Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BSP - 5/8 x 14 is the dedicated tapping tool you reach for when you need rock-solid, repair-ready threads in BSP applications. Built for durability and designed to pair seamlessly with BaerCoil inserts, this bottoming tap finishes the job with precision where it matters most—deep, clean threads that accept fasteners with confidence.

• Bottoming taps for true depth — engineered to thread all the way to the bottom of blind holes, ensuring a complete, engagement-ready thread every time. This is essential when a standard tap would leave shallow threads or a misfit bolt.
• G (BSP) 5/8 x 14 specification — specifically sized to the British Standard Pipe thread range, giving you reliable compatibility in plumbing, automotive, and machinery work where BSP threads are common.
• HSS-G construction for durability — built from high-speed steel G-grade tooling for longevity under demanding tapping tasks, reducing wear and extending tool life in tough materials. This aligns with Baer’s HSSG tap lineage.
• Optimized for thread-repair workflows — designed to work in harmony with BaerCoil wire thread inserts, enabling clean, repeatable repairs in both through-hole and blind-hole scenarios.
• Precise depth, minimal chatter — a purpose-built bottoming profile minimizes chattering and cross-threading risks, helping you achieve accurate thread form in tight tolerances. For context, bottoming taps finish threads after initial taper/plugs when deep engagement is required.
