All Magnate bandsaw blades are welded and fabricated in the USA. The coils/material are USA brands but may not be made in the USA. All band saw blades’ pictures depict a general bandsaw blade and thus may look different from each particular item. Bi-Metal band saw blades are designed to work with a woodworking saw at a speed range of 800-3,500 fpm to cut plastics, all types of woods ( especially ideal for hard woods i.e. oak, maple, walnut or cherry), plastics, and non-ferrous metals (aluminum, copper, brass, etc). To cut ferrous metal (i.e. carbon steels, light alloy steels, mold steels, and tool steels), you must only use a metal-cutting bandsaw, at a speed range of 40 - 200 fpm. The following is a guideline for choosing an adequate tooth pattern to cut metal materials, Use * 20 - 24 variable to cut 1/16" to 1/4" thick material, * 14 - 18 variable to cut 1/8" to 3/8" thick material, * 10 - 14 variable to cut 3/16" to 7/16" thick material, * 8 - 12 variable to cut 1/4" to 1/2" thick material, * 6 - 10 variable or 6 Hook to cut 5/16" to 5/8" thick material, * 5 - 8 variable or 6 Hook to cut 3/8" to 1" thick material, * 4 - 6 variable or 6 Hook to cut 1/2" to 2" thick material, * 3 - 4 variable or 4 Hook to cut 3/4" to 4-1/2" thick material, * 3 Hook to cut 1" to 6" thick material, * 2 Hook to cut 2" to 12" thick material. Warning: For packaging purposes, this blade is folded into a coiled position which is similar to a spring and may pop open when being coiled or uncoiled. Wear heavy duty leather gloves and eye/body protection while using extreme care when coiling or uncoiling a blade. Failure to exercise the proper care could result in serious bodily injury. See your bandsaw owners manual for further safety instructions. Please refer to your owners/operation manual to make sure the blades length, width and thickness can fit your bandsaw machine.
