Drill bit AWTools AW43546 — model AW43546, replacement drill accessory

AWTools AW43546 is a replacement drill bit designed for general and heavy-duty drilling in hard materials. Manufactured from 40CR alloy steel with a YG8C carbide-tipped blade, the bit features a centering point with a 130° point angle and a double-spiral flute for efficient chip evacuation. The four cutting edges provide smooth hole finishes and help reduce the risk of jamming when encountering reinforcement. An SDS+ grooved shank secures the bit in compatible hammer drills and rotary hammers, making it suitable for routine maintenance and construction tasks.

Advantages

The combination of a 40CR alloy steel body and a YG8C carbide tip ensures durability and prolonged cutting performance on concrete and masonry. The 130° centering point improves drilling accuracy and reduces walking at start-up. Double spiral flutes enhance debris removal and cooling, limiting overheating and vibration during operation. Four cutting edges deliver clean holes and better penetration through rebar and reinforced concrete. The SDS+ grooved shank provides secure retention and quick bit changes in compatible tools.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Penetrating brick, masonry and block materials
• Drilling where occasional contact with rebar is possible
• Use with hammer drills and rotary hammers with SDS+ chucks
• Routine maintenance and construction drilling 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 and cooling
• Cutting edges: four cutting edges for smooth holes and reduced jamming
• Shank type: grooved SDS+ shank for secure retention
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard masonry
• Compatible tools: hammer drills and rotary hammers with SDS+ chuck

How to use

Insert the AWTools AW43546 bit into an SDS+ chuck until it locks securely. Select the hammer or rotary mode on the drill when working with concrete or masonry. Position the centering point on the marked spot and start drilling at low speed to establish the hole, then apply steady pressure and increase speed as needed. Periodically withdraw the bit to clear debris and allow cooling; use water or intermittent breaks for prolonged drilling in dense materials. Ensure the drill and bit are compatible and in good condition before operation.

Usage recommendations

Use safety equipment such as eye protection, gloves and hearing protection. For best performance in reinforced concrete, use controlled hammer action and avoid excessive lateral force. Replace the bit when carbide tip wear affects cutting efficiency or when the centering point is damaged. Store the bit in a dry place to prevent corrosion of the steel body.
