Power hacksaw regular blades use a relatively coarse tooth pattern and a blade material that can stand up to heat and frequent cutting action. The standard choice is 6–8 teeth per inch, which provides enough cutting teeth to remove material quickly while keeping the blade strong enough to resist bending and breaking under the reciprocating action of a power saw. For the blade material, both annealed high-carbon steel and high-speed steel are common options. Annealed high-carbon steel offers good flexibility and is easy to sharpen, while high-speed steel resists heat and maintains a sharp edge longer, making it suitable for tougher cuts.

The other tooth counts aren’t aligned with a regular power hacksaw blade’s typical use: a very coarse 4 teeth per inch would gouge and struggle with chip clearance, while a finer 10–12 or 14 teeth per inch is more appropriate for finer finishes or thinner materials and not for the standard, heavier-duty regular blade.
