A Large-Diameter Solution for Soft Materials
Do your customers need a large-diameter hole saw, such as 152mm?
Hongniu Tool offers the right solution. This 6 Inch Bi-Metal Hole Saw is designed for cutting soft materials such as wood and PVC.
It also performs well on plasterboard, plywood, and thin metal sheets.
This size is especially suitable for cabinet installations and ventilation openings.
Our factory, Hongniu Tool, is located in Yueqing. We believe high-quality tools come from precise manufacturing processes.

Stable Cutting Design
The saw teeth feature an alternating set design (forward and backward tilt), which improves cutting sharpness while reducing vibration during operation. This results in smoother and more stable cutting performance.
The blade is marked as HSS and BI-METAL, indicating high-speed steel bi-metal construction.
A high-temperature quenching process is applied to improve hardness and wear resistance, ensuring a longer service life.
The hexagonal shank design provides stronger grip and improved torque resistance, effectively preventing slipping during operation.
