Value Collection 78119 Thread Mill 11/16-16 Unf Internal Solid Carbide

Product Description

The VALUE COLLECTION 78119 is a straight flute thread mill designed for cutting internal UNF threads at an 11/16-16 specification. Built from solid carbide grade K27C, this tool delivers consistent thread form and dimensional accuracy in demanding machining environments. It features 5 flutes with a bright, uncoated finish and a cutting diameter of 0.47 inches. With a shank diameter of 0.5 inches and an overall length of 3.27 inches, it fits standard CNC milling setups. Machinists and tool and die professionals use this thread mill when tapping is not practical or when thread quality requirements are high.

This thread mill is suited for internal thread milling operations on CNC machining centers where helical interpolation is available. At 16 teeth per inch, it produces clean UNF thread forms in a single helical pass. The 1.125 inch length of cut accommodates typical thread depth requirements for 11/16-16 UNF applications in ferrous and non-ferrous materials. Coolant-through capability is not present on this tool, so external flood or mist coolant is recommended to manage chip evacuation and tool temperature during the cut.

Key Features

• Solid carbide K27C construction for rigidity and wear resistance in thread milling applications
• 5 straight flutes with bright uncoated finish for reduced coating buildup in lighter-duty materials
• 16 TPI cutting geometry matched to 11/16-16 UNF internal thread specification
• 0.47 inch cutting diameter with 1.125 inch length of cut for adequate thread engagement depth
• 0.5 inch shank diameter for compatibility with standard end mill holders and collet chucks
• No coolant-through design; external coolant application required for optimal chip management

Compatibility

Designed for use on CNC milling machines capable of helical interpolation, producing 11/16-16 UNF internal threads. Compatible with standard 1/2 inch end mill holders, ER collets, and hydraulic chucks.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC programmer familiar with thread milling cycles and helical interpolation G-code. Verify spindle speed, feed rate, and helical pitch programming against the tool manufacturer's cutting data before running the first part. Ensure the tool is seated fully and securely in the holder and runout is checked before beginning the cut. External flood or mist coolant should be directed at the cutting zone to assist chip evacuation since this tool does not have coolant-through capability.
