MAKITA E-11483 SDS-Max 4-Cutter Rotary Hammer Drill Bit 28x370mm

MAKITA E-11483 SDS Max 4-Cutter Rotary Hammer Drill Bit 28x370mm

Features Makita 4-Cutter rotary hammer drill bits are a premium drilling innovation designed to meet the demands of professionals requiring maximum speed and precision. Manufactured from a special grade of alloy steel meticulously heat-treated, and equipped with a high-quality 4-cutter symmetrical tungsten carbide tip, it is noticeably more powerful and durable than conventional 2-cutter bits in both service life and heavy-duty penetration through dense concrete.
Key Features
1. 4-Cutter Technology: Delivers smooth, consistent drilling performance. The 4-cutter head prevents jamming or snagging when striking rebar in concrete, reducing the risk of carbide tip breakage.
2. High-Efficiency Dust Extraction: Engineered with an extra wide and deep flute design to quickly transport concrete dust out of the hole, reducing drill motor load and heat buildup on the bit.
3. Centering Tip: Designed with a sharp centering point for pinpoint spot marking without slipping upon start, ensuring 100% accurate hole positioning.
4. Impact Resistance: The shank structure is engineered to withstand immense impact forces from rotary hammer systems (both SDS-Plus and SDS-Max) without bending or warping easily, transferring power fully from the tool to the drill tip.
Applications
• Anchoring: Ideal for drilling holes to install steel anchors, plastic plugs, or chemical anchors because the 4-cutter head produces true-to-round holes, providing maximum anchoring grip and safety.
• Reinforced Concrete Penetration: Used for drilling walls, floors, or concrete beams in building structures requiring extra depth, especially with SDS-Max models up to 570 mm in length that can effortlessly penetrate thick walls.
• Electrical and Plumbing Work: Used for drilling holes to route electrical conduits, plumbing pipes, or ventilation ducts through brick, lightweight block, and precast concrete walls.
• Repair and demolition work: Supports heavy-duty drilling through multiple layered hard materials
