using for demonstration purposes is the Granite MAX 1324. This lathe-mill-drill combo machine sets the standard for premium quality bench top machine tools.

Putting a combination machine tool in your shop allows you to have the capabilities of a small machine shop without sacrificing too much floor space.

The Granite 3-in-1 “big machine” features and premium quality is comparable to other larger, more expensive machine tools. PLUS, you'll have three machines in one.

Nearly 30,000 Smithy machines are working hard every day in shops across North America. This fact let's you know that Smithy machines do set the standard for quality.

As Close As You’ll Get to American Made

1) US Developed and Designed: The Granite Machine was designed by our engineers in Ann Arbor, Michigan based on machine user requests.

2) Precision is far higher than other 3-in-1 knock-offs: All components are machined to tighter specs, bearings are much higher grade, and the basic design is initially higher precision.

3) Higher Quality Production: Smithy employees oversee the production and quality control process at our sister factory of more than 25 years. No other seller can make that claim.

4) Superior Features: No machine out there can match the speed and accuracy with which you can accomplish your machining tasks on a Granite machine. Other 3-in-1 combo tools on the market are NOT EVEN in the same category for quality as the Smithy line of machine tools.

More from the Video Transcript:

"High-speed steel tools can be used on many turning operations, on all but the toughest alloys. The tools are sold as blanks in many sizes and grades. The machinist grinds the point of the tool depending on the type of metal he is cutting and the type of turning operation he intends to do. A good machinist's handbook will give you the standard guidelines for grinding high-speed steel tools. "

"The cutting edge of a carbide-tipped tool is brazed to the end of a steel shank. The shape of the cutting edge, it's profile and cutting angles, are manufactured into the tool. A little cleanup on a green wheel, a silicone carbide grinding wheel, and the tool is ready to go. Cemented carbide will handle much more heat than high-speed steel, so carbide tools are able to cut tougher metals, and cut at higher speeds."

"Cemented carbide is also used to make small inserts that are clamped to a tool shank. This style insert is manufactured with a cutting edge on each of its three sides. After an edge is dulled, the insert can be unclamped and rotated to the next side. After all the edges are dulled, the insert is thrown away and replaced by a new one. Although this type of cutting tool was designed for the demands of the high production work, it's really a great tool for the beginner because it allows even the person with little or no tool sharpening experience the ability to easily maintain a properly formed, sharp tool.
