YG-1 HPI88945 X1-EH 2 Flute 35 Degree Helix End Mill .6 x 4 x 0.5(6) x 45
L. Dewitt's SKU #: HPI88945 | Mfr Part #: HPI88945Finishing hardened steel is unforgiving: the wrong end mill can create chatter, poor surface finish, edge chipping, and avoidable rework. YG-1 X1-EH end mills help maintenance teams, CNC programmers, and industrial buyers select a premium solid carbide tool for high-hardened steel work by geometry, reach, coating, edge style, and exact dimensions.
- Die and mold teams selecting finishing tools for hardened steel cavities, ribs, corners, and profiles.
- CNC programmers and machinists matching flute count, helix, corner geometry, reach, and dimensions to the programmed toolpath.
- Maintenance and tooling managers replacing X1-EH tools by EDP, tool style, and exact geometry.
- Industrial buyers comparing X1-EH variants before checkout with enough practical detail to avoid wrong-tool orders.
HPI88945: YG-1 X1-EH 2 flute square end solid carbide end mill with C-Coating. Use this model when the operation calls for profiling, slotting, side cutting, face milling, rib processing, and fine-finishing work and the listed dimensions match the holder, workpiece, reach requirement, and cutting conditions.
Why This Model
Use this X1-EH model when the job requires a fine-finishing solid carbide end mill for high-hardened steel applications. The selection decision should be based on cutting edge shape, flute count, helix angle, cutting diameter, shank diameter, length of cut, reach, and overall length before the tool is added to the job.

What This Solves
- Better finishing decisions. Geometry, reach, and edge style are visible so programmers can match the tool to the finishing operation.
- Faster replacement matching. EDP, dimensions, flute count, coating, and tool style are structured for repeat ordering.
- Reduced wrong-tool risk. Selection checks help buyers confirm holder fit, reach, material, and cutting setup before checkout.
- More practical hardened-steel planning. The description connects the product to die and mold applications, rib work, profiling, and finishing needs.
Common Applications
- Fine-finishing and semi-finishing in high-hardened steel
- Die and mold machining, rib processing, and contour work
- Profiling, slotting, side cutting, and face milling where the selected geometry is appropriate
- Hardened steel applications in X1-EH 40-60 HRc and 50-70 HRc selection ranges
- Maintenance replacement when an existing X1-EH EDP or geometry must be matched
