МЕТЧИК, 3/8-16 Caterpillar 4C9683

The Coarse Thread Repair Tap reconditions damaged and worn internal threads by cutting new thread profiles within an existing threaded hole. It is used when threads have been distorted, stripped, and clogged, allowing restoration of the original thread path for fastener engagement. The tap operates by rotating into the hole, where its cutting edges remove irregularities and reshape the thread form to match the intended coarse pitch. During use, it guides itself along the axis of the hole while progressively reforming the internal thread geometry.Attributes:• Restores coarse thread pitch within threaded holes.• Clears debris through integrated flute channels.• Maintains alignment of internal thread geometry.Applications: The Coarse Thread Repair Tap restores damaged internal threads within threaded holes to enable proper engagement of coarse threaded fasteners during maintenance and repair operations.
