OSG 1005700408 | EXOTAP UNC 5/16" - 18 Thread Size x 0.318" Shank x 0.665" Length x 2.719" OAL Bottom (1.5P) Chamfer H3 4 Flute V Coated VC-10 10057 Straight Flute Tap

The EXOTAP-DC taps are the industry leading tap for processing threads in Cast Iron, Ductile Iron and Cast Aluminum. The combination of ultra-strong rake withVC10 powdered metal substrate makes this tap the absolute best soltion for threading ductile castings.

Features & Benefits:

• Eccentic thread relief: Reduces friction during cutting, thereby minimizing heat generation and extending life
• Straight flute design: Most rigid cut tap design, suitable for both through and blind holes
• Multi-layered TiCN (V) coating from OSG: The layered configuration resists thermal cracking while increasing surface hardness to extend life up to 3X vs monolayered TiCN
• Available DIN or ANSI oberall lengths, coolant-through or solid, metric and inch, up to 1" or M24: Absolute versatility for any machining operation in Ductile Iron
