I got this blade for making straight cuts in mild steel with a vertical band saw. 14 TPI x 1/2" at low speed and slow material feed gave me a nice straight cut in 3/16" mild steel. I've also used this blade to cut straight through 1/8" aluminum. Using a slower steel speed and moderate material feed resulted in a good straight cut. I use an old (early 1950's) Walker-Turner Multi-Speed Band saw.
