Feature of product:

1. French Emperor DIAGER five-ditch and six-blade cement drill bit is a drill that can pass through steel bars. It uses a super-hard alloy bit.

2.A new type of groove strengthens the axial drilling force and enhances the seismic resistance

3.3 alloy blades, 6 main cutting edges, automatic positioning of the center point, accurate positioning, easier to crush concrete

4.The alloy cutter head has a positioning bump design, automatic positioning, circular drilling, and the position is not offset.

5.Special heat treatment, absorb shock, absorb shock wave at the same time, reduce recoil

6. Maintain simultaneous cutting in multiple directions, enhance drilling speed, and ensure stable and balanced drilling power through automatic positioning

7.Suitable for use with five-drill hammer drill

8.DIAGER is the largest manufacturer in Europe, professional manufacturer of drill bits, imported drill bits from France

Instructions for use:

1. Before drilling deep holes, pre-drill short middle length bores of the same specification to reduce the pressure on the drill.

2. It is necessary to maintain a stable pressure when drilling and to frequently remove the drill bit from the borehole to remove debris, and use a slower speed to drill harder materials to extend the life of the bit.

3. Depending on the model of the electric drill, different drilling speeds are used. In general, regardless of the size of the drill bit, the recommended speed of the electric drill is 300-400 rpm.

4. Do not use a hard hammer drill when using, just use normal force, it is not easy to cause hand fatigue.
