Concrete Hammer Drill Bit Set is engineered for demanding drilling tasks in construction and renovation projects. This set from Diager, model 1004A, provides five SDS-Plus drill bits featuring 100% carbide monobloc heads and advanced geometry. The bits are designed to deliver precise, round holes in concrete, reinforced concrete, solid brick, and stone, supporting a wide range of installation and anchoring needs.
Variable number of cutters adapts to each bit diameter, ensuring optimal cutting efficiency and minimizing the risk of jamming or slippage when encountering rebar. The triple helix flute with U-shaped profile enhances dust evacuation, supporting fast drilling and maintaining hole integrity. Users benefit from reduced vibration, stable drilling, and improved bit longevity, making the set suitable for both professional and industrial applications.
The set includes bits with diameters and lengths tailored for common construction tasks: 110mm lengths for 5mm and 6mm bits, and 160mm lengths for 6mm, 8mm, and 10mm bits. The robust design ensures consistent performance, even in reinforced substrates. The prominent centering point allows for accurate hole positioning, while thick shanks and large flutes contribute to durability and efficient debris removal. These features combine to provide a reliable solution for drilling anchor holes, cable passages, and other structural penetrations in tough materials.
The carbide head is engineered as a solid monobloc, providing high wear resistance and durability. The number of cutters varies by diameter: three cutters for 5-7mm bits and six cutters for 8-20mm bits, each with an S-shaped profile for efficient material removal. Three large lateral stabilizers and a prominent centering tip ensure stability and precise starts, even on hard surfaces.
This design supports reliable drilling performance in reinforced concrete and other hard materials, reducing the risk of bit slippage or jamming. The robust head geometry maintains hole shape and supports secure anchor installations.
The triple helix flute with U-shaped cutting profile is optimized for rapid dust evacuation, which supports faster drilling and reduces bit wear. Large grooves and thick shank construction enhance debris removal and bit stability during operation.
Efficient dust removal helps maintain drilling speed and prevents overheating, contributing to longer bit life and cleaner, more accurate holes in concrete and masonry.
The Concrete Hammer Drill Bit Set ROCKFASTER DIAGER 1004A is commonly used for drilling holes for all types of fixings and cable routing in concrete, reinforced concrete, solid brick, and stone. It is compatible with SDS-Plus rotary hammers, making it suitable for construction, electrical, plumbing, and industrial installation work.
