Drill bit AWTools AW43538 — metal/wood general-purpose bit, model AW43538

AWTools AW43538 is a general-purpose drill bit engineered for routine drilling tasks in workshop, construction and DIY settings. Constructed from 40CR alloy steel with a YG8C carbide-tipped blade and a centering point with a 130° angle, this bit combines durability and precise penetration. The double spiral flute design supports efficient chip removal and heat dissipation, while four cutting edges promote smooth hole finishing and reduce the chance of jamming when encountering reinforcing steel. The grooved SDS+ shank secures the bit in compatible hammer drills and rotary hammers.

Advantages

The carbide tip improves wear resistance and maintains cutting performance over repeated use. A 130° centering point provides accurate starts and reduces walking on the workpiece surface. Double-spiral flutes evacuate debris effectively, lowering temperatures and vibration during drilling. Four cutting edges deliver cleaner holes in both metal and wood and increase reliability when penetrating hard substrates. The SDS+ style grooved shank ensures stable retention in hammering tools and simplifies bit changes.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Piercing rebar and other embedded metal during demolition or installation
• Creating openings in brick and masonry
• General metal and wood drilling in workshop or construction tasks
• Use with hammer drills and rotary hammers for heavy-duty drilling

Key specifications

• Material: 40CR alloy steel body with YG8C carbide-tipped cutting edge
• Tip geometry: centering point with 130° point angle
• Flute design: double spiral for efficient chip removal and reduced overheating
• Cutting edges: four cutting edges for smooth holes and reduced jamming
• Shank type: grooved SDS+ style for secure retention in hammer drills and rotary hammers
• Intended materials: concrete, reinforced concrete, rebar, brick, metal and wood

How to use

Install the drill bit into a compatible SDS+ chuck or holder, ensuring it locks securely. Select the appropriate drill mode: rotary hammer/hammer function for concrete, reinforced concrete, masonry and rebar; rotary-only mode for metal and wood where impact is not required. Start at low speed to establish the centering point, then increase speed and apply steady, even pressure. Allow the double-spiral flutes to clear chips; periodically withdraw the bit from deep holes to remove debris and prevent overheating. Replace the bit if the carbide tip shows significant wear or chipping.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and gloves. When drilling concrete or rebar, apply controlled feed and avoid excessive force; use cooling breaks to extend tip life. Match drill speed and hammer setting to the material: higher impact for masonry and lower speed/rotary-only for metal and wood.
