Description
YG-1 E5K74902 Solid Carbide Miniature 3 Flute 30 Degree Helix Ball Nose End Mill 0.5 x 1/8 x .060 x 1-1/2
L. Dewitt's SKU #: E5K74902 | Mfr Part #: E5K74902Miniature machining does not forgive vague tooling data. Small implants, electronics features, jewelry details, watch components, aerospace parts, and telecom components need the right diameter, flute count, coating, and length of cut before the tool reaches the spindle. YG-1 Miniature End Mills help maintenance teams, CNC programmers, and industrial buyers select solid carbide detail tools for clean, burr-free finishes and close-tolerance work.
- Medical, electronics, jewelry, watchmaking, and aerospace teams machining small components, fine features, and intricate details.
- CNC programmers and machinists matching miniature square or ball nose geometry to fine detail toolpaths.
- Maintenance and tooling managers replacing miniature YG-1 carbide tools by EDP, coating, flute count, and exact dimensions.
- Industrial buyers comparing uncoated and AlTiN-coated 2 flute, 3 flute, and 4 flute miniature variants before checkout.
E5K74902: YG-1 Miniature 3 flute miniature ball nose solid carbide end mill with Uncoated. Use this model when the operation calls for 3D contouring, miniature profiling, fine detail finishing, and small-radius work and the listed dimensions match the holder, workpiece, reach requirement, and cutting conditions.
Why This Model
Use this miniature end mill when the job requires a center-cutting solid carbide tool for precise detail machining. The selection decision should be based on cutting edge shape, flute count, coating, cutting diameter, shank diameter, length of cut, overall length, work material, machine rigidity, and tolerance requirement before the tool is added to the job.
