Bosch PRO SDS max-9 Break Through Drill Bit 55 x 850 x 1000 mm

The Bosch PRO SDS max-9 Break Through Drill Bit 55 x 850 x 1000 mm is a single SDS Max break-through drill bit for producing large through-holes. Its tungsten-carbide construction is intended for sustained cutting contact with dense mineral substrates. The bit is specified for concrete and masonry drilling with a suitable rotary hammer. This format addresses deep penetrations and openings for through-installation work rather than a range of smaller hole sizes. The stated applications cover professional construction, renovation, and installation work requiring a long, large-bore bit.

The tapered shank is designed for rotary hammers fitted with an SDS Max chuck. Its extended form provides the reach needed to pass through substantial masonry sections. A dedicated diameter keeps the bit focused on one opening size instead of general-purpose drilling. The cutting head uses multiple edges to work across the full bore during hammer drilling. This configuration is intended for large, deep bores where both diameter and reach are fixed job requirements.

• 55 mm working diameter for large through-holes.
• 850 mm working length supports deep drilling tasks.
• 1,000 mm overall length provides extended reach.
• Three cutting edges form the tungsten-carbide tip.
• Rated for brick, concrete, concrete building blocks, limestone, and lime-and-sand brick.
• Bronze and silver colour finish.
