Drill bit AWTools AW42826, weight 164 g

The AWTools AW42826 drill bit is a rotary drilling accessory made for use with compatible hand drills, hammer drills and rotary hammers. Constructed from 40CR alloy steel with a carbide tip and two cutting edges, the bit combines wear resistance with accurate cutting. A double spiral flute evacuates material efficiently to reduce heat build-up, while the grooved SDS+ shank secures the bit in the tool to prevent accidental release during work. The bit weighs 164 g and is intended for drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles.

Advantages

The carbide tip provides improved edge retention and durability compared with standard steel tips, and the two-cutting-edge geometry delivers more precise holes with reduced chipping on brittle materials. Double spiral flutes ensure fast removal of dust and chips, helping to maintain cutting performance and lower operating temperature. The grooved SDS+ shank enables quick, secure fixing in compatible drills and rotary hammers, reducing the risk of slippage during hammering or high-torque operations.

Suitable for

• Drilling holes in masonry and concrete
• Work on granite, natural stone and brick
• Installing anchors, plugs and fixtures in tile and ceramic surfaces
• Use with hammer drills and SDS+ rotary hammers for percussion drilling

How to use

Fit the AWTools AW42826 drill bit into an SDS+ compatible drill or hammer drill chuck, ensuring the shank engages with the tool’s locking mechanism. Select the appropriate drill mode (rotary or hammer + rotary) according to the material being drilled. Start at low speed to establish the hole position, then apply steady pressure and increase speed as needed. Periodically withdraw the bit to clear accumulated dust and chips from the hole and flute to maintain performance and prevent overheating. Use appropriate personal protective equipment such as safety glasses, gloves and hearing protection.

Usage recommendations

For best results in hard or brittle materials, use percussion mode with moderate pressure and allow the carbide tip to do the cutting. Avoid excessive side load or angled drilling to prevent premature wear. When drilling deep holes, remove the bit occasionally to clear debris and allow cooling. Match drill speed and feed to the material: lower speeds for dense stone and higher speeds for softer masonry.
