Description
YG-1 GM811200 X-Power Pro 4 Flute Short Length End Mill 20.0 x 20.0 x 38.0 x 105.0
L. Dewitt's SKU #: GM811200 | Mfr Part #: GM811200Mold, 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.
GM811200: YG-1 X-Power Pro 4 flute short length square end solid carbide end mill with Y-Coating. Use this model when the operation calls for square-end milling where the selected flute count, length style, helix, and dimensions match the programmed operation 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
- slotting, profiling, side cutting, finishing, and general mold and die machining
- 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

Common Questions
What is the YG-1 GM811200?
GM811200 is an X-Power Pro short length square end Y-coated solid carbide end mill for mold and die, pre-hardened steel, alloy steel, tool steel, and cast-iron machining applications.
What materials use X-Power Pro end mills?
X-Power Pro tools are selected for pre-hardened steels up to HRc 55, mold steels, tool steels, alloy steels, hardened-compatible steels, and cast iron when the selected geometry and cutting parameters match the job.
How do I confirm the correct replacement?
Match the EDP GM811200, tool style, flute count, cutting edge shape, cutting diameter, shank diameter, neck or reach details, length of cut, and overall length against the existing tool or programmed job requirements.
How should this end mill be used?
Use it in a rigid setup with the correct holder, dry or wet cutting strategy, work material, toolpath, chip evacuation plan, and cutting parameters for the selected X-Power Pro geometry.
What results should this product support?
When selected correctly, this X-Power Pro end mill supports a cleaner tooling workflow: faster SKU matching, clearer setup checks, fewer wrong-tool decisions, and more confidence before the tool is ordered or replaced.
