The Sealey HSB5024 Hacksaw Blade is an essential tool for professional contractors and serious hobbyists who require reliable, high-volume cutting power across various metals. Featuring a flexible bi-metal HSS (High-Speed Steel) construction, these 300mm blades offer a balanced 24tpi pitch that excels at medium-to-thin section cutting; however, users should note that the bulk 50-pack format is primarily intended for high-usage environments rather than occasional household tasks.

Yes, 300mm is the metric equivalent of the standard 12-inch hacksaw blade length.
Bi-metal construction combines the hardness of high-speed steel for cutting with a spring-steel back for flexibility and shatter resistance.
While these are designed for metal, they can cut softwoods, but the teeth will clog quickly. Use a dedicated wood saw for better efficiency.
The HSB5024 is supplied as a pack of 50 blades.
TPI stands for 'Teeth Per Inch.' A 24tpi blade has 24 teeth within every inch of the blade, making it suitable for medium-thickness materials.
Check the frame tension; if the blade is not tight enough, it will flex during the cut and deviate from the line.
Ensure you are using the correct TPI for the material thickness and avoid applying excessive downward force.
Verify that you are cutting with the teeth facing forward and ensure you are not dragging the blade on the back-stroke.
To install the HSB5024, ensure your hacksaw frame is set to the 300mm (12-inch) setting. Insert the blade with the teeth pointing forward, away from the handle. Tighten the wing nut until the blade produces a high-pitched ring when flicked; a loose blade will wander and dull quickly.
Care for your blades by keeping them dry. Exposure to humidity can lead to surface rust on the steel teeth, which compromises sharpness. Store unused blades in their original packaging to keep them organized and protected from debris.
