Speedhammer Plus Irwin Masonry and Concrete Drill Bit.

An exceptionally fast drill bit designed for impact drilling into masonry, concrete, brick, paving stones, natural stone, and granite. SDS-plus grip. Joran quality.
Speedhammer Plus drill bits are certified by the Prüfgemeinschaft Mauerbohrer e.V. (PGM). This means: limited diameter and symmetry limits, carbide tips guaranteeing precision drilling, secure anchoring and mounting, guaranteed constant quality, and safety and trust in the product.

The drill bits are equipped with 2 cutting edges (sizes 28mm and 30mm - 4 cutting edges).

Manufacturer: Irwin
Catalog number: 10501945
Diameter: 5.0 mm.
Working length: 50 mm.
Total length: 110 mm.
Application: These drills are particularly recommended for unhardened concrete, masonry, brick, paving stones, and granite. Designed for use with all SDS-plus impact drills.
Construction: Cutting angles provide strength and drilling 20% faster than other manufacturers' drills. The patented short head ensures debris is directed straight to the spiral, reducing the risk of drill blockage. Increased spiral capacity also allows for extremely fast debris removal. A self-centering tungsten carbide tip makes starting drilling easier. 25% more tungsten carbide ensures greater power and durability.
Note: When using drill bits longer than 400mm, a preliminary drilling of at least 150mm depth using a shorter bit of the same diameter is necessary.

Irwin Speedhammer Plus is the fastest concrete drill bit for impact drills, manufactured in the Danish Irwin joran factory. The high speed is achieved thanks to the innovative design - the spiral capacity with a special deep shape is increased by 28%, ensuring easy entry and exit. Meanwhile, the short tip removes dust directly to the spiral. This prevents drill bit blockages and ensures fast debris removal. The overall hardening guarantees resistance to tearing. The drill bit's spiral design and carbide tip geometry provide strength and aggressive cutting angles, as well as speeding up drilling by up to 20% compared to other competitive products. The self-centering tip eliminates slipping.
