Drill bit AWTools AW43591 — metal and wood drill bit, spiral design

AWTools AW43591 — metal and wood drill bit, spiral design is a replacement drilling tool intended for general drilling tasks in a range of common and hard materials. Constructed from 40Cr alloy steel with a YG8C carbide-tipped blade, the bit features a centering point with a 130° angle and a double spiral flute that improves chip evacuation. The design includes four cutting edges for smooth hole finishes and a grooved SDS+ shank to secure the bit in compatible chucks. The geometry and materials make this bit suitable for use with handheld drills, bench drills, hammer drills and rotary hammers when working with wood, metal, concrete and masonry.

Advantages

The carbide-tipped cutting edge provides enhanced wear resistance and maintains sharpness when drilling abrasive or hard substrates. The double spiral flute accelerates removal of chips and dust, reducing heat buildup and vibration during continuous operation. A 130° centering point improves accuracy at drill start and reduces walking on smooth surfaces. Four cutting edges contribute to cleaner, more precise holes and lower the likelihood of jamming when encountering reinforcement. The grooved SDS+ shank ensures secure retention in compatible rotary hammers and hammer drills, minimizing slippage under impact.

Suitable for

• Drilling in wood and metal for repairs and fabrication
• Drilling in concrete, reinforced concrete and rebar with rotary hammer or hammer drill
• Masonry work including brick and block drilling
• Workshop maintenance, construction site tasks and DIY projects

Key specifications

• Material body: 40Cr alloy steel
• Cutting tip: YG8C carbide-tipped blade
• Point angle: 130° centering point
• Flute design: double spiral for efficient chip evacuation
• Cutting edges: four cutting edges for smoother holes
• Shank type: grooved SDS+ shank for secure retention
• Suitable tool types: handheld drills, bench drills, hammer drills, rotary hammers

How to use

Install the AWTools AW43591 into a compatible chuck or SDS+ holder and ensure it is fully seated and locked before operation. Select an appropriate rotational speed and hammer setting for the material being drilled; lower speeds and intermittent pressure are recommended for harder substrates. Begin drilling with steady, moderate pressure to allow the centering point to engage and prevent walking. Withdraw periodically when drilling deep holes to clear chips and allow the tip to cool, and replace the bit if the cutting performance deteriorates.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves. Match drilling speed and hammer action to the material: use rotary hammer hammer mode for reinforced concrete and rebar, and use rotary-only mode or a standard drill for wood and metal. Avoid excessive lateral force that can damage the carbide tip, and allow the bit to cool between heavy-duty uses to prolong service life.
