Description
YG-1 GMK31020 EV Mills 2 Flute 30 Degree Helix Ball Nose End Mill 2 x 6 x 5 x 50
L. Dewitt's SKU #: GMK31020 | Mfr Part #: GMK31020Mill-turn platforms, live-tool lathes, and mixed-material milling work need end mills that are practical to choose and easy to verify. The wrong tool can create vibration, chip evacuation problems, poor finish, and avoidable setup changes. YG-1 EV Mills help maintenance teams, CNC programmers, and industrial buyers select an economical high-performance solid carbide end mill by flute count, helix design, edge style, coating, size system, and exact dimensions.
- Mill-turn and live-tool lathe users needing optimized-length tools for compact setups and common clamping adapters.
- CNC programmers and machinists matching ball nose, square end, corner radius, 2 flute, 3 flute, and 4 flute EV Mills to the programmed toolpath.
- Maintenance and tooling managers replacing EV Mills by EDP, coating, flute count, geometry, measurement system, and exact dimensions.
- Industrial buyers comparing inch and metric EV Mill variants before checkout with enough practical detail to avoid wrong-tool orders.
GMK31020: YG-1 EV Mills 2 flute ball nose solid carbide end mill with Y-Coating and ultra fine grain carbide. Use this model when the operation calls for profiling, contouring, and 3D finishing where ball nose geometry, smooth chip evacuation, and controlled overhang matter and the listed dimensions match the holder, workpiece, overhang, and cutting conditions.
Why This Model
Use this EV Mills model when the job requires an economical high-performance solid carbide end mill for multi-material work, mill-turn platforms, live-tool lathes, or general CNC milling. The selection decision should be based on cutting edge shape, flute count, helix angle, coating, measurement system, cutting diameter, shank diameter, length of cut, and overall length before the tool is added to the job.

What This Solves
- Better multi-material tooling decisions. Geometry, flute count, coating, and size system are visible so programmers can match the tool to the operation.
- Faster replacement matching. EDP, dimensions, flute count, helix design, and edge style are structured for repeat ordering.
- Reduced wrong-tool risk. Selection checks help buyers confirm holder fit, overhang, material, machine rigidity, coolant strategy, and cutting setup before checkout.
- More practical setup planning. The description connects the product to chip evacuation, reduced vibration, surface finish, mill-turn platforms, live tooling, slotting, profiling, and finishing work.
Common Applications
- Non-alloy steels, low alloy steels, high alloy and tool steels, stainless steels, cast irons, copper alloys, heat-resistant alloys, titanium alloys, and compatible hardened steel applications
- profiling, contouring, finishing, mill-turn milling, live-tool lathe milling, and multi-material ball-nose work
- Mill-turn platforms, live-tool lathes, machining centers, slotting, side milling, profiling, finishing, and multi-material production work
- Maintenance replacement when an existing YG-1 EV Mills EDP or geometry must be matched
