The double helix flute ensures rapid dust extraction and consistent drilling performance. Compatible with rotary hammers that accept an SDS+ shank.

Advantages

The specially formed carbide insert provides extended durability and high cutting efficiency while maintaining precise, concentric drilling. The double-spiral flute design accelerates dust removal to keep the hole clean and reduce friction. SDS+ shank enables quick, secure mounting in compatible hammer drills.

How to use

Install the Proline SDS+ bit into a compatible hammer drill with an SDS+ chuck following the tool manufacturer's instructions.

Use appropriate safety equipment, including eye protection and dust mask.

Usage recommendations

For best results when drilling in reinforced concrete or very hard stone, use a rotary hammer with sufficient impact energy and allow the bit to cool between long drilling intervals to prolong service life.
