The tangless V-COIL notch thread repair kit M 3 x 0.5 – 1.5 D gives you a reliable solution for thread reinforcement and thread repair in one compact set. Like the familiar V-COIL inserts, V-COIL notch inserts are designed for durable internal threads — but with one key advantage: the risk of losing a tang during break-off is eliminated.
The installation is built around the dedicated V-COIL notch installation tool. It features a spring-loaded blade that engages the driver notch of the insert and holds it securely. Because the notches are present on both ends of the insert, you don’t need to worry about which end is facing forward during installation.
For consistent results, the installation tools include a depth stop nut which you set to the required screw-in depth using a lock nut. The tool’s ¼" hexagon drive means you can operate it with common bit holders — by hand, with cordless screwdrivers, or even on stationary machines. Once the target depth is reached, you simply unscrew the tool. The blade automatically retracts and releases the insert.
This kit is ideal when you need to repair a damaged M3 internal thread or reinforce a new thread for improved durability. The workflow is straightforward: drill, tap, install — without tang break-off.
What does “tangless” mean on V-COIL notch inserts?
You work without a break-off tang. That means no tang removal step and no risk of losing a tang inside the component.
Do you need to watch the installation direction of the insert?
No. The driver notches are present at both ends, so you don’t need to check which end faces forward.
Can you operate the installation tool with a cordless screwdriver?
Yes. The ¼" hexagon drive lets you use standard bit holders — by hand, with cordless tools, or on stationary machines.
What is the depth stop nut used for?
It helps you set and repeat the required screw-in depth. You lock it with the lock nut to keep the setting stable.
What happens after the target depth is reached?
You simply unscrew the installation tool. The spring-loaded blade retracts automatically and releases the insert.
Can you reorder the kit components individually?
Yes. Inserts, drill, tap and the installation tool are also available separately.
