What are saws & saw blades?
In this category you’ll find 12" hacksaw frames and replacement hacksaw blades used to cut metals, plastics, and other shop materials. Bi-metal and HSS blades deliver clean, controlled cuts and durability for everyday fabrication and maintenance work.
Which hacksaw blade TPI should I use?
- 18 TPI – Fast cuts in thick sections and softer metals.
- 24 TPI – General-purpose choice for steel tubing, angle, and profiles (common shop standard).
- 32 TPI – Thin-wall conduit, sheet, and hard materials; smoother finish, slower cut.
Tip: Keep at least 2–3 teeth engaged in the workpiece for efficient cutting and longer blade life.
Bi-metal vs. HSS hacksaw blades, what’s the difference?
- Bi-metal – Flexible spring-steel back with hardened HSS teeth. Resists breakage and fatigue; ideal for mixed-material shop work.
- HSS (High-Speed Steel) – All-HSS construction for long wear in harder materials; best where rigidity and tooth life matter most.
How do I choose a hacksaw frame?
- Blade length: Standard 12" frame accepts the most common replacement blades.
- Tension system: High-tension (often 30,000 PSI+) keeps blades straight for accurate cuts and longer life.
- Ergonomics: Comfortable grip and rigid body reduce fatigue and wandering cuts.
How do I get cleaner, longer-lasting cuts?
- Use the right TPI for the material thickness; don’t force the stroke.
- Apply steady, full-length strokes and let the teeth do the work.
- Keep blades tight and replace at the first sign of dull teeth or wandering.
- Lubricate on hard alloys to reduce heat and tooth wear.
Saws & Saw Blades FAQs
Can one blade cut both steel and aluminum?
Yes, 24 or 32 TPI bi-metal blades handle most shop steels and aluminum. For thick aluminum, a coarser 18–24 TPI can speed the cut.
Which way should the teeth face?
Teeth should point forward so they cut on the push stroke; this keeps the frame rigid and the cut straighter.
How often should I replace a hacksaw blade?
Replace when the blade glides without biting, starts to wander, or shows chipped/burnished teeth. Dull blades overheat and slow work.
Are bi-metal blades suitable for stainless?
Yes, use fine TPI (24–32) bi-metal or HSS blades, light pressure, and cutting fluid to control heat and preserve tooth edges.
