This Variable Diameter Hole Cutter covers a wide range of hole sizes with just one tool. It helps your customers save money and reduce storage space.
Our factory is located in Yueqing, Zhejiang, and we focus on producing durable cutting tools. The blades are specially ground for better cutting performance, and the high-hardness blade material provides strong drilling power and long service life.

Easy to Use on Many Materials
This Variable Diameter Hole Cutter works best on wood, plastic, and plasterboard. It can also cut plywood and aluminum sheets.
Your customers can use it with either a hand drill or a drill press. The adjustment process is simple. Turn the adjustment mechanism clockwise to increase the hole diameter, and counterclockwise to reduce it.
The adjustable cutting range is 45–130mm, and the cutting depth ranges from 3–30mm.
We have specialized in manufacturing cutting tools since 2011 and maintain strict quality control throughout production.


Simple Setup and Smart Design
To assemble the tool, insert the positioning clip into the slot first. Then align and close the cover plate. Tighten the triangular shank, followed by the hex nut. Finally, adjust and secure the blade to the required diameter.
Please make sure all parts are tightened securely before use to ensure safe operation.
The triangular shank design helps prevent slipping during drilling, making cutting safer and more accurate.
