Emuge C0459601.0112 Spiral Flute Tap M12x1.75 Cobalt Ticn

Product Description

The EMUGE C0459601.0112 is a spiral flute tap designed for blind hole threading in metric applications. It carries an M12x1.75 thread size with a modified bottoming chamfer, making it well-suited for threading close to the bottom of a blind hole without sacrificing thread engagement. The tap is manufactured from cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, which increases surface hardness and reduces heat buildup during cutting. With 3 right-hand flutes in a slow-helix configuration at a 15-degree helix angle, it provides controlled chip evacuation in a variety of workpiece materials. Machinists and toolroom professionals working with production or job-shop threading operations are the primary users of this tap.

This tap is engineered for blind hole threading in steel, stainless steel, aluminum and non-ferrous metals, and high-temperature alloys including titanium alloy. The slow spiral flute geometry and TiCN coating make it particularly effective in tougher workpiece materials where heat and tool wear are primary concerns. It belongs to the EMUGE Rekord D series, a line developed for demanding threading applications across a range of material groups. The 6HX class of fit delivers a tight tolerance thread suitable for precision assemblies. Overall length is 110 millimeters with a 24 millimeter thread length, accommodating standard blind hole depths for M12 applications.

Key Features

• M12x1.75 metric thread with modified bottoming chamfer for threading near the base of blind holes
• Cobalt HSS construction provides elevated heat and wear resistance compared to standard M2 steel
• TiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 3-flute slow spiral design at 15-degree helix angle promotes controlled chip flow in blind hole conditions
• 6HX class of fit produces close-tolerance threads for precision fastener applications
• Rekord D series construction with right-hand thread and right-hand flute direction

Compatibility

Designed for blind hole threading in steel, stainless steel, aluminum and non-ferrous metals, and high-temperature alloys including titanium alloy. Material application codes P, M, N, and S are supported per the supplier specification.

Installation Notes

This tap is installed and operated by machinists, toolroom technicians, or CNC operators on drill presses, CNC machining centers, or tapping machines. Ensure the workpiece is securely clamped and the pre-drilled hole diameter matches the correct tap drill size for M12x1.75 before starting. Coolant through is not supported on this tap, so apply cutting fluid externally and clear chips periodically to prevent tap breakage in blind holes. Follow machine tool manufacturer guidelines for spindle speed and feed rate when threading cobalt taps in hardened or high-temperature alloy materials.
