DEWALT DT4340-QZ Extreme Runtime lâmina de serra circular 165 mm x 20 mm furo, 40T TCT, corte fino para madeira

Cutting clean, splinter-free lines in wood with a cordless circular saw demands a blade that stays sharp and resists binding. The DEWALT DT4340-QZ Extreme Runtime circular saw blade tackles this challenge with a 165 mm diameter, 40-tooth tungsten carbide tipped (TCT) configuration. Engineered for fine finishing in wood, it delivers smooth, precise cuts while maximizing battery runtime on cordless saws.

Who is it for

This blade is ideal for carpenters, cabinet makers, and serious DIYers who use 165 mm cordless circular saws. It excels in applications where cut quality and battery efficiency matter: trimming doors, cutting plywood, laminates, and natural timber, or producing furniture-grade edges without tear-out.

Main features

• 40-tooth TCT blade with Alternate Top Bevel (ATB) geometry for clean crosscuts and fine finishes in wood.

Tips

For best results, ensure the blade is compatible with your saw's arbor size (20 mm bore; use reducer bushings if needed). Let the blade reach full speed before engaging the workpiece and feed steadily to avoid overheating. Clean resin buildup regularly with a blade cleaner to maintain cutting performance and prolong blade life.
