Drill bit AWTools AW43604 — metal and wood drilling accessory, model AW43604

AWTools AW43604 is a versatile drill bit designed as a general-purpose drilling accessory for both metal and wood, supplied under the AWTools brand. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade and a centering point featuring a 130° point angle, this model combines durable base material with a hard cutting tip to perform in demanding workshop, construction, and maintenance tasks. The double spiral flute geometry aids efficient material evacuation, while the four cutting edges deliver smooth hole finishes and reduce the risk of jamming when encountering reinforcement.

Advantages

The AW43604 drill bit offers a carbide-tipped cutting edge for extended wear resistance and consistent cutting performance. The 130° centering point improves drilling precision and reduces wandering at startup. Double spiral flutes promote chip removal and help prevent overheating, and the four cutting edges provide cleaner holes and lower the chance of bit lock when penetrating rebar. A grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers, reducing the risk of pull-out during hammering operations.

Suitable for

• Drilling in concrete and reinforced concrete
• Working with rebar and other embedded metal elements
• Drilling into brick and masonry
• General workshop, construction and maintenance drilling tasks

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting blade
• Point angle: 130° centering point
• Flute design: double spiral for efficient chip evacuation
• Cutting geometry: four cutting edges for smooth holes and reduced jamming
• Shank type: grooved SDS+ shank for secure retention in compatible tools
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard materials

How to use

Select an appropriate drill or rotary hammer compatible with SDS+ shanks and secure the AWTools AW43604 bit in the chuck according to the tool manufacturer's instructions. For best accuracy, position the centering point on the marked drilling location and start at low speed to establish the hole, then increase speed or engage hammer action as needed for the material. Apply steady axial pressure without forcing the bit; allow the carbide tip and the double spiral flutes to remove material efficiently. Periodically withdraw the bit to clear accumulated dust and chips and to prevent overheating.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, and hearing protection) and match drilling mode (rotary or hammer) and speed to the material. Replace the bit when cutting performance declines or if the carbide tip is damaged. For prolonged tool life, avoid excessive sideways pressure and allow proper chip evacuation by withdrawing the bit periodically.
