PENCILE RECOVERY TAP
🛠️ Pencil Recovery Tap for Core Drilling (NQ, HQ, PQ Sizes)
Reliable Tool for Core Barrel Recovery in Wireline Drilling Operations
The Pencil Recovery Tap is a specialized core drilling recovery tool designed to retrieve stuck or broken inner tubes from boreholes when standard overshot tools are unable to engage. This tool is an essential part of any professional driller’s fishing tool kit, especially in challenging mineral exploration and geotechnical drilling environments.
Description
🔧 What Is a Pencil Recovery Tap?
A pencil recovery tap (also known as a spearhead recovery tap or fishing tap) features a tapered, threaded body that securely engages with the spearhead adapter of the inner tube assembly. It is screwed directly into the stuck core barrel to allow for safe and efficient retrieval from the drill hole.
