VIKING hand hacksaw blades are made of steel of the highest quality, which ensures a high grade of performance and durability. We recommend the Bi-metal blades because they cut nearly all types of materials. For all-round use, we recommend pitch 24 TPI. For thin wall cutting, use 32 TPI. 
If you want a faster cutting compared to usual pitch, we recommend the VIKING SUPERCUT HSS Bi-metal with variable teeth 20/24 TPI.
