1 /4 Inch 4 Flute Square End Mill, Straight Shank HSS End Mill Cutter for CNC Milling Machine, Metalworking Cutting Tool 1 /4″ Working Diameter 20mm LOC

Features

• Precision 4 Flute Design Efficient Chip Removal: The 4-flute configuration provides improved surface finish and increased feed rates compared to 2-flute designs. Ideal for finishing passes on steel, cast iron, and harder materials.
• Solid HSS Construction General Purpose Metal Cutting: Made from high-speed steel (HSS), this end mill offers good wear resistance and heat tolerance. Suitable for machining materials with hardness above 30 HRC.
• 1/4 Inch Shank & Cutting Diameter Standard Size: Features a 1/4 inch straight shank and 1/4 inch cutting diameter. Compatible with most CNC milling machines, drill presses, and manual mills with 1/4 inch collets.
• Square End with 20mm Length of Cut Versatile Applications: Square end design allows for slotting, profiling, and pocketing operations. The precision-ground surfaces provide clean cuts for general machining tasks.
• Heat-Treated & Sharp Ready for Use: Factory-new condition with no chips or damage. Heat-treated for consistent hardness across the cutting surfaces. Perfect for home machine shops, repair work, and light industrial applications.
