Straight Flute Tap: 7/8-18 UNS, 4 Flutes, Bottoming, High Speed Steel, Bright/Uncoated MPN:JY4848131

The Straight Flute Tap with its 5/16-18 UNC standard size can perform quick and accurate threading on a broad range of materials such as aluminum, steel, or plastics because the taper design delivers superior chip evacuation minimizing the chance of breaking tools during starts. Engineered to cut upstream, centerline or downstream each turn with a 4-flute pattern made of high-speed steel that lasts longer for durability while its bright finish offers an anti-galling protection layer and smooth cutting edges, all rolled into one versatile tool usable across the board in automotive, general manufacturing, construction, aerospace or military industries when creating external threads.
