Drill bit AWTools AW43725 — model AW43725, weight 760 g

AWTools AW43725 drill bit model AW43725 is a single heavy-duty bit weighing 760 g, intended for use with compatible hammer drills and rotary hammers. Constructed from high-quality alloy steel with a tungsten carbide tip, the bit combines a wide flute and two-cutting edges for efficient material removal. The 130° self-centering point enables accurate starts without a separate pilot hole, while the double spiral geometry promotes chip evacuation, lowers vibration and helps prevent overheating. The grooved SDS-MAX shank secures the bit in the chuck and reduces the risk of accidental release during use. The bit is designed for drilling in masonry, concrete, granite, natural stone, brick and ceramic tiles; suitability depends on drill model and chuck compatibility.

Advantages

The AWTools AW43725 offers a tungsten carbide tip for extended wear resistance and sustained cutting performance in abrasive materials. Its alloy steel body with a wide flute and double spiral delivers consistent chip removal and reduced friction, which contributes to lower operating temperatures and steadier drilling. The 130° self-centering point improves start accuracy and reduces the need for pilot holes, while the grooved SDS-MAX shank provides reliable retention in compatible hammer drills and rotary hammers. The overall design balances durability and usability for demanding drilling tasks in hard building materials.

Suitable for

• Drilling holes in concrete for anchors and through-fixings
• Creating openings in masonry, brick and natural stone
• Installing fixtures in granite and ceramic tile with appropriate technique
• Use with hammer drills and rotary hammers that accept SDS-MAX shanks

How to use

Select a hammer drill or rotary hammer that accepts SDS-MAX shanks and ensure the tool is in good working condition. Insert the AWTools AW43725 bit into the chuck until it locks with the grooved SDS-MAX connection. For hard materials such as granite or dense concrete, start at low speed to establish alignment using the 130° self-centering point, then apply steady pressure and increase speed as appropriate for the drill and material. Use the hammer function when drilling masonry, concrete or brick; switch to rotary mode where impact is not required, for example when finishing in ceramic tile with careful technique. Maintain straight alignment and avoid excessive side load to protect the cutting edges and shank. Allow the bit to cool periodically during extended drilling to reduce wear.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask. Match drill speed and hammer function to the material being drilled, and secure the workpiece before drilling. For through-holes in tiles or fragile finishes, consider masking and start with reduced speed to prevent chipping. Inspect the tungsten carbide tip regularly and replace the bit when cutting performance declines.
