These 300 x 24T hacksaw blades are replacement blades for standard 300 mm (12") hacksaw frames, intended for cutting metal, plastic and other engineering materials where a fine, accurate cut is required. The designation "24T" means 24 teeth per inch (TPI), giving a fine tooth pitch optimised for cutting small-diameter tube, thin-wall sections, sheet metal and precision bar work rather than rapid stock removal.

Manufactured with a bimetal-style construction, the cutting edge is made from high-speed steel (HSS/M2 type) welded to a flexible alloy spring-steel backing. This combination gives a wear-resistant tooth hardness and a resilient body that resists snapping under tension. Blades are finished with a dark phosphate/black-oxide treatment to improve corrosion resistance and reduce friction during cutting. The blades are produced under ISO 9001 quality-controlled processes and are compatible with the dimensional conventions used for 300 mm hacksaw blades in common DIN/BS tooling systems.

These blades are used across workshops, maintenance departments and site trades. Typical industries include metal fabrication, mechanical engineering, plumbing and heating, automotive repair and general maintenance. They are suitable for manual hand-held hacksaw frames and for use in bench-mounted or portable holders where a standard 300 mm blade is required. The 24 TPI tooth form is particularly useful when cutting thin-walled tubing, conduit, bolts, studs and precision components where a smooth edge and low burr are important.

Key benefits include the combination of HSS cutting performance with the flexibility of spring-steel backing, giving long tooth life without frequent breakages. The phosphate finish offers improved corrosion resistance for storage and site use, while the 24 TPI pitch balances cutting speed with finish quality. Standard 300 mm sizing ensures wide compatibility with most hacksaw frames and holders used in the UK and European markets.
