In order to achieve the purpose, the utility model adopts the following technical scheme:

an inner bore deburring tool comprising:

hilt portion and cutting edge portion, fixed connection is on the hilt portion on the cutting edge portion, the symmetry is equipped with the cutting edge that is used for the deburring on the cutting edge portion, the cutting edge both sides are equipped with the permanent magnet that is used for collecting the sweeps that produces in the course of the work.

Preferably, the two ends of the cutting edge are provided with inclined planes, and an included angle formed by the inclined planes and the horizontal plane is 45 degrees.

Preferably, the middle part of the cutting edge is wavy, and a plurality of arc-shaped surfaces and planes are respectively arranged on the cutting edge.

Preferably, the knife edge part is provided with a dividing groove, and the dividing groove divides the knife edge part into two elastic rods.

Preferably, collecting grooves are formed in two sides of the cutting edge on the elastic rod, and the permanent magnet is fixedly connected into the collecting grooves.

Preferably, the shank portion is provided with a thread for mounting, and the thread is located at one end of the shank portion, which is far away from the blade portion.

Compared with the prior art, the utility model has the beneficial effects that:

1. during the use, the inclined plane and the drill way of user accessible cutting edge bottom openly offset, to the drill way openly deburring, accomplish the back, inwards press the elastic rod for the cutting edge is inside to move, passes the drill way with the cutting edge afterwards, makes the inclined plane at cutting edge top and drill way reverse side offset to the drill way reverse side deburring, and easy operation is convenient, has improved work efficiency.

2. The metal scraps produced when the prop is used can be collected into the collecting tank through the permanent magnet, so that the scraps are prevented from flying in a mess and polluting the working environment.
