(3)Drilling

(a)Even if you apply more-than-required pressure to the machine body, drilling can never be performed as quickly as you expect. Applying more force or pressure to the machine body than what is needed, on the contrary, damages the drill tip, resulting in the declined working efficiency and shortened life of this machine.

(b)A drill can snap sometimes when drilling is almost finished. It is important to relax your thrusting pressure when drilling is nearing the end.

HOW TO USE THE CORE BIT

When boring penetrating large hole use the core bit. At that time use with the center pin and the core bit shank provided as optional accessories.
