Taparia All Hard Hacksaw Blade HBHC1218 is a 12-inch carbon steel blade at 18 teeth per inch — the general-purpose blade for mild steel, brass, aluminium and plastic.

TPI is the specification that decides whether a hacksaw cuts or skips, and the rule behind it is simple: at least three teeth should be in contact with the material at all times. Too few teeth engaged and the blade catches, jumps out of the cut, and strips its own teeth. At 18 TPI this suits medium-section solid material — rod, flat bar, angle, and pipe with a reasonable wall thickness.

All hard means the entire blade is hardened, not just the teeth. That gives a straighter, more accurate cut because the blade resists flexing, and it holds an edge longer. The trade-off is that an all-hard blade is brittle: bend it and it snaps rather than deforming. Keep the cut straight and let the blade do the work.

Technical Specifications

1) What does 18 TPI mean, and is it right for my job?

Teeth per inch. 18 TPI is the general-purpose choice for mild steel rod, flat bar, angle and reasonable-wall pipe. For thin sheet or thin-wall tube, use a finer blade (24 or 32 TPI) or the teeth will catch and strip.

2) What does “all hard” mean?

The whole blade is hardened, not just the teeth. It cuts straighter because it resists flexing, and holds its edge longer. The trade-off is brittleness — it snaps rather than bends.

3) Which way round does the blade go?

Teeth pointing forward, away from the handle. A hacksaw cuts on the push stroke. Fitted backwards it will barely cut at all, which is a surprisingly common mistake.

4) Why do my blades keep breaking?

Usually insufficient tension, a twisted frame, or too much pressure. A slack blade wanders and binds in the cut. Tension it properly, keep the frame straight, and let the blade cut rather than forcing it.

5) Will it cut stainless or hardened steel?

Carbon steel blades struggle with stainless and will not touch hardened steel. For those, use a bi-metal or HSS blade rated for the material.
