Buy Power Hacksaw Blades Online in Australia
Power hacksaw blades are the long, heavy-duty blades fitted to mechanical power hacksaw machines — stationary, reciprocating-action saws used in engineering workshops, steel merchants and maintenance shops to cut bar, tube, angle and structural section to length. AIMS Industrial stocks the Sutton Tools H201–H204 range of all-hard HSS power hacksaw blades, in lengths from 300mm to 450mm and pitches from 6 to 14 TPI, so you can match the blade to your machine and the section you're cutting. Our Hacksaw Blade Guide: TPI, Materials & Selection walks through the key differences if you're comparing options.
Quick Reference — Sutton Power Hacksaw Blade Range
| Model | Length | Width | TPI options | Best suited to |
|---|---|---|---|---|
| Sutton H201 | 300mm | Standard | 10, 14 | Smaller power hacksaws, thinner section and tube |
| Sutton H202 | 350mm | 25mm | 10, 14 | Light-duty machines, mixed section and tube work |
| Sutton H202 | 350mm | 32mm | 6, 10 | Standard workshop machines, solid bar and section |
| Sutton H203 | 400mm | Standard | 6, 10, 14 | Mid-size machines, widest TPI choice for mixed work |
| Sutton H204 | 450mm | 32mm | 6, 10 | Larger-frame machines, heavier structural section |
| Sutton H204 | 450mm | 38mm | 6, 10 | Heavy-duty machines, thick solid stock |
All six are all-hard, single-alloy M2 high-speed steel blades — the standard, cost-effective choice for production cutting of mild steel, alloy steel and stainless bar, flat and structural section on a power hacksaw. Confirm your machine's blade length, width and pin-centre spacing before ordering; a blade that doesn't match the frame won't tension correctly.
Choosing the right TPI (teeth per inch)
Pitch selection comes down to the wall thickness or cross-section of what you're cutting, not the overall bar diameter:
- 14 TPI (fine): thin-wall tube, pipe and sheet section, where a coarser blade would strip teeth on the thin wall.
- 10 TPI (medium): the workshop default — solid round bar, flat, angle and most structural sections in the 3–12mm wall range.
- 6 TPI (coarse): thick solid bar and heavy structural section, where a fine pitch would clog with swarf and slow the cut.
The rule that governs all of it: keep at least three teeth in contact with the workpiece at all times. Too few teeth engaged on thin material and the blade will strip or snap teeth almost immediately; too fine a pitch on thick, gummy material and the gullets clog with swarf and stop cutting efficiently. If you're cutting a mix of section sizes on one machine, the 400mm H203 gives you the widest TPI spread (6, 10 and 14) to cover more jobs with fewer blade changes.
Fitting, tensioning and running the blade
Fit the blade with teeth facing forward in the direction of the cutting stroke and tension it to the machine builder's specification — a slack blade wanders in the cut and strips teeth against the workpiece, while over-tensioning risks blade fracture. Start the cut with a few slow, light strokes to seat the teeth before increasing speed and feed, and run cutting fluid throughout the cut. Dry cutting on steel generates heat quickly that dulls or chips the teeth well before the blade's rated life is used up — see our cutting lubricants range for a fluid suited to your material.
Power hacksaw vs other cutting methods
A power hacksaw cuts more slowly than a bandsaw or cold saw, but gives a clean, accurate square cut with minimal burr — well suited to workshops doing moderate-volume bar and section cutting where dimensional accuracy matters more than raw throughput. If you're running higher volumes or need to cut a wider range of shapes and angles, a band saw blade on a horizontal bandsaw is usually the faster option. For hand-cutting single pieces on site, see our hacksaws and hand hacksaw blades — a genuinely different product to the machine blades on this page, sized and toothed for hand-stroke cutting rather than continuous machine duty.
Companion ranges
Power hacksaw blades are one part of a metal-cutting setup. Depending on your job, you may also need:
- Cutting lubricants — cutting fluid and oil to cool the blade and extend tooth life.
- Band saw blades — for higher-throughput or contour cutting on a horizontal or vertical bandsaw.
- Circular saw blades — for cold-saw and circular metal-cutting setups.
- Cut-off wheels — abrasive cutting discs for angle grinders and chop saws.
- Hacksaws and hand hacksaw blades — for hand-cutting on site or in the field.

People Also Ask — Power Hacksaw Blades
What is a power hacksaw blade?
A power hacksaw blade is a long, heavy-duty reciprocating blade fitted to a mechanical power hacksaw — a stationary machine that cuts bar, tube and structural section by driving the blade back and forth under load. They're longer, wider and thicker than hand hacksaw blades, built for continuous machine duty rather than hand-stroke cutting.
How do I choose the right TPI for a power hacksaw blade?
Match the TPI to the wall thickness of the material, not the overall bar size. Use 14 TPI for thin-wall tube and sheet, 10 TPI as the general workshop pitch for most solid bar and structural section, and 6 TPI for thick solid stock. Always keep at least three teeth in contact with the workpiece — too few teeth engaged strips them almost immediately.
What does "all-hard HSS" mean on a power hacksaw blade?
An all-hard high-speed steel blade is made from a single M2 HSS alloy through the whole blade body, rather than having a separate flexible backing. It's hard and wear-resistant, and is the standard, cost-effective choice for production cutting of mild steel, alloy steel and stainless bar and section on a power hacksaw.
What size power hacksaw blade do I need?
Power hacksaw blades are sized by length and width to suit the machine frame — AIMS stocks Sutton blades in 300mm, 350mm, 400mm and 450mm lengths with matching widths. Check your machine's blade specification or measure the old blade before ordering; a blade that doesn't match the frame's pin centres won't tension properly.
Which way should the teeth face when fitting a power hacksaw blade?
Fit the blade with the teeth pointing forward, in the direction of the cutting (push) stroke, and tension it to the machine's specification. A blade fitted backwards won't cut, and a slack blade wanders in the cut and strips teeth — check both every time you change a blade.
Is cutting fluid necessary on a power hacksaw?
Yes. Running cutting fluid cools the blade and the workpiece, lubricates the teeth and significantly extends blade life compared with dry cutting. Dry cutting on steel builds heat quickly, which dulls and chips teeth well before the blade's rated life is used up.
Why do power hacksaw blade teeth keep breaking or stripping?
The usual causes are too few teeth in contact with thin material (breaking the three-tooth rule), the wrong TPI for the section, insufficient blade tension, cutting dry, or feeding too aggressively. Match the TPI to the section, keep the blade properly tensioned, and always run cutting fluid.
Power hacksaw or bandsaw — which is better for cutting steel bar?
A power hacksaw cuts more slowly but delivers an accurate, clean, low-burr cut, which suits moderate-volume bar and section cutting where finish and dimensional accuracy matter. A bandsaw is faster and more versatile for higher-throughput or contour cutting. Both have a place in most fabrication workshops.
