Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BSP - 1 x 11

The Baer Heli Coil Tap is the dedicated solution for repairing and reinforcing threads with professional-grade reliability. Built to accept wire thread inserts (HeliCoil) and paired with a true bottoming tap design, this tool delivers clean, full-depth threads in BSP configurations—so you can restore strength where it matters most, from engines and hydraulics to plumbing and machinery housings.

Why this tap stands out

Designed for durability and precision, the Baer Heli Coil Tap features a robust, purpose-built geometry that creates accurate, deep internal threads that accept helically coiled inserts with minimal tapping effort. The bottoming profile ensures the final threads reach the full depth of the intended bore, which is crucial when securing helicoil inserts or re-tapping damaged holes in BSP-threaded components.

• Full-depth bottoming geometry ensures complete thread engagement to the bottom of the hole, maximizing insert retention and load-bearing capacity.
• BSP compatibility targets a proven, widely used thread standard for plumbing, hydraulics, and fluid systems, reducing guesswork during repairs.
• Wire thread insert ready supports helicoil inserts to restore original strength and prevent future strip-out in soft or damaged materials.
• Sturdy construction built to withstand repeated use in metalworking environments, providing consistent performance over time.
• Precision control helps machinists and DIY technicians achieve tight tolerances, smooth operation, and reliable thread life in critical joints.

Whether you’re performing field repairs on equipment, refreshing worn threads on a valve body, or restoring a stripped port in a machine housing, this tap streamlines the process. It’s the tool you reach for when a standard tap alone won’t deliver the depth, accuracy, or longevity you need.

Ideal use scenarios

• Automotive and heavy-equipment maintenance where BSP threads are common and thread integrity is mission-critical. • Plumbing and hydraulic components that rely on durable, corrosion-resistant BSP connections. • Industrial machinery, gearboxes, and housings where reinforced threads prevent costly downtime. • DIY projects and shop setups that require repeatable, professional-grade thread repair outcomes.

How to get the best results

1. Prepare the hole with the correct pilot size and clean, deburred edges to ensure alignment.
2. Use appropriate cutting fluid or lightweight oil to reduce friction and extend tap life.
3. Align the bottoming tap carefully with the bore and apply steady, straight pressure to cut full-depth threads.
4. Install the Helicoil insert according to manufacturer guidelines, then break off the tang cleanly for a flush finish.
5. Inspect the repaired thread with a suitable gauge to confirm depth, pitch, and seating before assembly.

Packaged as a single, purpose-built tool, the Baer Heli Coil Tap pairs seamlessly with Helicoil inserts to deliver repeatable, professional results—every time you repair a BSP-threaded hole.

Upgrade your repair kit with the Baer Heli Coil Tap and enjoy dependable, strong threads that stand up to torque, pressure, and use over time. Your next project deserves a repair that’s engineered to last.
