Finding the right end mill manufacturer is crucial for achieving precision, productivity, and profitability. India’s cutting tool market in 2025 is stronger than ever, with strong contributions from global leaders and local innovators.
A 2 flute end mill has more space for chip clearance, making it ideal for soft materials like aluminum or plastic. A 4 flute end mill has more cutting edges, offering better finish and rigidity, perfect for harder materials like steel or titanium.
The standard drill bit size for a 1/4-20 UNC tap is a #7 drill bit (0.2010 inches / 5.105 mm), equivalent to 13/64 inches (0.2031 inches) for practical purposes. This size delivers approximately 75% thread engagement, balancing strength and tap life for most materials.
Find the best end mills for aluminum by considering flute count, material, coatings, and geometry for smoother cuts and longer tool life.
