Blind hole taps with high spiral flutes are the best thread cutting tools. The ingenious design of the tool geometry and their correspondence between chamfer lengths are compatible with a wide range of materials with few tool variations.

Chamfer. 2-3 threads is standard.
Material. These taps cover the following range of workpiece materials: Free-cutting steels, construction steels, cast steels, heat-treatable steels, spheroidal cast iron up to GGG70 (with restrictions, also GG), forged components, low-alloyed stainless materials, aluminum alloys up to 12% Si.
Coating. Standard type with surface treatment Ne2 (steam-treated). |

|
Chamfer. 2-3 threads.
Material. Tensile strengths of 58,000 to 101,000 psi can be machined. Please refer to EMUGE Tap Finder on page VI through XII for complete information.
Machining. For use on general boring machines, thread cutting units with hydraulic or pneumatic feed control systems and similar machines. Oil lubrication is recommended. |

Application. The "X-design", or back taper, can be applied to any type of blind hole tap. By grinding off the tooth crests on the part of the thread profile behind the chamfer area broken and chipped teeth can be avoided. With critical materials, especially in deep blind hole threads, friction can be drastically reduced. |

Chamfer. 2-3 threads.
Material. The blue ring mark is a visual indication of the cutting edge geometry. Rake and relief angles are designed for machining difficult materials such as stainless steels and acid-resistant steels, heat-treated parts, alloyed steel castings, tool steels and similar materials. |
