Feature
The diameter of the hole can be adjusted according to the scale to make drilling more accurate and fast.
The carbide blade is stronger, more durable and not easy to break, making the drilling sharper and faster.
The boring diameter ranges from 1-3/16" to 4-3/4" (30mm-120mm). You can save the cost of multiple fixed-size hole saws.
It is a new tool in the decoration industry, suitable for drilling of woodworking work, laminates, plastic, acrylic, plywood, composite, plaster, rubber, and cardboard.

Warm Tips:
Not suitable for metal.
1. Before performing the operation, check whether all screws are tight.
2. Drill holes at an Angle perpendicular to the board.
3. When the drill works, the distance between the two sides must be equal, otherwise the force is uneven, affecting the drilling effect.
4. Avoid one-time perforation when drilling. It is recommended to drill for a while and then stop for a while, otherwise the blade is easy to damage.
5. Remove sawdust after drilling for a period of time. In the process of continuous drilling, the friction between the drill bit and the board causes high temperature, which is easy to cause sawdust fire.
6. The drilling cuttings produced in the drilling process should be cleaned with special tools, and can not be cleaned by hand.
7. Power off the drill before replacing it.
