Drill bit AWTools AW43603 — AWTools AW43603, general-purpose metal/wood drilling bit

AWTools AW43603 drill bit is a single replacement bit designed for general-purpose drilling in a wide range of materials. Constructed from 40Cr alloy steel with a YG8C carbide-tipped blade, the bit features a centering point with a 130° point angle and a four-edge cutting geometry. A double spiral flute ensures reliable chip removal and reduced vibration, while the grooved SDS+ shank secures the bit in hammer drills and rotary hammers. This bit is intended for routine repair, assembly and construction drilling where a versatile, durable tool is required.

Advantages

The carbide-tipped cutting edge provides increased wear resistance and consistent cutting performance over prolonged use. The 130° centering point improves accuracy at drill startup and reduces walking on the surface. Double spiral flutes evacuate debris efficiently to limit overheating and maintain cutting speed, while the four cutting edges produce smooth, clean holes and reduce the chance of jamming when encountering rebar or hard inclusions. The SDS+ grooved shank offers secure retention in compatible hammer drills and rotary hammers, enabling both rotary and hammer drilling modes.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Punching through rebar and other embedded metal with reinforced drilling techniques
• Creating openings in brick and masonry
• General-purpose repair and assembly work in construction and renovation

Key specifications

• Material: 40Cr alloy steel body with YG8C carbide-tipped blade
• Point angle: 130° centering point for improved start accuracy
• Cutting geometry: four cutting edges for smooth hole finishes
• Flute design: double spiral for efficient chip evacuation and reduced vibration
• Shank type: grooved SDS+ shank for secure retention in compatible drills
• Suitable drill types: hammer drills and rotary hammers (rotary/hammer modes)
• Recommended use: concrete, reinforced concrete, rebar, brick and other hard materials

How to use

Select the appropriate drill speed and mode for the material: use hammer mode for concrete and reinforced concrete, and rotary mode for softer masonry or when precision is required. Insert the grooved SDS+ shank fully into the chuck until it locks. Position the centering point at the desired mark and start drilling at low speed to establish a precise entry, then increase speed while maintaining steady pressure. Periodically withdraw the bit to clear accumulated debris and allow cooling. When drilling into rebar or dense inclusions, maintain steady force and avoid lateral bending to protect the carbide tip.

Usage recommendations

Wear appropriate personal protective equipment (eye protection, hearing protection and dust mask) and secure the workpiece before drilling. Use lubricant or intermittent operation only where recommended for specific materials; for masonry and concrete, avoid liquid coolants. Inspect the bit before use for damage or excessive wear and replace when cutting performance degrades to avoid poor hole quality or breakage.
