Drill bit AWTools AW43523 — metal/concrete drilling accessory, model AW43523

AWTools AW43523 is a drill bit designed for metal and concrete drilling tasks. Manufactured from 40CR alloy steel with a YG8C carbide-tipped blade, this replacement/accessory bit is intended for use in compatible chucks, hammer drills and rotary hammers. Its construction combines a centering point with a 130° point angle, a double spiral flute and a grooved SDS+ shank to deliver consistent drilling performance in concrete, reinforced concrete, rebar, brick and other hard materials.

Advantages

The carbide-tipped cutting edge improves wear resistance and maintains cutting performance over time while the 40CR steel body provides toughness. The 130° centering point supports accurate starts and reduces walking on the surface. Double spiral flutes promote efficient removal of dust and debris to lower heat buildup and vibration during drilling. Four cutting edges yield smoother holes and reduce the chance of jamming when encountering rebar. The grooved SDS+ shank secures the bit in compatible tool chucks to prevent unintentional release.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling through rebar and other embedded metal within masonry
• Drilling in brick and hard masonry materials
• Use with hammer drills and rotary hammers for on-site and workshop tasks

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped blade
• Point angle: 130° centering point
• Flute design: double spiral for chip evacuation
• Cutting geometry: four cutting edges for smoother holes
• Shank type: grooved SDS+ shank for secure retention
• Intended materials: concrete, reinforced concrete, rebar, brick, hard masonry
• Tool compatibility: hammer drills and rotary hammers

How to use

Install the AWTools AW43523 into a compatible SDS+ chuck according to the drill manufacturer’s instructions, ensuring the shank engages fully in the tool. For best results when drilling concrete and masonry, use hammer mode on appropriate power settings and apply steady, moderate pressure; avoid excessive force that can accelerate wear or cause bit breakage. Clear drilled dust periodically by withdrawing the bit or using the drill at reduced speed to allow flutes to expel debris. When drilling through reinforced concrete, proceed slowly when encountering rebar and allow the carbide tip to cut through without forcing.

Usage recommendations

Use personal protective equipment including safety glasses, gloves and hearing protection. Match drill speed and hammering force to the material hardness and the tool’s specifications. Replace the bit when cutting performance decreases or the carbide tip shows visible wear to maintain hole quality and reduce risk to the tool and operator.
