Bosch SDS max-9 BreakThrough Drill Bit 65 x 450 x 600 mm

The Bosch SDS max-9 BreakThrough Drill Bit 65 × 450 × 600 mm is a single-piece tungsten carbide accessory designed for heavy masonry work. This large-format bit is engineered for drilling deep through-holes in tough mineral building materials, such as solid concrete, brick, limestone, and sand-lime brick. It is used to run cables, pipes, and other structural installations through thick walls. A specialised core geometry keeps the bit stable while working deep inside abrasive substrates. The broad head design produces a wide clearance in a single pass, so no pilot drilling is needed.

The bit has an SDS Max shank, which fits directly into heavy rotary and demolition hammers. Its fluted shaft gives a long working reach, allowing the operator to pass through standard wall thicknesses without a separate extension piece. The flute geometry manages dust evacuation during continuous use, helping prevent the bit from binding as the hole deepens. A dual-tone bronze and silver finish sets the working head apart from the main body. Built for heavy industrial use, the bit handles the rotary and percussive forces involved in breakthrough drilling.

• 65 mm cutting diameter for wide clearances suited to heavy plumbing pipes and thick electrical conduits.
• 450 mm working length for continuous through-hole drilling in thick exterior walls.
• 600 mm overall length for the reach needed to bridge deep structural cavities.
• Three distinct cutting edges that break down hard aggregate efficiently and keep the bit stable at depth.
• Vacuum-brazed tungsten carbide construction that resists extreme impact and heat during continuous masonry work.
