Regency® Cobalt End Mill 4 Flute Single End 1/4"

Power through tough alloys with the M42 Cobalt End Mill 4 Flute, Single End, 3/4". The 4-flute configuration and sinusoidal edge geometry allow faster feed rates by producing smaller chips—ideal for roughing operations. Combined with a durable TiN coating and 8% cobalt content, this end mill is perfect for challenging materials like stainless and nickel alloys.
• 4-flute, single-end configuration for higher feed rates
• Unique sinusoidal edge produces smaller chips for rough cuts
• M42 tool steel with 8% cobalt for extended wear resistance
• TiN coating minimizes buildup and improves chip flow
• Designed for abrasive and hard materials
• Made in the USA
• End Mill Tip: More flutes suit harder materials
End Mill Selection: Harder workpieces require a higher number of flutes. Softer material requires fewer flutes.
CAUTION: Any cutting tool may break or shatter under improper use. Government regulations require use of safety glasses and other appropriate safety equipment at all times in the vicinity of use.
