Emuge CU100501.5015 Machine Tap 5/8-11 Unc Nitride Cobalt

Product Description

The EMUGE CU100501.5015 is a 5/8-11 UNC straight-flute machine tap designed for right-hand threading in demanding ferrous and specialty materials. Built from cobalt high-speed steel with a nitride coating, it delivers extended tool life in abrasive and hard-to-tap workpiece materials. The modified bottoming chamfer allows threading close to the bottom of blind holes without the longer lead of a standard plug tap. With 3 flutes and a Class 2BX fit, it produces accurate oversize threads to compensate for material springback. Overall length is 4.331 inches, thread length is 1.063 inches, and shank diameter is 0.480 inches. Suited for use in machine tapping operations on CNC machining centers, drill presses, and tapping machines.

This tap is intended for production and job-shop machining environments where blind-hole threading in tough materials is common. It is well matched to applications involving austenitic iron, ferritic iron, perlitic iron, spheroidal graphite iron, Meehanite iron, bronze, gunmetal, tool steel, low-alloyed casting steel, and high-speed steel workpieces. The straight-flute design makes it appropriate for short-chipping materials where chip evacuation through the flute is reliable. The EMUGE Rekord A-H series is engineered for high-precision threading in these demanding material groups.

Key Features

• Modified bottoming chamfer for threading near the base of blind holes
• Cobalt HSS construction for improved wear resistance in hard and abrasive materials
• Nitride coating reduces friction and extends tool service life
• Class 2BX fit produces controlled oversize threads to offset material springback
• 3-flute straight-flute geometry suited to short-chipping ferrous materials
• Right-hand thread direction, 5/8-11 UNC, no coolant-through requirement

Compatibility

Designed for 5/8-11 UNC blind-hole and through-hole tapping in austenitic iron, ferritic iron, perlitic iron, spheroidal graphite iron, Meehanite iron, bronze, gunmetal, tool steel, low-alloyed casting steel, and high-speed steel. Part of the EMUGE Rekord A-H series.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with machine tapping operations. Ensure the workpiece is securely fixtured and the spindle speed and feed rate are set per the tap manufacturer's guidelines for the specific workpiece material before beginning. Power down and de-energize the machine before changing or inspecting tooling. Do not reverse the tap under load without a tapping head or CNC rigid-tap cycle designed for that purpose.
