Hammer drill bit Bosch Professional Expert SDS‑max‑8X Ø25 mm, working length 600 mm

Bosch Expert SDS Max-8X hammer drill bit designed for SDS‑max rotary hammer drills. Equipped with a full carbide, 4-cutter tip and a reinforced shank, this single 25 mm diameter drill bit is intended for heavy-duty percussion drilling in concrete and masonry. The solid carbide head resists chipping and wear to provide extended service life when working with reinforced concrete and other demanding substrates.

Advantages

The full carbide 4-cutter tip reduces jamming and maintains cutting geometry under impact, increasing drilling speed and lifetime compared with conventional bits. Reinforced shank construction improves durability during repeated hammering and prevents premature failure at the tool connection. Compatibility with SDS‑max chucks ensures secure fit and efficient energy transfer from the rotary hammer to the carbide tip. Supplied as a single piece, the bit is ready for professional use on construction and renovation tasks.

Suitable for

• Drilling holes in concrete and reinforced concrete for anchors and dowels
• Heavy-duty percussion drilling in masonry and stone
• Preparatory works in construction and renovation where durable SDS‑max bits are required

Key specifications

• Shank type: SDS‑max
• Tip material: solid carbide, 4-cutter design
• Diameter: 25 mm
• Application: percussion drilling and chiselling in concrete and masonry
• Quantity: single piece

How to use

Select a compatible SDS‑max rotary hammer and install the Bosch Expert SDS Max-8X by inserting the shank into the chuck until it locks. Use the rotary hammer in hammer or hammer-drilling mode depending on the machine and the task. Apply steady axial pressure while allowing the carbide tip to cut; avoid excessive lateral force. Withdraw periodically to clear debris and reduce heat build-up. Replace the bit when wear degrades drilling performance or the carbide tip is damaged.

Recommendations

For best results when drilling reinforced concrete, use the bit with an SDS‑max rotary hammer specified for heavy-duty applications and select appropriate drill speeds recommended by the tool manufacturer. Wear eye, ear and respiratory protection and follow site safety procedures. Store the bit in a dry place to prevent corrosion of the shank.
