DeWALT DT2443L-QZ jigsaw/scroll saw/reciprocating saw blade 2 pc(s)

DeWALT DT2443L-QZ jigsaw/scroll saw/reciprocating saw blade, 2 pieces per pack, is a bi-metal cutting blade engineered for demanding cutting tasks. The blade combines a high carbon steel body with high speed steel teeth for improved toughness and wear resistance. An optimized tooth geometry ensures faster, more effective cutting, while the ToughCoat heat-resistant coating reduces heat build-up to extend blade life. Increased cobalt content in the tooth material further enhances durability for repetitive or heavy-duty use.

Advantages

The bi-metal construction delivers a balance of flexibility and hardness: a resilient HCS body resists breakage and the HSS teeth maintain a sharp edge longer. Optimized tooth geometry improves cutting speed and efficiency, reducing cutting time on wood and mixed materials. ToughCoat ceramic-style heat-resistant coating reduces friction and overheating, helping preserve temper and hardness in the cutting edge for extended service life. Higher cobalt content in the tooth alloy increases wear resistance when cutting abrasive materials.

Suitable for (tasks / use cases)

• Straight and curved cuts in wood and soft metals
• Demolition and renovation work with reciprocating saws
• Precision jigsaw or scroll saw operations requiring long blade life
• Cutting mixed materials where a durable tooth edge is needed

Key specifications

• Construction: Bi-metal (HCS body with HSS teeth)
• Coating: ToughCoat heat-resistant finish to reduce heat build-up
• Tooth design: Optimized geometry for faster, effective cutting
• Tooth material enhancement: Increased cobalt content for improved wear resistance
• Pack quantity: 2 blades per pack

How to use

Install the blade into the compatible jigsaw, scroll saw or reciprocating saw according to the tool manufacturer's instructions, ensuring secure locking before operation. Select an appropriate cutting speed and feed rate for the material: slower feed for metals and steady progressive feed for wood to avoid overheating. Allow the blade to perform the cutting action without applying excessive lateral force; use steady, even pressure and let the blade's geometry and hardness do the work. Replace blades once cutting performance declines or if teeth are visibly worn or damaged.

Usage recommendations

For best results, match the blade length and tooth pitch to the material and saw type, maintain a moderate cutting speed on metals, and clear chips frequently to avoid clogging. Store blades dry and protected from corrosive environments to preserve the ToughCoat finish and extend service life.
