Product DescriptionProduct IntroductionThe overall cutting head is the only one in China to have passed the PGM certification for the entire cutting head, solving the problem of small diameter fracture while possessing advantages such as high efficiency, durability, and versatility1. Efficient power transmission and drilling efficiency-Special Drill Shank Design (SDS): The tail of the SDS drill bit features a "quick clamping" design combining grooves and protrusions, which fits tightly with the collet of the electric hammer through friction. It allows for quick assembly and disassembly without the need for additional tools, saving time during replacement.-Adaptive impact function: Designed specifically for the "rotation + impact" compound action of electric hammers, the drill bit can transmit the impact force directly to the drilling surface through the hammering force of the electric hammer while rotating at high speed. It is particularly suitable for drilling hard materials such as concrete and masonry, and the drilling speed is much higher than that of ordinary Fried Dough Twists.2. High durability and long service life-High-strength material: The blade body is typically made of high-quality alloy steel (such as 42CrMo), and the blade edge undergoes special quenching treatment, resulting in high hardness and good toughness. It can withstand frequent impacts and friction, making it less prone to breaking or wearing out.-Optimize chip evacuation design: The drill bit surface features spiral chip evacuation grooves, which promptly expel debris during drilling, reducing the friction and blockage caused by debris on the drill bit, lowering the risk of overheating damage, and extending its service life.3. Wide range of applicability-Suitable for drilling various hard materials: primarily used for drilling holes in concrete, brick, stone, cement products, and other hard and brittle materials. It can also be used to create pipe holes, installation holes, etc. on walls, floors, and other basic structures.-Compatible with multiple electric hammer models: SDS-plus is one of the internationally recognized standard interfaces, compatible with most household and industrial-grade electric hammers, with strong universality, eliminating the concern of interface mismatch.4. The drilling accuracy and stability are relatively good-Accurate positioning: The drill head is usually designed with a pointed or flat cutting edge, which enables rapid positioning during drilling, reduces slipping, and ensures precise hole positioning.-High drilling verticality: The guiding effect of the spiral groove, coupled with the stable operation of the electric hammer, can reduce the deviation during drilling, especially in deep-hole operations, where good verticality can still be maintained.5. Easy to operate and highly secure-Lightweight design: Compared to traditional impact drills, SDS drills are lighter in weight, saving effort when operated by hand and reducing job fatigue.-Anti-slip and anti-drop: The groove structure at the tail engages tightly with the hammer chuck, making it less prone to loosening or falling off during high-speed impact and rotation, thereby reducing operational risks.Main ProductCompany ProfileNanjing Hawco tools company located in Wangyuan road,Jiangning Area, Nanjing, Jiangsu province, our goal is to provide customers a good balance of quality and price, and we always have high focus on quality control, punctual delivery and good service.
