Drill bit Proline SDS+ 25 x 450 mm for hammer drills, carbide tip, SDS+ shank

Proline SDS+ drill bit 25 x 450 mm for hammer drills, with a carbide tip and SDS+ shank. Designed for industrial and professional use, this drill bit is made for drilling in concrete, granite and other natural stones. Overall length 450 mm and 25 mm diameter allow deep, precise holes while the SDS+ connection ensures quick and secure mounting in compatible hammer drills.

Advantages

The special-shaped carbide insert extends tool life and maintains high drilling efficiency while improving centring accuracy and reducing load on the drill. A double spiral flute reliably removes dust and debris for continuous drilling performance. The SDS+ shank provides fast tool changes and secure retention in SDS+ chucks.

Suitable for

• Drilling anchor holes in concrete and masonry
• Installing electrical and plumbing fixtures
• Core and through drilling in natural stone (granite, etc.)
• Construction and renovation work requiring deep, precise holes

How to use

Fit the drill bit into an SDS+ compatible hammer drill until it locks. Select the hammer-drilling mode and start drilling with steady pressure, keeping the drill perpendicular to the work surface. Periodically withdraw the bit to clear dust and check progress. For very deep holes, withdraw more frequently to improve dust removal and avoid overheating.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, gloves and hearing protection). Match drill speed and hammer settings to the substrate; for harder stone use lower feed pressure and keep the bit cool by short pauses to extend tool life.
