Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M36 x 1.5 is the precise tool you need for impeccable thread repairs and reinforcements. Designed to deliver clean, true internal threads that perfectly cradle Heli-Coil inserts, this bottoming tap ensures strong, vibration-resistant connections in a wide range of metalworking applications.

• Targeted for Heli-Coil inserts: Creates the exact M36 x 1.5 internal threads that allow seamless seating and optimal load distribution for wire thread inserts.
• Bottoming (STI) design: Finishes threads all the way to the bottom of blind holes, ensuring the insert sits flush and remains secure under use.
• Metric precision, specific size: Engineered specifically for the M36 x 1.5 metric standard, enabling reliable repairs in automotive, industrial, and machinery components.
• Durable HSS-G construction: Built from high-speed steel (HSS-G) for enhanced wear resistance, heat tolerance, and a longer service life in demanding tapping tasks.
• Cleaner threads, quicker repairs: Precision-ground geometry minimizes burrs and chatter, delivering ready-to-use threads that reduce rework and downtime.

This tap is ideal for technicians, machinists, and shop professionals tackling thread damage in aluminum, steel, and other common base materials. Use it to restore original strength in stripped or worn threads, enabling reliable reinsertion of standard Heli-Coil wire inserts and restoring component integrity without costly replacements.

Practical workflow tips: secure the workpiece, apply appropriate cutting fluid, and maintain steady, perpendicular alignment to the hole. Cut gradually with consistent pressure, then test the new threads with an insert to confirm proper engagement and seating. For best results, pair with compatible Heli-Coil inserts and follow your tooling system’s torque recommendations to prevent over-tapping.
