Drill bit AWTools AW43566 — metal/wood drilling accessory, single-piece

AWTools AW43566 — single-piece drill bit designed for general-purpose use with standard power drills, hammer drills and rotary hammers. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade and a centering point with a 130° point angle, this bit is engineered to deliver precise starts and stable penetration in a range of materials. The double spiral flute evacuates chips and reduces heat build-up, while a grooved SDS+ style shank secures the bit in compatible chucks and prevents accidental release during operation.

Advantages

The carbide-tipped cutting edge and four cutting lips provide smooth, accurate holes and improved wear resistance compared with plain-steel bits. The double-spiral flute geometry promotes efficient removal of debris and helps lower vibration and overheating during extended drilling. A centering point with a 130° angle aids in accurate positioning and reduces walking at the start of a hole. The grooved SDS+ style shank increases retention in hammer drill and rotary hammer systems, improving safety and stability under load.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Piercing rebar and other embedded metal elements during demolition or construction
• Working with brick, masonry and other hard building materials
• General repair, installation and construction tasks requiring hammer or rotary drilling

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped blade
• Point angle: 130° centering point
• Flute type: double spiral for chip evacuation and reduced vibration
• Cutting edges: four cutting lips for smoother holes and reduced jamming
• Shank type: grooved SDS+ style shank for secure retention in compatible chucks
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard materials
• Compatible tools: hammer drills and rotary hammers

How to use

Fit the bit into a compatible chuck or SDS+ holder according to the tool manufacturer’s instructions and ensure it is locked securely. Mark the drilling position and use the centering point to start the hole at low speed, then increase speed and apply steady pressure appropriate to the workpiece and tool power. Allow the double spiral flutes to evacuate chips; periodically withdraw the bit to clear debris on deep holes. For hammer drilling in concrete or reinforced concrete, engage the hammer mode and maintain firm, controlled pressure. Always follow the drill and bit manufacturer guidelines for feed rate and speed to avoid excessive wear or overheating.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves. When drilling reinforced concrete or rebar, proceed slowly and pause to clear debris; if excessive wear or chipping appears on the carbide tip, replace the bit. Select drill speed and hammer action settings suitable for the material to maximize bit life and hole quality.
