Hole saw AWTools AW43312 — AW43312 model, weight 1.3 kg

AWTools AW43312 hole saw is a heavy-duty cutting accessory designed to create larger diameter round openings in masonry materials. Made of high-quality alloy steel with tungsten carbide teeth and a spiral core body, this model combines durable cutting edges with an efficient chip-evacuation design. The tool is intended for use with compatible drills and drill rigs and can be used with TCT hex or SDS core drill adapters for both rotary and impact drilling.

Advantages

The tungsten carbide teeth provide long-lasting cutting performance and resistance to wear when drilling abrasive materials such as brick, breeze block and concrete. The spiral core body reduces friction and improves dust and debris removal during operation, while discharge holes further facilitate chip extraction to keep the cutting face clear. The construction from alloy steel offers structural strength and stability under load, and compatibility with common hex and SDS adapters increases versatility across different drilling platforms.

Suitable for

• Creating round openings in brick and masonry for pipe and conduit installation
• Drilling holes in breeze block for anchor and fixings
• Making openings in concrete for light construction and retrofit tasks
• Use with compatible drill rigs and hand-held drills for professional and DIY applications

Key specifications

• Material: alloy steel body with tungsten carbide (TCT) teeth

• Chip management: discharge holes for easier chip extraction
• Compatible drilling modes: rotary and impact drilling
• Adapter compatibility: usable with TCT hex and SDS core drill adapters
• Intended materials: brick, breeze block, masonry and concrete
• Weight: 1.3 kg

How to use

Select a compatible drill or drill rig and install an appropriate TCT hex or SDS adapter if required. Mark the center of the desired opening, secure the workpiece or ensure a stable drilling position, and start drilling at low speed to create a pilot seat for the hole saw. Apply steady pressure and moderate speed for efficient cutting while allowing the spiral core and discharge holes to evacuate chips. For deeper holes, periodically withdraw the hole saw to clear debris and reduce heat build-up. Use suitable personal protective equipment, including eye protection, gloves and dust mask, and follow the drill manufacturer’s safety instructions.

Usage recommendations

For best results when working with dense masonry or reinforced concrete, use intermittent drilling to prevent overheating and ensure the tungsten carbide teeth maintain cutting efficiency. When using impact mode, confirm adapter and drill compatibility before applying impact forces. Regularly inspect the teeth and body for wear, and replace the hole saw if cutting performance diminishes significantly.
