3. Slowly guide the bit into the hole so that there is no skidding or movement
of the drill. The entire circumference of the core bit should penetrate the
drilling surface before additional pressure is applied to the handle.
4. Exert steady pressure while drilling. NEVER force the bit into the material!
5. Do not stop the flow of water or rotation of the bit while the core bit is
drilling.
6. Check the core bit if the drilling rate decreases noticeably. The slowing
penetration rate generally indicates that the bit is in need of reconditioning.

following Hand Held drilling operation instructions must be followed. Not following
