Pilot drill for hollow hammer core drill bit VARIANT

This centering drill is one of the 3 components necessary for assembling a complete core drill bit for VARIANT concrete.

Ensures accurate guidance of the crown into the material

What to combine with:

• To assemble a complete VARIANT core drill, 3 components are required - the VARIANT crown (order no. 2002), the VARIANT chuck (order no. 2008) and this centering drill. If necessary, the set can be supplemented with a VARIANT extension.

Pay attention to the correct procedure for mounting the drill assembly:

• Before mounting, clean the threads on the individual components of the assembly and, if necessary, with a thin layer of VARIANT grease
• Screw in the centering drill as far as it will go into the VARIANT clamp (or into the VARIANT extension).
• Tighten thoroughly
• Only then screw on the VARIANT crown.
• Be careful that the crown and counterpart do not act as a lock nut on the centering drill.

Do not confuse with the VARIANT centering drill designed for VARIANT stars.
