Power drill accessory AWTools AW16515 — accessory for electric drills, weight 496 g

AWTools AW16515 is an accessory for electric drills designed to create and repair internal threads with an M12×1.75 mm pitch. Made of HSS high-speed steel, this toolset is supplied in a storage case and includes the components needed to cut a tap-sized thread, install a spiral insert and remove the insert's tang. The complete set is intended for workshop and professional environments where engine, automotive or general metalwork thread repair is required; the product weighs 496 g and is built to be used with standard electric drills.

Advantages

The HSS high-speed steel construction delivers durability and heat resistance during tapping operations. The set contains a dedicated tap to cut the correct thread profile, an installation tool to fit the spiral insert accurately, and a breaking tool to remove the insert tip after installation. Supplied in a storage case, the kit keeps components organised and protected, improving portability and on-site usability.

Suitable for

• Repairing damaged or stripped internal threads in engine blocks and cylinder heads
• Automotive repair and maintenance tasks requiring thread restoration
• Workshop metalwork where threaded inserts are needed to reinforce or restore threads
• General-purpose use with electric drills for installing spiral inserts

Key specifications

• Includes: cutting tap, installation tool, breaking tool, storage case
• Net weight: 496 g

How to use

Secure the component to be repaired and select an appropriate pilot hole or drill size as required for M12×1.75 threads. Mount the tap or accessory in the electric drill or a suitable tapping holder, then cut the tap-sized thread using steady axial pressure and controlled rotational speed. Insert the spiral insert using the installation tool until correctly positioned, then use the breaking tool to remove the protruding tang. Clean the repaired thread and check fit with the intended fastener.

Usage recommendations

Use cutting fluid to reduce heat and improve chip evacuation when tapping. Operate the electric drill at low to moderate speeds and avoid excessive axial force to prevent tap breakage. Ensure proper alignment when inserting the spiral insert and follow standard safety practices, including eye protection and securing the workpiece.
