Now that you know what a lathe does, you can start creating well-rounded masterpieces of your own. Lathes are highly satisfying and highly productive machines that should have a place in any machine shop.

Milling machine

Mechanical lathes must be powered by human intervention. These use gears to help spin the material at the desired speed but require manual intervention.

These tools make it very easy to create symmetrical objects out of various pieces by rotating a block at fast speeds to remove uniform amounts of material from them.

Drilling machine

While some bits come pre-lubricated, you should always double-check to ensure they have lubricant or cutting fluid before using it. Lubrication dissipates heat, reduces friction, and prolongs the life of the bit.

If you're a good craftsperson and you take care of your tools, then your lathe tools are bound to last a lifetime. There is a need for an initial investment in chisels and attachments, but with proper care, you'll never have to buy them again.

As discussed in this review, ensuring you’re using the right drill bit when drilling metal is essential. Attempting to drill through metal without an HSS, cobalt, or carbide bit will cause it to snap and cause injuries. Additionally, you should consult a speed chart to ensure you’re not drilling too fast or too slow, which could shorten the life of the bit.

Metal drill bits typically have rounded, no-spin, or hex shanks. When determining what shank design to get, look for one that fits your drill’s chuck size. No-spin bits have a fluted shank design and help keep the bit secure when drilling, while hex shanks have six sides that help keep the bit steady.

You should always wear eye protection, such as safety glasses, when drilling, regardless of material. Additionally, avoid wearing loose clothing, and consider also wearing ear protection.

Important safety tips: When using a lathe, always stand slightly to the side of the rotating material. Although you should always ensure the materials are held tight before operating, you should never assume they won't fall off. In the event they do, don't find yourself in the line of fire.

Lathes quickly rotate a block or piece of material and allow you to remove a consistent amount of material around the perimeter of the piece. In woodworking, this is known as "turning".
