Cutting high carbon steel on horizontal bandsaw - best tpi and material of bandsaw blade?

[ELL]

At a complete guess I would go for 24 tpi and bi metal, but I am reading 14 to 18tpi. What in all of your's experience has been best for cutting high carbon steel on a horizontal bandsaw? Thanks.

It firstly depends on the thickness. Atleast 3 teeth in the metal.

HSS cobalt blades will give the best life.
The smaller bandsaws dont like low TPI blades as the bend radius is too sharp, they can still cut thick stuff with higher TPI blades but its not ideal. Low TPI blades will snap if the bends too sharp.


High carbon generally machines and cuts nicer but is it hardened? Even so, it will likely cut ok.

I guess I should have linked the page instead.. different for tube.

Band Saw Blade Teeth Per Inch (TPI) Chart

TPI is arguably the most important decision when selecting a band saw blade. Use Dakin-Flathers bandsaw teeth per inch chart for optimum performance.

I bought a blade made by them off ebay and it came with a useful A3 sized poster which takes up a large amount of my tiny shed wall. However I currently have the choice of a worn 18tpi, or a worn 18tpi, so theres not that much point in it
The blade I'd bought was a 6tpi and it lasted all of 5 minutes before the brazed joint fatigued and snaped, so while they may make good blades, I'd suggest with any brand, not to go below 14tpi on an 1140mm length.
