AWTOOLS AW Broca SDS-MAX 38 x 400 x 540 mm metal duro de quatro arestas para betão e alvenaria

Professional rotary hammer operators often struggle with bits that overheat, wander at the start, or clog in deep holes. The AWTOOLS AW43874 SDS-MAX bit changes that equation: a 4-cutter tungsten carbide head with self-centering tip bites instantly into concrete, reinforced concrete, masonry, brick, and natural stone, while the large-volume spiral flute evacuates dust so fast you can drill at full speed without binding. The high-grade alloy steel body resists wear, heat, and breakage, making this a go-to for demanding jobsite conditions.

Highlights

• SDS-MAX shank for maximum power transfer and secure fit in heavy rotary hammers
• 38 mm diameter, 400 mm working length, 540 mm overall length
• 4-cutter carbide head with self-centering tip for precise starts and clean holes
• Optimized large-volume spiral flute for rapid debris removal and cooler operation
• High-grade alloy steel body with tungsten carbide tip for extended service life
• Professional grade – engineered for concrete, reinforced concrete, masonry, brick, and natural stone

In daily use

Mount the AW43874 in any SDS-MAX rotary hammer and you will notice the difference immediately. The self-centering tip prevents walking on smooth concrete, so the hole starts exactly where you aim. As you drill, the four cutting edges shear material efficiently, and the spiral flute clears dust continuously, reducing friction and heat. Whether you are anchoring structural steel, setting heavy anchors, or core drilling through a foundation wall, this bit delivers fast, straight holes with less effort and fewer bit changes.
