Sabelzaagblad Bahco 3940-150-8/12-ST-5P

The Bahco 3940-150-8/12-ST-5P is a sabre saw blade for demanding metal cutting tasks. It is a bi-metal construction with HSS (high-speed steel) teeth containing 8% cobalt on a spring steel back, providing high durability and resistance when cutting sheet and thin-section metals. This ST (standard) version has a standard body and slope-shaped nose for versatile cuts and measures 150 mm in length with a thickness range up to 1.3 mm; the pack contains five blades.

Advantages

Sandflex® bi-metal construction and HSS teeth with 8% cobalt offer extended life and reduced risk of tooth breakage. The standard (ST) body provides flexibility for narrow or curved cuts while retaining sufficient rigidity for straight, aggressive cutting. Precision ground coarse teeth (8/12 TPI) ensure efficient material removal in metal and mixed materials, and the slope-shaped nose allows varied cutting angles in demanding applications.

Suitable for

• Cutting sheet metal and thin metal sections
• Straight and narrow cuts in steel and non-ferrous metals
• General workshop and on-site metal cutting tasks
• Tasks requiring occasional curved or angled cuts

How to use

Install the blade according to your sabre or jigsaw manufacturer's instructions, ensuring the teeth face the workpiece and the blade is secured in the tool clamp. Select an appropriate cutting speed and feed rate for the metal being cut; slower feed and steady motion reduce heat and extend blade life. Support the workpiece firmly and make pilot cuts or score lines for more accurate starts. Replace the blade when cutting becomes slow or the teeth show visible wear.

Recommendations

Use coolant or periodic pauses on thicker or hard metals to reduce overheating. For maximum blade life, match the TPI and blade thickness to the material thickness and the desired cut speed; use the standard (ST) blade where flexibility and maneuvering are required.
