VCOIL Plug Gauge (D/E) - UNF (STI) - Heli Coil Gauge - Right Hand - 3B - No. 10 x 32 Endmill25 which helps produce excellent finishes

which helps produce excellent finishes at high speeds

Variable index 4-flute design with dual helix angles: Flutes with 29° and 31° helix angles minimize chatter and vibration

Coating: TiAlN coating reduces friction and heat build-up

and improves overall hole quality across materials

VCOIL Plug Gauge (D/E) - UNF (STI) - Heli Coil Gauge - Right Hand - 3B - No. 10 x 32 Endmill25 which helps produce excellent finishesThe VCOIL Plug Gauge (D E) is a precision UNF right hand go no go gauge designed to verify No. 10 x 32 threads to ANSI ASME standards. Built for reliable QA in manufacturing and maintenance, it provides quick, repeatable checks with a clear pass fail result. Go No Go design: Combines a go end (hand screws into the thread) and a no go scrap end (limits how far the scrap side can be turned into the cut thread). Thread type: UNF (Unified Fine) right hand
