Description
YG-1 JAI38931 Alu-Power HPC 3 Flute 37 Degree. Helix Chip Breaker Corner Radius Coated End Mill 1/2(R.06) x 1/2 x 2-1/2 x 5
L. Dewitt's SKU #: JAI38931 | Mfr Part #: JAI38931Aluminum machining moves fast, but the wrong end mill can create built-up edge, chip packing, heat, chatter, poor finish, and avoidable setup questions. YG-1 Alu-Power HPC end mills help maintenance teams, CNC programmers, and industrial buyers choose a high-performance 3 flute carbide tool for aluminum, aluminum die cast, non-ferrous alloys, and plastics by geometry, coating, reach, and exact dimensions.
- CNC programmers and machinists running aluminum, die cast aluminum, non-ferrous alloys, and plastics at high spindle speeds.
- Production and tooling teams selecting 3 flute geometry for ramping, roughing, slotting, pocketing, side cutting, profiling, and peel milling.
- Maintenance and tooling managers replacing Alu-Power HPC tools by EDP, coating, corner style, reach, and exact dimensions.
- Industrial buyers comparing coated, uncoated, square end, corner radius, ball nose, and chip breaker variants before checkout.
JAI38931: YG-1 Alu-Power HPC 3 flute chip breaker corner radius solid carbide end mill with DLC-coated construction. Use this model when the operation calls for high-speed aluminum milling where chip length control and evacuation matter during heavier roughing, pocketing, slotting, and side-cutting work and the listed dimensions match the holder, workpiece, reach requirement, and cutting conditions.
Why This Model
Use this Alu-Power HPC model when the job requires a high-performance solid carbide end mill for aluminum and compatible non-ferrous materials. The selection decision should be based on cutting edge shape, coating, 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 aluminum-tooling decisions. Geometry, coating, reach, and edge style are visible so programmers can match the end mill to the 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, machine rigidity, coolant strategy, and cutting setup before checkout.
- More practical production planning. The description connects the product to chip evacuation, built-up-edge control, ramping, pocketing, profiling, and high-speed aluminum work.
Common Applications
- Aluminum, aluminum die cast, non-ferrous alloys, copper and brass, plastics, and other compatible non-metallic materials
- high-speed roughing, chip-control pocketing, slotting, side cutting, peel milling, and aluminum production work
- High-speed and high-performance aluminum machining where stable setup, chip evacuation, and finish control matter
- Maintenance replacement when an existing YG-1 Alu-Power HPC EDP or geometry must be matched
