Drill Bit AWTools AW43517 — solid metal twist drill for general use

AWTools AW43517 — solid metal twist drill for general use is a multi-material drill bit designed for drilling in concrete, reinforced concrete, rebar, brick and other hard materials. The bit combines a 40CR alloy steel body with a YG8C carbide tipped blade and a centering point with a 130° point angle. Its double spiral flute and four cutting edges improve chip evacuation and hole quality, while the grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers.

Advantages

The combination of a 40CR alloy steel body and a YG8C carbide tip provides wear resistance and impact strength for drilling into hard substrates. The 130° centering point facilitates accurate starts and reduces walking on the surface. Double spiral flutes expel dust and debris efficiently, helping to prevent overheating and reduce vibration. Four cutting edges produce smoother holes and lower the chance of the bit jamming when encountering rebar. The grooved SDS+ shank ensures stable retention in hammer drill chucks designed for SDS+ accessories.

Suitable for

• Drilling holes in reinforced concrete and concrete structures
• Drilling into brick and masonry
• Working with rebar where four cutting edges reduce jamming
• Use with hammer drills and rotary hammers that accept SDS+ shanks
• Workshop, construction site, and DIY repair tasks

How to use

Mount the AWTools AW43517 drill bit securely into an SDS+ compatible chuck according to the drill or rotary hammer manufacturer's instructions. Select the hammering mode when drilling into concrete or reinforced materials; use rotary-only mode for non-hammerable substrates if applicable. Start drilling at low speed to establish the centering point, then increase pressure and speed as appropriate while maintaining firm, even feed. Periodically withdraw the bit to clear accumulated dust and debris and to allow cooling; use water cooling only if the drill and workpiece allow it and the manufacturer permits.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Match drill diameter and type to the anchoring or fixing system. Avoid excessive axial force or lateral bending to prolong tip life; replace the bit if the carbide tip becomes chipped or worn to maintain drilling accuracy and safety.
