Drill bit AWTools AW43594 — metal/concrete drilling accessory

AWTools AW43594 — metal/concrete drilling accessory is a single replacement drill bit designed for use with electric drills, hammer drills and rotary hammers. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade, this bit features a centering point with a 130° point angle and a double spiral flute for efficient material removal. The grooved SDS+ shank ensures secure mounting in compatible chucks, while four cutting edges provide smooth hole finishes and reduce the risk of jamming when encountering rebar.

Advantages

The combination of a durable 40CR body and a YG8C carbide tip offers wear resistance and long service life when drilling hard materials. The 130° centering point improves accuracy at the start of drilling, and the double spiral design promotes rapid evacuation of dust and chips to protect the tool from overheating and minimize vibration. Four cutting edges maintain steady progress through concrete and reinforced concrete and help produce clean, round holes with lower tendency to bind.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Drilling into brick and masonry
• Punching through rebar and other embedded metal elements
• Use with hammer drills and rotary hammers with SDS+ chuck
• Replacement bit for professional construction and DIY repair tasks

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting head
• Tip: Centering point with 130° point angle
• Flute design: Double spiral for efficient chip removal
• Cutting geometry: Four cutting edges for smoother holes and reduced jamming
• Shank type: Grooved SDS+ for secure retention in compatible chucks
• Intended materials: Concrete, reinforced concrete, rebar, brick and similar hard building materials
• Tool compatibility: Hammer drills and rotary hammers with SDS+ fittings

How to use

Mount the AWTools AW43594 drill bit into an SDS+ compatible chuck according to the drill manufacturer's instructions until it locks securely. Select the hammer or rotary drilling mode suitable for the material and set the appropriate rotational speed. Begin drilling with light pressure to establish the centering point, then apply steady, controlled force while allowing the double spiral flutes to evacuate debris. If encountering reinforcement bars, proceed cautiously and maintain control to avoid sudden binding. Withdraw the bit periodically to clear dust and chips for more efficient cutting and reduced heating.

Usage recommendations

Use eye and ear protection and a dust mask when drilling. For extended drilling sessions in dense concrete, use intermittent breaks to allow the bit to cool and consider using water or a dust extraction system where appropriate. Verify that the chosen drill and chuck are compatible with SDS+ shanks and match drill speed and hammer action to the material to achieve the best performance and bit life.
