Lâmina de serra sabre Bahco 3940-150-14-ST-5P aço rápido 5 unidades

The Bahco 3940-150-14-ST-5P sabre saw blade is a metal-cutting blade made from High-Speed Steel (HSS) with 8% cobalt in the tooth zone and a spring steel back. With a 150 mm overall length, 0.9 mm thickness and 14–18 TPI tooth options in the family, this ST (standard) shaped blade is designed for fast, straight metal cuts while remaining flexible enough for narrow cutting tasks. Each retail pack contains 5 blades.

Advantages

Sandflex® bi-metal construction combines an HSS tooth edge with a durable spring steel backing for high toughness and resistance to breakage. The 8% cobalt HSS teeth provide improved wear resistance and longer life when cutting metal. The standard (ST) profile with precision-ground teeth delivers fast, aggressive straight cuts and consistent performance across different metal types. Available in multiple lengths and tooth pitches, the blade family covers a wide range of metal‑cutting applications.

Suitable for

• Cutting thin sheet metal and metal panels
• General-purpose metal cutting in workshops and maintenance
• Narrow or straight cuts in steel, aluminium and other metals

How to use

Install the blade into a compatible sabre/jigsaw according to the tool manufacturer’s instructions, ensuring secure locking before use. Select an appropriate stroke speed and feed rate for the metal being cut; slower feed with steady pressure reduces tooth wear and improves cut quality. Keep the blade aligned with the cut line to avoid bending and overheating. Replace the blade when cutting performance or tooth condition deteriorates.

Recommendations

For best results on metal, use coolant or intermittent cutting to reduce heat buildup when cutting thicker or harder metals. Choose the blade length and TPI that match the material thickness and desired cut speed: coarser TPI for faster cuts in thicker sections, finer TPI for thinner sheets and cleaner edges.
