Key specifications
Brand: Proline
Model / MPN: 5920454
EAN: 5903755920454
Type: SDS+ masonry/hammer drill bit
Diameter x length: 20 x 450 mm
Tip: carbide insert
Usage: industrial and professional
How to use
Install the drill bit into an SDS+ chuck until it locks securely. Select appropriate hammer drill settings for the material and start drilling at moderate feed pressure to allow the carbide tip to cut effectively. Withdraw periodically to clear debris if drilling deep holes and maintain steady alignment to preserve centering accuracy.

Use appropriate personal protective equipment (safety goggles, hearing protection and dust mask) and ensure the drill and bit are suitable for the workpiece.
