Drill bit AWTools AW43507 — model AW43507, replacement bit for general drilling applications

AWTools AW43507 is a replacement drill bit designed for general drilling applications in construction, repair and hobby projects. Made from 40CR alloy steel with a YG8C carbide-tipped blade, this bit combines toughness and wear resistance for drilling into hard materials. The bit features a centering point with a 130° point angle, a double spiral flute for effective dust evacuation and a grooved SDS+ shank engineered to secure the bit in hammer drills and rotary hammers.

Advantages

The carbide-tipped blade and four cutting edges provide consistent cutting performance and help produce smooth, accurate holes while reducing the risk of jamming when encountering rebar. The double spiral design improves debris removal to prevent overheating and lower vibration during use. The grooved SDS+ shank ensures the bit stays securely in place under impact, making it suitable for both rotary and hammer drilling modes. Overall, the combination of materials and geometry delivers durability and stable drilling performance in hard substrates.

Suitable for

• Drilling in concrete and reinforced concrete
• Punching holes in brick and masonry
• Working with rebar and mixed hard materials
• Use with hammer drills and rotary hammers
• Repair, assembly and hobby drilling tasks

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting head
• Point angle: 130° centering tip
• Cutting geometry: four cutting edges for smooth holes
• Flute design: double spiral for efficient debris evacuation and reduced vibration
• Shank type: grooved SDS+ shank for secure retention in hammer drills and rotary hammers
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard materials

How to use

Select a compatible hammer drill or rotary hammer with an SDS+ chuck and insert the grooved SDS+ shank until it locks into place. Mark the drilling position and start drilling at low speed to establish the centering point, then increase to the recommended hammering speed for the substrate. Apply steady pressure without forcing the bit; allow the tool and carbide tip to do the work. Periodically withdraw the bit to clear accumulated dust and check for overheating. Replace the bit when cutting performance decreases or visible wear appears on the carbide tip.

Usage recommendations

Use personal protective equipment such as safety glasses, hearing protection and gloves when drilling. For prolonged drilling in reinforced concrete or dense materials, operate in short intervals to prevent overheating and prolong the life of the carbide tip. Ensure the drill is set to the appropriate hammer or rotary mode and use steady pressure; avoid excessive lateral force that can damage the bit or the tool.
