Drill bit Bosch 2608831033 spiral cutting drill bit Ø 1.2 cm, 1 pc

Spiral cutting drill bit by Bosch with a diameter of 1.2 cm supplied as a single piece. Designed for use with drills and rotary hammers, this 12 mm bit features a spiral cutting geometry and is intended for standard drilling tasks in concrete and masonry when used with compatible SDS plus holders. Constructed from high-alloy steel with optimised hardening and fitted with indented cutting edges made from a Bosch-controlled carbide blend, the bit is engineered to offer wear resistance and accurate drilling performance. The product carries the PGM Masonry Drill Bit Association Board test mark, indicating conformity with tight tolerances and reliable fixing hold.

Advantages

The 4-flute dura design promotes effective dust removal to reduce heat development and extend tool life. High-alloy steel construction with optimised hardening enhances durability under repeated use, while carbide-blended indented cutting edges improve resistance to wear and maintain cutting precision. Compatibility with SDS plus rotary hammer holders ensures stable engagement and efficient power transfer for masonry and concrete drilling tasks.

Suitable for

• Drilling 12 mm holes in concrete
• Masonry drilling with SDS plus rotary hammers
• Installing anchors and fixings in brick or blockwork
• General construction and renovation drilling tasks requiring standard spiral cutting geometry

Key specifications

• Diameter: 1.2 cm (12 mm)
• Quantity: 1 piece
• Geometry: spiral cutting with 4-flute dura design
• Material: high-alloy steel with Bosch-controlled carbide cutting edges
• Intended materials: concrete and masonry
• Tool interface: for use with SDS plus holders (rotary hammers)

How to use

Select a compatible rotary hammer with an SDS plus chuck and secure the Bosch 12 mm spiral drill bit in the holder until it locks. Mark the drilling position, set the rotary hammer to the appropriate mode for masonry or concrete, and start drilling with steady, even pressure. Allow the bit to clear dust periodically to maintain cutting efficiency; the 4-flute design assists chip removal but intermittent withdrawal can help in deeper holes. After finishing, retract the bit while the tool is running briefly to clear remaining debris, then stop the tool and remove the bit.

Usage recommendations

Use the drill bit with appropriate personal protective equipment, including eye and hearing protection. Match drilling speed and hammer mode to the material density, and avoid excessive lateral force to prevent premature wear. For secure fixings, ensure holes meet recommended depth and diameter for the chosen anchors.
