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.
Who benefits most from the Baer Heli Coil Tap? professionals and shop technicians tackling threaded-in repairs on equipment, engines, and fixtures where durable, reusable threads matter. It shines in automotive restoration, industrial machinery maintenance, and any project that relies on secure, long-lasting BSP fasteners. By pairing this bottoming tap with BaerCoil inserts, you gain a repair that restores original strength and improves load-bearing performance compared with damaged or worn threads.
Why this tap stands out — it isn’t just about cutting threads; it’s about delivering consistent, reliable results that keep your projects moving. The combination of correct BSP sizing, robust HSS-G construction, and a bottoming geometry means fewer reworks, cleaner threads, and better bolt seating from the first run. When you need a trusted tool that supports durable thread repairs and reinforcements, this BaerCoil-ready bottoming tap is a precise, dependable choice.
Practical tips for best results — use the recommended cutting fluid, keep chips cleared to avoid built-up friction, and follow a tap-drill-and-tap sequence suitable for repair work (tap depth to bottom in blind holes as needed). For Helicoil-based repairs, ensure the insert and tap are matched to the correct diameter and pitch to maximize engagement and longevity.
