Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In addition, the hole saw mentioned in the embodiments of the present invention refers to a shaft made of carbon steel and matched with the centering drill, which can cut very hard materials, including hardened steel, cast iron, bricks, etc.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-2, a hole saw guide, comprising a clamping mechanism and a wood guide block 6, the wood guide block 6 is arranged on the upper surface of the thin plate 7 to be processed, the wood guide block 6 is provided with a cutter guide hole 10, the hole saw 4 is arranged in the cutter guide hole 10, the clamp mechanism clamps the wood guide block 6 and the thin plate 7 to be processed, the clamp mechanism comprises C-shaped clamp bodies 5 which are arranged in pairs, the two C-shaped clamp bodies 5 are arranged oppositely, a screw rod 2 is arranged at the top of each C-shaped clamp body 5 in a penetrating mode, the upper end of the screw rod 2 is connected with a handle 1, the middle of the screw rod is in threaded connection with the top of the C-shaped clamp body 5, a pressing block 3 is fixedly arranged at the lower end of the screw rod, a wooden guide block 6 and a thin plate 7 to be processed extend into the C-shaped clamp body 5, and the wooden guide block and the thin plate are clamped between the pressing block 3 and the lower end of the C-shaped clamp body 5.
