Hoja de sierra sable Bahco 3940-228-10-ST-5P

The Bahco 3940-228-10-ST-5P sabre saw blade is a high-speed steel (HSS) bi-metal blade designed for demanding metal cutting tasks. Each blade measures 228 mm in length, has a thickness between 0.9 mm and 1.3 mm and is suitable for cutting metal up to 1.3 mm thickness. The blade family includes heavy standard (HST) extra-thick variants and standard (ST) flexible variants; this pack contains ST blades in a retail pack of five.

Advantages

These Sandflex® bi-metal blades combine HSS toothing with 8% cobalt on a spring steel back to provide high durability and resistance to breakage. The ST version offers a standard body for increased flexibility and easier positioning in narrow or curved cuts, while the HST variant (available separately) features a wider, stiffer body for straighter cuts and greater resistance to bending and fracturing. Blades are available in a range of tooth pitches (8/12 TPI up to 18 TPI) and lengths (150–300 mm) to match different cutting speeds and finishes.

Suitable for

• Cutting thin sheet metal and light-gauge steel up to 1.3 mm
• Fast straight cuts and narrower or curved cuts where blade flexibility is needed
• General metalworking tasks requiring durable reciprocating saw blades

How to use

Fit the 3940-228-10-ST-5P blade into a compatible sabre or reciprocating saw according to the tool manufacturer’s instructions, ensuring the blade is securely locked. Select appropriate stroke speed and feed rate for thin metal (higher speed with steady, moderate feed). Maintain firm, even pressure and allow the blade to do the cutting to avoid overheating or premature wear. For curved or narrow cuts, use the ST flexible blade to follow the profile; for long straight cuts consider using an HST blade variant for improved stiffness.

Recommendations

Use cutting lubricant or coolant when making long cuts in metal to reduce heat and prolong blade life. Replace blades when teeth become dull, damaged, or when cutting performance decreases. Store blades in their original packaging to protect teeth and prevent corrosion.
