FANAR UNC 5/8-11 Machine Tap DIN 376 C R40 2B HSSE 800

A precision machine tap for cutting UNC 5/8-11 threads, engineered from cobalt-alloyed HSSE steel to deliver exceptional wear resistance and heat tolerance. The 2B fit class ensures a precise, standard-compliant internal thread in a single pass, while the C-type lead chamfer (2-3 threads) balances chip evacuation and thread quality in through and blind holes.

Advantages

The HSSE 800 material with high cobalt content delivers superior hot hardness, allowing higher cutting speeds and longer tool life compared to standard HSS taps. Its straight flute design provides reliable chip flow in short-chipping materials, and the bright finish reduces friction for smoother cutting. The DIN 376 standard guarantees dimensional consistency and compatibility with common tap holders and collets.
