MORESCHI’S SEGMENTAL SAW BLADES
The segmental saw blades ere used to cut ferrous and non ferrous metals, billets, tubes, profiles and bars.
The segmental saw blades are made using segments made of hardened HSS steel grade M2-1.3343 riveted on Cr-V steel blanks.
The use of segmental saw blades is economically convenient because if some teeth are broken the segment can be replaced and re-sharpened as usual.

|---|---|
| Ø D | Diametro lama / Saw blade diameter |
| B | Spessore di taglio / Kerf |
| B | Spessore del corpo / Body thickness |
| Ø d | Diametro foro centrale / Bore diameter |
| FT | Fori di trascinamento (n°x d x PCD) / Pin-holes (n°x d x PCD) |
| T | Passo dei denti / Teeth pitch |
| TV | Passo dei denti Variabile / Variable tooth pitch |
| X | Altezza del dente / Tooth height ( T x 0,45 ) |
| ab | Differenza altezza denti HZ / Tooth height difference (ab=0,20÷ 0,30 ) |
| g | Angolo di taglio / Rake angle |
| a | Angolo di spoglia / Clearance angle |
| gV | Angolo di taglio Variabile / Variable rake angle |
| G | Raggio gola dente / Gullet radius ( G = T x 0,25 ) |

The BW shape is used to cut tubes and profiles
The HZ shape is used to cut solid bars and tubes / profiles with high wall thickness
The BS shape is used to cut tubes with low or medium wall thickness.
