5MM X 500MM SDS HQ Drill Bit

The TOBIT5-500SDS is a 5mm x 500mm SDS Plus HQ Drill Bit, a high-quality masonry drill bit designed for drilling accurate holes in tough materials such as concrete, brick, and stone. It features a robust Tungsten Carbide Alloy Cross Tip, known for its superior durability and resistance to wear, ensuring precise penetration through hard surfaces. The drill body is constructed from durable 40 Chrome Steel, typically hot-treated to a hardness of 45-50 H.R.C., while the carbide alloy tip achieves 88-89.5 H.R.A. The SDS Plus shank ensures broad compatibility with SDS Plus Rotary Hammer Drills and SDS Plus Shank Drills for quick and secure insertion. Its advanced 4-flute helix or double flute design facilitates rapid drill dust removal, significantly reducing friction and minimizing stress fractures within the bit for extended life. With a total length of 500mm and an effective working length of approximately 440-490mm, this bit is optimized for professional applications demanding a clean, high-performance finish. Often sand-blasted for surface treatment, and weighing approximately 0.07kg, this drill bit is engineered for reliability and heavy-duty use in construction and renovation projects.
