This G 1 variant has 11 threads per inch and is manufactured from HSS-Co5 cobalt-alloyed high-speed steel for dependable cutting performance and wear resistance. The straight-fluted geometry and Form B chamfer are intended for through-hole tapping, where the open hole allows chips to clear beyond the threaded section during machining.\u003c\/p\u003e\r\n\r\n\u003cdiv class=\"definition-products\"\u003e\r\n\u003cstrong\u003eWhat is a G \/ BSPP pipe thread?\u003c\/strong\u003e A G thread is a parallel or cylindrical Whitworth pipe thread specified to DIN ISO 228. It uses a 55° Whitworth thread profile and maintains a constant diameter along the threaded section, unlike tapered pipe-thread systems.
