Drill bit Bosch Breakthrough drill bit sds max-9 break through

The Bosch Breakthrough drill bit SDS Max-9 is designed for use with rotary hammers and intended for drilling large, deep holes in concrete and masonry. With a diameter of 55 mm and a length of 600 mm, this single-piece breakthrough drill bit features a long tapered shank that enables breakthrough drilling and a 2-flute U-shaped design for effective dust removal. Use with a rotary hammer of suitable capacity and follow the tool's operating instructions to avoid overload.

Advantages

The long tapered shank allows clean breakthrough-drilling while the robust single-piece construction increases durability during heavy-duty applications. The 2-flute U-shaped geometry improves dust evacuation from the hole, helping to maintain drilling speed and reduce wear on the bit. The SDS Max connection ensures secure mounting in compatible rotary hammers.

Suitable for

• Drilling large, deep holes in concrete
• Breakthrough drilling where a tapered shank is required
• Professional construction and renovation projects
• Use with SDS Max rotary hammers

How to use

Install the SDS Max-9 drill bit into a compatible rotary hammer according to the hammer's mounting instructions. Select a rotary hammer with sufficient capacity for breakthrough drilling to prevent overload. Start drilling at low speed to position the bit, then apply steady pressure and the appropriate hammer/drill settings for concrete. When breaking through, maintain control of the tool and let the tapered shank guide the bit through the material. Regularly withdraw the bit to clear dust if necessary and follow the rotary hammer manufacturer's safety and operating instructions.

Usage recommendations

Always ensure the rotary hammer used has suitable power and capacity for breakthrough drill bits to avoid motor overload. Observe the operating instructions and safety guidelines provided by the rotary hammer manufacturer.
