Hacksaw blade BAHCO 3809-450-38-2.00-6 — 45 cm length, 2 mm width, 38 TPI

BAHCO 3809-450-38-2.00-6 is a 45 cm hacksaw blade with a 2 mm width and a 38 TPI fine-tooth profile designed for precise metalworking and cutting thin sections. Made in Sandflex® bi-metal construction, the blade combines a hard tooth edge with a flexible backing to resist breakage and maintain cutting performance under demanding workshop or professional use. It is supplied as a replacement blade for compatible hacksaw frames and is intended for steady, accurate cutting of a wide range of materials.

Advantages

The Sandflex® bi-metal design provides enhanced resistance to shattering while delivering consistent cutting speed and accuracy. Its fine 38 TPI tooth spacing produces clean kerfs and is well suited to thin-wall metals and other thin section materials. The blade tolerates high feed pressures without breaking, improving safety and reliability compared with conventional high-speed steel blades. Proper tensioning and use will extend blade life and keep cuts straight.

Suitable for

• Precise cuts in thin metal sheets and tubes
• General metalworking and fabrication tasks requiring fine-tooth cutting
• Replacement blade for compatible hacksaw frames in workshops and professional settings

Key specifications

• Length: 45 cm
• Width: 2 mm
• Tooth pitch: 38 teeth per inch (fine tooth)
• Material: bi-metal Sandflex® construction (hard tooth edge, flexible backing)
• Weight: approximately 249 g
• Designed for high feed pressures with shatterproof performance

How to use

Fit the blade into a compatible hacksaw frame following the frame manufacturer's instructions, ensuring the teeth point in the cutting direction. Tension the blade correctly — adequate tension keeps the blade straight and reduces wear while excessive tension increases stress on the blade and frame. When cutting, select an appropriate stroke rate and feed pressure for the workpiece: harder materials typically require a lower stroke rate and higher feed pressure. Monitor chip formation and adjust feed pressure to maintain efficient cutting.

Usage recommendations

Ensure at least three teeth engage the workpiece during cutting and avoid having teeth touch the material when the machine is started. Observe chip type: fine curled chips indicate optimal feed pressure, powdery chips suggest feed is too low, and burnt chips or tooth cracks indicate excessive feed pressure. Regularly check blade tension and replace the blade if any damage or abnormal wear appears.
