300 Below’s cryogenic treatment process is applied to musical instruments and the components used in manufacturing them, which touch and affect both wood and metal used by professional Luthiers while crafting new guitars and manufacturing other musical instruments.

A person professionally trained in guitar manufacturing is called a Luthier, although luthiers typically create other stringed musical instruments as well.1


Cryogenic processing provides substantial benefits both for the manufacturing organization, and for the end user/consumer.

How do companies in the manufacturing industry benefit from cryogenic processing, and what are the primary benefits of 300 Below’s cryogenic treatment process?

  • Longer lasting metal tools used in manufacturing
  • Reduced downtime from fewer change outs
  • Increased operating margins from reduced tool cost
  • Increased manufacturing throughput
  • Reduced tooling costs to meet tight budget constraints

Aside from manufacturing applications there are also several benefits for the end user, when treating guitar strings with our technology.

How do metal guitar strings improve after cryogenic treatment?

  • enhanced tonality
  • consistently maintained pitch
  • an overall brighter sound
  • reduced corrosion

300 Below also improves many tools used by the guitar industry to manufacture guitars, both in the context of hands-on tools used by individual craftsmen, as well as CnC machines used in mass production.

For manufacturers who choose to use carbide tipped tools and inserts, 300 Below offers substantial gains. Carbide typically yields a 300%+ improvement in life after having 300 Below’s one-time irreversible cryogenic process applied to it.

What common tools are used by luthiers to make musical instruments, like guitars, and respond to cryogenic treatment?

saw blades in a table saw

scraper blades

drill bits in a drill press

saw blades in a dovetail saw

metal hand files

metallic wood chisels

twin carbide blades used in power planers

carbide bits used in routers

  • Router bits come in two types, carbide-tipped and high-speed steel. High-speed steel bits are not a good investment for manufacturing applications. HSS bits are cheap, won’t hold an edge for long and do not have ball-bearing pilots, which means the operator is more likely to burn and tear wood structures used in making a guitar.
  • Prior to applying the 300 Below process, carbide bits will usually cost 3X more than high-speed steel (HSS) bits, but stay sharper by holding a better edge, usually 10 times longer.
  • 300 Below’s cryogenic treatment process will further extend this edge holding and edge taking ability, meaning carbide-tipped router bits will last even longer.

By reducing downtime in manufacturing, guitar manufacturers will save money, increase productivity, and enhance production throughput. This always helps the bottom line to keep your luthiers and production staff focused on creating great musical instrument masterpieces rather than changing out equipment in your plant operations.

Aluminum has become one of the most popular alternative materials for crafting bodies for guitar manufacturers. Its combination of high strength and low weight are attractive to guitarists around the world.

Aircraft grade aluminum (6061) is the composition of choice for guitar manufactures such as Normandy Guitars and Xtreme Guitars. It is highly machinable, weldable, and strong enough to withstand the tension created by the strings on the neck and body while maintaining a relatively low weight.

CAD and CAM systems are not limited to cutting guitar bodies alone. They are utilized by several manufacturers in cut necks, fret boards, and other parts of the guitar quickly and efficiently. The advantage of CNC machining is the accuracy and precision of the cutting.
