Description
YG-1 GM886957 X-Power Pro 2 Flute Ball Nose For Rib Processing End Mill 0.6(R.3) x 4 x 0.9(2) x 45 N.55
L. Dewitt's SKU #: GM886957 | Mfr Part #: GM886957Mold, die, tool steel, alloy steel, pre-hardened steel, and cast-iron jobs need more than a generic carbide end mill. The wrong tool can create chatter, poor finish, edge wear, missed detail, and rework. YG-1 X-Power Pro end mills help maintenance teams, CNC programmers, and industrial buyers select a Y-coated carbide tool by flute count, helix, edge style, reach, length style, and exact dimensions for dry or wet cutting conditions.
- Mold and die teams machining plastic injection molds, die-casting components, automotive parts, electronic parts, and detailed cavities.
- CNC programmers and machinists matching square, corner-radius, ball nose, rib-processing, taper-neck, roughing, and long-reach geometry to the programmed toolpath.
- Maintenance and tooling managers replacing X-Power Pro tools by EDP, coating, flute count, geometry, reach, and exact dimensions.
- Industrial buyers comparing inch and metric X-Power Pro variants before checkout with enough practical detail to avoid wrong-tool orders.
GM886957: YG-1 X-Power Pro 2 flute rib processing ball nose solid carbide end mill with Y-Coating. Use this model when the operation calls for rib processing, mold detail work, and deep-feature machining where reach, geometry, and controlled tool selection matter and the listed dimensions match the holder, workpiece, reach requirement, and cutting conditions.
Why This Model
Use this X-Power Pro model when the job requires a Y-coated solid carbide end mill for pre-hardened steels up to HRc 55, mold steels, alloy steels, tool steels, hardened-compatible steels, or cast iron. The selection decision should be based on cutting edge shape, flute count, helix angle, length style, reach, cutting diameter, shank diameter, length of cut, and overall length before the tool is added to the job.

What This Solves
- Better mold-and-die tooling decisions. Geometry, coating, reach, and edge style are visible so programmers can match the tool to the operation.
- Faster replacement matching. EDP, dimensions, flute count, coating, length style, and tool style are structured for repeat ordering.
- Reduced wrong-tool risk. Selection checks help buyers confirm holder fit, reach, material, machine rigidity, coolant strategy, and cutting setup before checkout.
- More practical production planning. The description connects the product to finish quality, wear resistance, dry or wet cutting, profiling, slotting, roughing, rib processing, and contour work.
Common Applications
- Pre-hardened steels up to HRc 55, mold steels, tool steels, alloy steels, hardened-compatible steels, and cast iron
- rib processing, mold and die details, pocket features, profiling, and finishing work in pre-hardened and hardened-compatible steels
- Mold and die work, plastic injection tooling, die casting, automotive parts, electronic parts, and detailed production machining
- Maintenance replacement when an existing YG-1 X-Power Pro EDP or geometry must be matched
