General-Purpose End Mills — Single End<br />
Series CG , CGD<br />
Series CG Single End, Series CGD Double End, General Purpose<br />
Features<br />
• 10% cobalt submicron grain carbide substrate<br />
• 30° right-hand spiral, right-hand cut helix designed for maximum chip clearance<br />
• Two-, three-, four-, and six-flute configurations available<br />
• Available in square, corner radius, and ball nose end geometries<br />
• Available in multiple lengths<br />
• Offered in inch, standard metric, and DIN metric sizes<br />
Applications<br />
• Use in general milling applications in cast iron, non-ferrous light metals, and plastics, as well as medium- to low-carbon steels.<br />
• Double-end mills offer an economical way to increase productivity.<br />
• Two-flute end mills are generally used for plunging, slotting, and heavy peripheral cuts.<br />
• Three-flute end mills provide a good compromise between the chip clearance of a two-flute end mill with the rigidity and wear resistance<br />
of a four-flute tool; they are especially suited for many slotting operations.<br />
• Four-flute end mills are most commonly used in profiling applications and harder materials than two-flute end mills. Stiffer construction<br />
results in minimal deflection. Four flutes provide good surface finishes and wear-resistant characteristics for excellent size control.<br />
• Feed and speed recommendations are listed on pages 12 and 13.<br />
Use Series CG end mills for finishing applications in these materials:<br />
