Ukuran Mata bor untuk Tap Ulir Inchi

Standar Ulir Inchi : UNC, UNF, UNEF, Whitworth, BSW, PT Pipe Tap, NPT

Dalam proses Pembuatan Ulir ukuran Inch 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 3/4, 7/8, 1″, 1 1/8, 1 1/4, 1 3/8, 1 1/2, 1 5/8, 1 3/4, 2′ kadang kita kesulitan mencari ukuran mata bor dalam ukuran Inchi juga karena satuan ukuran mata Bor yang di jual di indonesia adalah umumnya dengan satuan milimeter (mm). Perlu dilakukan konversi satuan ukuran Inchi ke milimeter.

Berikut ini adalah tabel lengkap ukuran Mata bor untuk pembuatan Ulir Inchi
