Drill bit AWTools AW43579 — AWTools AW43579, general-purpose drill bit

AWTools AW43579 drill bit is made of 40CR alloy steel with a YG8C carbide-tipped blade and a centering point with a 130° angle. The bit features a double spiral flute and four cutting edges, and has a grooved SDS+ shank. It is designed for drilling in concrete, reinforced concrete, rebar, brick and other hard materials and is suitable for use with hammer drills and rotary hammers.

Advantages

The combination of 40CR alloy steel body and YG8C carbide tip provides durability and wear resistance for demanding drilling tasks. A 130° centering point improves bite and positioning at drill start. Double spiral flutes help evacuate debris efficiently, reducing overheating and vibrations during operation. Four cutting edges produce smooth holes and decrease the chance of jamming when encountering rebar. The grooved SDS+ shank secures the bit in compatible chucks to prevent accidental release.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Piercing masonry and brick
• Working with rebar and other hard construction materials
• Use with hammer drills and rotary hammers

Key specifications

• Material: 40CR alloy steel with YG8C carbide tip
• Point angle: 130° centering point
• Flute type: double spiral
• Cutting edges: four cutting edges
• Shank type: grooved SDS+
• Intended materials: concrete, reinforced concrete, rebar, brick and other hard materials

How to use

Secure the AWTools AW43579 into the SDS+ chuck of a compatible hammer drill or rotary hammer. Position the centering point on the marked drilling spot and start drilling at low speed to ensure correct centring, then apply steady pressure and increase power as required for the material. Periodically withdraw the bit to clear debris and allow cooling; the double spiral helps remove material during operation.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. Match drill speed and hammer function to the material being drilled and avoid excessive pressure to prolong the life of the carbide tip.
