70 mm Alloy hole saws are used for drilling holes in walls, stone and air conditioning systems

Premium Material: This 70mm alloy hole saw is made from a high-quality alloy offering extremely high hardness and wear resistance. Its composition allows it to maintain stable cutting performance on hard walls, stone, and other materials, thus extending its lifespan, reducing replacement frequency, and saving you money.

Widely Applicable: Designed for drilling holes in a variety of complex materials. Whether it's a thick wall requiring precise drilling for cable and pipe installation, hard stone meeting drilling needs for landscaping and building repair, or even a metal part of an air conditioning system, it is easy to handle. Its 70mm hole diameter is suitable for most common installations, such as pipes and conduits.

Efficient Drilling Performance: The unique shape and arrangement of the saw teeth significantly improve drilling efficiency.

During drilling, it cuts materials quickly, reduces jamming and resistance, and drills smooth, regular holes. Furthermore, good heat dissipation prevents overheating caused by prolonged use, thus ensuring optimal tool performance.
