MAKITA B-68149 SDS 4-Cutter Rotary Hammer Drill Bit 5 x 210 mm

MAKITA B-68149 SDS 4-Cutter Drill Bit 5 x 210 mm

Features: High-performance concrete drill bit Makita SDS-Plus with a 4-cutter head, specifically designed for drilling reinforced concrete. Delivers perfectly round and precise holes, reduces bit jamming when hitting rebar, and produces low vibration to extend the service life of both the bit and the rotary hammer. Ideal for high-safety installation work, such as chemical anchor fixing.
Key Features
X-Shaped Carbide Head: 4-cutter tungsten carbide evenly distributes impact forces, reducing chipping and damage when striking rebar in concrete.
Perfect Round Holes (100% Round Holes): With more cutting edges than standard drill bits, the drilled holes are exceptionally round, which is essential for installing steel and chemical anchors at their full load-bearing capacity.
Integrated Centering Tip (Precise Centering Tip): Features a sharp center point that helps start drilling exactly on target without slipping, even on smooth, hard concrete surfaces
Low Vibration Design: The 4-cutter geometry ensures smooth drilling and reduces kickback shock transmitted to the operator's hands, helping decrease fatigue during prolonged continuous work.
Application
Anchor Fixing: With perfectly round holes, steel or chemical anchor installation is secure and safe.
Structural Drilling: Ideal for drilling through beams or columns densely packed with rebar.
Materials: Reinforced concrete, brick, natural stone, and all types of masonry.
