Instructions for Use

1. When drilling, keep the bit perpendicular to the processed object to avoid damaging the bit and yourself.

2. In the unlikely event of breakage, the drill bit will be considered for replacement as long as the wear mark on the helix is still visible. Timely changes will make your job easier.

3. For square sized electric or rotary hammer.
