Drill bit AWTools AW42822 — model AW42822, weight 91 g

AWTools AW42822 drill bit is engineered for reliable drilling in hard materials. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, this model AW42822 combines toughness and precision. The double spiral flute provides efficient dust and debris evacuation to reduce friction and overheating, while the grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers. Weighing 91 g, this drill bit is a compact option for masonry, concrete, granite, natural stone, brick and ceramic tile applications.

Advantages

The 40CR alloy steel body with a carbide tip offers increased wear resistance and sustained cutting performance in abrasive materials. Two cutting edges deliver balanced cutting action for cleaner holes and reduced walking at the start of drilling. The double spiral flute accelerates removal of drilled material, improving heat dissipation and extending tool life. The grooved SDS+ shank ensures a secure fit in compatible chucks and prevents accidental release during hammering action. The lightweight construction (91 g) makes it easy to handle for prolonged tasks.

Suitable for

• Drilling holes in masonry and concrete
• Working with natural stone and granite
• Installing anchors or fixing points in brick
• Cutting holes in ceramic tiles with appropriate technique
• Use with hammer drills and rotary hammers that accept SDS+ shanks

How to use

Select a hammer drill or rotary hammer that accepts SDS+ shanks and insert the AWTools AW42822 drill bit into the chuck until it locks. Use the hammer function for masonry, concrete and similar materials; for ceramic tiles, start drilling at low speed or use a guide to avoid chipping, then switch to hammer action once the tile surface is penetrated if required. Apply steady axial pressure without excessive force, allow the bit to clear dust periodically, and avoid prolonged continuous drilling to reduce overheating.

Usage recommendations

Wear appropriate eye and hearing protection when drilling. For longer service life, withdraw the bit periodically to clear debris and allow the flute to expel dust. Use lubricant or water only if recommended for the specific material and drilling method; avoid cooling fluids on carbide tips unless specified by the tool manufacturer. Ensure the SDS+ connection is clean and correctly seated before use.
