Drill bit AWTools AW43531 — HSS/Carbide unknown length and diameter

AWTools AW43531 drill bit is a carbide-tipped masonry bit designed for drilling in concrete, reinforced concrete, rebar, brick and other hard materials. The body is made of 40Cr alloy steel with a YG8C carbide tip and features a centering point with a 130° point angle. A double-spiral flute ensures effective removal of debris while reducing heat build-up and vibration; four cutting edges produce smooth, accurate holes. The SDS+ grooved shank secures the bit in compatible hammer drills and rotary hammers. Specific diameter and length are not specified; the AW43531 is intended as a replacement or matching bit where AWTools specifications are required.

Advantages

The combination of 40Cr alloy steel body and YG8C carbide tip provides improved wear resistance and blade durability for demanding masonry work. The 130° centering point facilitates precise positioning and reduced walking at the drill start. Double-spiral geometry speeds up dust and chip evacuation to help prevent overheating, while the four cutting edges reduce the risk of jamming when encountering reinforcement. The SDS+ shank design ensures reliable retention in hammer drill chucks and allows quick bit changes.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Percussion drilling in brick and masonry
• Drilling through rebar and hard mineral aggregates
• Use with hammer drills and rotary hammers that accept SDS+ shanks

Key specifications

• Material: 40Cr alloy steel body with YG8C carbide tipped blade
• Tip design: centering point with 130° point angle
• Flute: double-spiral for effective chip removal
• Cutting edges: four cutting edges for smooth holes
• Shank type: grooved SDS+ for secure retention
• Application: designed for concrete, reinforced concrete, rebar, brick and other hard materials

How to use

Fit the AWTools AW43531 drill bit into an SDS+ compatible hammer drill or rotary hammer and ensure the shank locks securely. Select the appropriate drilling mode (hammer or rotary) for the material. Position the centering point on the marked spot and start drilling at low speed to establish the hole, then increase speed and hammer action as needed. Apply steady axial pressure without forcing the bit; allow the carbide tip and double-spiral flute to evacuate debris. Periodically withdraw the bit to clear dust and prevent clogging during prolonged drilling.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and, when drilling reinforced concrete, proceed cautiously to avoid sudden contact with rebar. Match drilling speed and hammer power to material hardness and let the bit cool between extended runs to preserve the carbide tip life.
