Description
YG-1 E2F64905 Sine-Power HSS Co8 6 Flute 30 Degree Helix Center Cut Roughing End Mill 1 x 1 x 3 x 5-1/2 .030 Chamfer
L. Dewitt's SKU #: E2F64905 | Mfr Part #: E2F64905Titanium, titanium alloys, and stainless steels punish standard roughers when heat, chatter, chip evacuation, and tool stability are not controlled. YG-1 Sine-Power end mills are HSS Co8 high-performance roughers built for aerospace, power-generation, maintenance, and production teams that need efficient material removal in difficult-to-machine materials.
- Aerospace and power-generation shops roughing titanium, titanium alloys, and stainless steels.
- CNC programmers and machinists needing large depths of cut in slotting, profiling, and axial machining operations.
- Maintenance and tooling teams replacing large-diameter cobalt roughers by EDP, flute count, chamfer, and exact dimensions.
- Industrial buyers comparing 4 flute and 6 flute Sine-Power options for stability, chip control, and difficult-material roughing.
E2F64905: YG-1 E2F64905 Sine-Power HSS Co8 6 Flute 30 Degree Helix Center Cut Roughing End Mill 1 x 1 x 3 x 5-1/2 .030 Chamfer is a YG-1 Sine-Power 6 flute HSS Co8 roughing end mill with 30 degree helix, center-cutting geometry, sinusoidal cutting edges, engineered flute geometry, and chamfered corner protection. Use this model when the operation calls for high metal removal in titanium, titanium alloys, stainless steels, slotting, profiling, or heavy roughing work.
Why This Model
Use this Sine-Power rougher when a standard roughing end mill is not giving enough chip control, stability, or finish quality in difficult materials. The variable face profile, sinusoidal cutting edges, center-cutting geometry, and engineered flute design help reduce heat, friction, vibration, and chatter while supporting heavy slotting and profiling cuts.

What This Solves
- More stable roughing. Engineered flute geometry and 4 or 6 flute construction support heavy cuts in difficult materials.
- Better chip evacuation. Center-cutting geometry and sinusoidal cutting edges support chip formation while reducing heat and friction.
- Reduced chatter risk. Variable face profile geometry helps lower vibration during slotting and profiling.
- Cleaner replacement matching. EDP, flute count, chamfer, cutting diameter, shank diameter, length of cut, and overall length are structured for purchasing and setup checks.
Common Applications
- Titanium, Ti6Al4V, titanium alloys, stainless steels, PH stainless, and difficult stainless applications
- Aerospace, power-generation, toolroom, maintenance, and production roughing workflows
- Slotting, profiling, axial machining, heavy side milling, and large-depth roughing operations
- Replacement of large HSS cobalt roughers where exact diameter, flute count, chamfer, reach, and shank fit matter

Common Questions
What is the YG-1 E2F64905?
E2F64905 is a Sine-Power HSS Co8 roughing end mill designed for high-performance roughing in titanium, titanium alloys, and stainless steels.
When should I use a Sine-Power rougher?
Use Sine-Power when the operation needs efficient metal removal, improved chip formation, reduced vibration, and better stability than a standard rougher in difficult materials.
What results should this product support?
When selected correctly, this tool supports higher confidence in titanium roughing, cleaner chip evacuation, reduced chatter, more stable slotting or profiling, and faster replacement matching.
How do I confirm the correct replacement?
Match EDP E2F64905, flute count, cutting diameter, shank diameter, length of cut, overall length, chamfer, holder fit, work material, coolant strategy, and cutting parameters before ordering.
