The 7 Best Hacksaw Blades of 2026

Where the Starrett box asks you to commit to ten blades, Lenox asks for the least money up front of anything in this guide and hands you two. That suits a particular shopper: one pipe to shorten, one bolt to cut, a hacksaw that lives in a kitchen drawer or behind the truck seat. The blades are 12 inches, 24 teeth per inch, and bi-metal, which is the same professional construction as our top pick in a much smaller package.

Twenty-four TPI is the middle pitch and the right one for most of what a home hacksaw meets: angle iron, rod, pipe, bolts, a fence post. We also like the shatter-resistant body. A bi-metal blade bends where a cheap carbon-steel one cracks, and that matters when you're cutting at arm's length or in a spot where you can't get your body behind the saw. They also drop straight into older frames, the kind with the cast handle and a wing nut, which is where a lot of these end up.

Eight percent cobalt is the reason to look at these. Cobalt holds its hardness at the temperatures a cut generates, which is exactly where stainless and hardened alloys punish a blade: the metal work-hardens under the tooth and an ordinary edge rounds over. GRAFF puts that cobalt in the tooth edge of a bi-metal blade, 12 inches long, 24 TPI, three to a pack, and the result is a blade that keeps shaving a chip where a plainer one starts skating.

We think of this as the pack to keep apart from your everyday blades. Rusted shelving legs, stainless bolts, a hardened shaft, the cuts that otherwise eat three cheap blades and still leave you leaning on the saw: that's the job these are for, and the higher per-blade cost stops mattering because you're spending it on the one cut that would have cost you an afternoon.

Away from stainless they're still a competent general blade, with a body that bends rather than snaps and a blue finish that makes them easy to find in a toolbox of black steel. We keep a couple in the drawer with the taps and dies and bring them out when the metal looks nasty.

Tooth count is a trade. Coarse teeth clear chips fast and eat thick sections; fine teeth put more cutting edges against thin stock so each one takes a shallow bite instead of snagging and tearing the wall. At 32 TPI an eighth-inch tube wall puts four teeth in the cut, which is what you want when a torn edge means a fitting that won't seal or a cut you have to dress before it looks finished.

The blades themselves are the usual professional sandwich: hardened high-speed-steel teeth welded to a flexible spring-steel back, 12 inches long, half an inch wide, 0.025 inch thick, with a wavy set that keeps the kerf open. The ten come in a shallow plastic case, which sounds trivial until you've had loose blades rattling around a toolbox and slicing the handle off something else.

What a fine blade asks for is patience. Let the saw do the work and you get a clean square cut with barely a burr, the kind that needs a touch of a file rather than a grinder. Lean on it and the teeth chip, which is why we treat these as tubing, sheet, and threaded-rod blades and leave the one-inch bar stock to an 18 or 24 TPI blade that clears its chips.

Most people buy the wrong pitch first, and the wrong pitch is why a hacksaw feels like hard work. Hanpex solves that by not making you choose: ten 12-inch bi-metal blades split three at 18 TPI, three at 24, and four at 32. Coarse for a post or a length of bar, middle for bolts and angle, fine for tube and sheet, and by the time the box is half gone you know which one you actually reach for.

They cut like a decent bi-metal blade should: straight, quick, and consistent from one blade to the next, with the 32 TPI leaving a finish you can live with on a cut that shows. What struck us is how little drama there was in use, no wandering off the line, no snagging at the exit, no surprises when a bolt turned out harder than it looked.

Edge holding is the part we're least sure about. Nothing in the grind or the set suggests a short life, and the fine blades have held up on tubing, but a sampler isn't the same as a pack of one pitch you've learned to trust through a season of work. Buy it to find your pitch, then buy that pitch in quantity.

Carbon fiber is not metal, and cutting it with a general-purpose blade is how you end up with a ragged edge and a part you have to replace. The fibers sit in resin, and a coarse, aggressively set tooth tears them instead of slicing them: you get fraying, a cut that isn't square, and a section that needs sanding back into shape before anything fits over it.

The CSB-1 is a 12-inch blade with a super-fine, tungsten-carbide-coated edge, built for exactly this work on handlebars, seatposts, fork steerers, and other carbon tubes. It fits Park's SAW-12 and most other 12-inch hacksaw frames, and it wants a cutting guide, light pressure, and a slow stroke. Do that and the cleanup is a pass with paper rather than a session with a file.

One blade, one material, a premium price: we're comfortable with that, because the alternative is ruining a component worth many times the blade. Cut it outdoors or behind a mask and wipe the dust up rather than blowing it around, since carbon dust is not something to breathe. This is the blade we'd reach for" — no, we reach for it when the part is expensive and the cut has to be right the first time.

Ten 12-inch bi-metal blades for barely more than the Lenox two-pack: whatever else is true about them, that's the number that sells this pack. If your hacksaw lives in a shed, a truck box, or a tack room and gets used on whatever is at hand, having ten blades you don't mind ruining changes how often you reach for the saw.

Used within their limits they're fine. Twenty-four TPI, half an inch wide, 0.025 inch thick, and they drop into any standard frame. On PVC, copper tube, aluminum, and soft steel they cut quickly and track well enough, and the wavy set clears chips without binding.

Push them and they let you know. Hard steel flattens the teeth, the edge rounds over, and the blade starts skating instead of biting. The sharpness that starts strong fades faster here than on the Lenox or Starrett blades, and now and then one gives up early rather than wearing out.

The honest use for this pack is the work where a blade is more likely to be wrecked than worn out: cutting on a ladder, in the dirt, at an angle you can't hold, on a job where you'd rather not sacrifice a good blade. Buy a box, keep it in the truck, and stop treating every cut like it costs something.
