  <p>Common carbide end mill sizes include small metric diameters such as 1mm, 2mm and 3mm, general metric sizes such as 4mm, 6mm, 8mm, 10mm and 12mm, and inch sizes such as 1\/8, 1\/4, 3\/8 and 1\/2 inch.<\/p>\r\n        <\/div>\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>How do I choose end mill diameter?<\/h3>\r\n          <p>Choose the end mill diameter according to the slot width, pocket corner clearance, part geometry, workpiece material and required rigidity. For tight corners or small features, smaller diameters or custom tools may be required.<\/p>\r\n        <\/div>\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>What is the difference between flute length and overall length?<\/h3>\r\n          <p>Flute length is the cutting length of the tool, while overall length is the full tool length from tip to shank end. A longer overall length provides more reach, but excessive overhang can increase vibration and deflection.<\/p>\r\n        <\/div>\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>What size end mill should I use for a 1\/4 inch slot?<\/h3>\r\n          <p>A 1\/4 inch end mill can be used as a starting point for a 1\/4 inch slot, but tolerance, material, tool deflection and finishing allowance should be reviewed before final selection.<\/p>\r\n        <\/div>\r\n\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>How do I convert inch end mill sizes to metric sizes?<\/h3>\r\n          <p>\r\n            Multiply the inch size by 25.4 to get millimeters. For example, a 1\/4 inch end mill is approximately 6.35mm.\r\n            You can use the converter on this page for quick metric and inch size reference.\r\n          <\/p>\r\n        <\/div>\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>Do you provide 1mm, 2mm and 3mm end mills?<\/h3>\r\n          <p>Yes.

Smaller ball radius tools can produce finer surface details, while larger tools may be more stable and efficient for broader surfaces.<\/p>\r\n        <\/div>\r\n\r\n        <div class=\"onmy-size-faq-item\">\r\n          <h3>Can you make custom end mill sizes?<\/h3>\r\n          <p>Yes.
