Power Hacksaw Blade Selection — Quick Reference
Power hacksaw blades are the long heavy-duty hacksaw blades used in mechanical power hacksaws — reciprocating-action steel cutting machines for production cutting of bar + structural sections + tube. Slower but very accurate vs bandsaw, used where finish + dimensional accuracy matter.
| Blade Spec | Best For | TPI Guide |
|---|---|---|
| HSS All-Hard Blade | Production cutting carbon steel + light alloy | 6-14 TPI per section thickness |
| HSS Bi-Metal Blade | Mixed material + structural sections — flex-tolerant | 6-10 TPI |
| HSS Cobalt M42 Blade | Stainless + tough alloys + production volume | Same TPI range — longer life |
| Carbide-Tipped Blade | Hardened steel + high-volume production | Per spec — premium for harder substrates |
| 14 TPI (Fine) | Thin-wall tube + sheet + small section | Wall thickness ≤3mm |
| 10 TPI (Medium) | Workshop standard — most structural sections | Wall 3-12mm |
| 6 TPI (Coarse) | Thick solid bar + heavy structural | Solid stock + thick sections |
3-tooth rule: always have at least 3 teeth in contact with the workpiece at any time. Too few teeth = catastrophic blade damage; too many = chip clogging. Common dimensions: 350mm × 32mm × 1.6mm (workshop standard), 450mm + 525mm for heavier machines. Cutting fluid mandatory on power hacksaw — extends blade life 3-5×. Brands: Excision, Bordo, Sutton Tools. Companion: hand hacksaw blades, circular saw blades, cutting lubricants, cut-off discs.
