Drill bit Proline SDS+ 14x450 mm — for rotary hammer drilling, 14 mm diameter, 450 mm length

Proline SDS+ 14x450 mm drill bit designed for industrial and professional use. It is intended for drilling in concrete, granite and other natural stones. The bit features a specially shaped carbide insert for extended service life, high cutting efficiency and accurate, concentric drilling. A double spiral flute rapidly evacuates dust and debris. Compatible with rotary hammers that use an SDS+ shank. Size: 14 x 450 mm.

Advantages

The carbide tip shape increases durability and cutting performance while reducing load on the tool and operator. The concentric design improves hole accuracy. The double-spiral flute accelerates dust removal during drilling, maintaining drilling speed and reducing clogging. SDS+ shank ensures secure connection and easy bit changes in compatible rotary hammers.

Suitable for

• Drilling holes in reinforced and non-reinforced concrete
• Drilling in granite and other natural stone materials
• Professional construction and industrial drilling tasks
• Use with SDS+ rotary hammer drills

How to use

Install the Proline SDS+ 14x450 mm bit into the rotary hammer's SDS+ chuck until it locks. Select the rotary hammer's hammer-drilling mode and set the appropriate speed or impact setting for the material. Begin drilling with light pressure to seat the bit, then apply steady, moderate pressure—let the tool and carbide tip do the cutting. Periodically withdraw the bit to clear dust and check progress. For deep holes, withdraw more frequently to prevent clogging in the flutes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) and ensure the workpiece is supported and secured. For best results in reinforced concrete, use progressive drilling technique and inspect the bit for wear; replace the bit when the carbide tip is damaged or cutting efficiency declines.
