【4 Flutes for Smoother Finishes】The 4-flute design allows for higher feed rates and generates smoother surface finishes onside walls compared to 2-flute end mills.
【Precision Countersinking】The precision ground end produces accurate countersinks or spotfaces, ensuring flat bottoms and screw seating.
【Excellent Toughness & Impact Resistance】HSS material provides superior toughness compared to carbide, reducing chipping riskduring intermittent cuts or onless rigid machines.
