Drill bit AWTools AW42827, 211 g weight

The AWTools AW42827 drill bit is a precision drilling accessory designed for masonry and stone applications. Made from 40Cr alloy steel with a carbide tip and two cutting edges, this bit combines durability and sharpness for consistent hole-making. Its double spiral flute accelerates chip removal and helps reduce heat buildup, while the grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers. Weighing 211 g, the AW42827 is a practical option for professional and DIY tasks that require reliable performance in hard materials.

Advantages

The combination of 40Cr alloy steel and a carbide tip provides a balance of toughness and cutting hardness for prolonged life in abrasive materials. Two cutting edges ensure stable drilling and accurate hole geometry, while the double spiral flute improves debris evacuation to maintain cutting efficiency. The grooved SDS+ shank enables fast installation and reduces the risk of accidental release during hammering. Overall, the bit is engineered to resist overheating and wear during repeated use in masonry and stone.

Suitable for

• Drilling holes in masonry, concrete and brick
• Working with granite and natural stone
• Cutting through ceramic tiles with appropriate drill technique
• Use in hammer drills and rotary hammers with SDS+ holders

Key specifications

• Material: 40Cr alloy steel with carbide tip
• Cutting design: two cutting edges
• Flute: double spiral for efficient debris removal
• Shank type: grooved SDS+ for secure mounting
• Intended materials: masonry, concrete, granite, natural stone, brick, ceramic tiles
• Weight: 211 g

How to use

Select a compatible hammer drill or rotary hammer with an SDS+ chuck and insert the grooved shank until it locks. Start drilling at low speed to establish a pilot position, then apply steady pressure and use the hammer function for hard materials such as concrete or granite. Periodically withdraw the bit to clear accumulated debris and allow cooling; the double spiral flute assists in chip evacuation. For ceramic tiles, begin with reduced impact or drill without hammer action until the glaze is penetrated to avoid cracking.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection and a dust mask. Use water cooling sparingly only when compatible with the tool and workpiece, and avoid excessive side load to preserve the carbide tip. Replace the bit when cutting performance declines or if the tip is visibly damaged.
