Bahco 321-24-SB hacksaw blade is a 31 cm metal-cutting blade engineered for precise manual sawing. With a weight of 70 g, it offers a balance between rigidity and maneuverability for controlled cuts. The blade is suitable for general-purpose cutting tasks and is compatible with standard hacksaw frames that accept blades of this length.

Advantages

The blade construction provides consistent tooth geometry for uniform cutting performance and reduced vibration during use. Its moderate weight and length make it easy to position and guide, while material selection and heat treatment improve wear resistance and edge retention. The blade delivers clean cuts with minimal burr formation across a range of metals and other materials commonly processed by a hacksaw.

How to use

Secure the blade in a suitable hacksaw frame following the frame manufacturer's instructions, ensuring the teeth face forward for cutting on the push stroke or oriented according to preferred cutting technique. Clamp the workpiece firmly, mark the cut line, and use steady, even strokes keeping the blade aligned with the intended cut. Avoid excessive bending or twisting of the blade to prevent breakage and achieve a straight cut; replace the blade when cutting becomes slow or teeth appear worn.

Recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For thicker or harder materials, consider using a blade with a finer or more suitable tooth pitch to improve cut quality and extend blade life. Store the blade in a dry place to reduce risk of corrosion and inspect teeth before each use.
