3.Monolithic alloy blade design, automatic positioning, three main cutting edges, easier to crush concrete

4.Suitable for drilling operations of various materials, eliminating the need to replace the drill tail

5.Suitable for use with a 4-hole hammer drill with no output force, no need to push forward, just press gently

6.1500 holes can be drilled for B25 concrete, 250 holes for rebar

7.World exclusive patent

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

Instructions for use:

1.It is suitable for the use of four-way hammer drill with no output force. It uses large torque to slow down the rotation speed and prevent the drill tail from overheating to extend the life of the drill. No need to push forward, just press gently.

2.Before drilling deep holes, you must pre-drill the shorter middle-length apertures of the same specification. The drill bit must be withdrawn every 10 seconds to dissipate heat.

3.Maintain a constant pressure while drilling and often remove the drill from the hole to remove debris

4. 4 kg hammer drill is recommended for drilling in cement concrete B50

5.When encountering rebar, push the drill slowly forward, do not swing up or down
