How to use this table to find the feed per tooth (IPT): FOR SOLID 1. Find your Alpha Code on the product page (example: 653K, “K“ is the Alpha Code). CARBIDE 2. Find the closest diameter for your cutting application in the top row of the table. MILLING 3. Find your Alpha Code in the left column of the table. CUTTERS ONLY 4. The intersection (cell) of the Diameter and Alpha Code is the feed per tooth (IPT). ø DC [inch] 1/16 3/32 1/8 5/32 3/16 7/32 1/4 5/16 3/8 7/16 1/2 9/16 5/8 3/4 7/8 1 .0625 .0938 .1250 .1563 .1875 .2188 .2500 .3125 .3750 .4375 .5000 .5625 .6250 .7500 .8750 1.0000 A .0001 .0001 .0002 .0002 .0002 .0002 .0003 .0003 .0004 .0005 .0005 .0006 .0007 .0008 .0010 .0011 B .0001 .0001 .0002 .0002 .0002 .0002 .0003 .0003 .0004 .0005 .0005 .0006 .0007 .0008 .0010 .0011 C .0001 .0001 .0002 .0002 .0002 .0002 .0003 .0003 .0004 .0005 .0005 .0006 .0007 .0008 .0010 .0011 D .0001 .0001 .0002 .0002 .0002 .0003 .0004 .0004 .0004 .0005 .0006 .0006 .0007 .0008 .0010 .0011 E .0001 .0001 .0002 .0003 .0004 .0004 .0005 .0006 .0006 .0007 .0007 .0009 .0009 .0011 .0012 .0013 F .0001 .0002 .0002 .0004 .0005 .0006 .0006 .0007 .0009 .0009 .0011 .0012 .0013 .0015 .0017 .0019 G .0002 .0002 .0004 .0006 .0007 .0007 .0009 .0010 .0012 .0013 .0015 .0016 .0017 .0020 .0023 .0025 Feed rates I .0002 .0003 .0005 .0007 .0009 .0011 .0012 .0014 .0016 .0018 .0020 .0022 .0024 .0028 .0031 .0035 J .0003 .0004 .0007 .0010 .0012 .0014 .0017 .0019 .0022 .0024 .0027 .0030 .0032 .0037 .0043 .0047 K .0004 .0006 .0009 .0014 .0016 .0019 .0022 .0025 .0029 .0032 .0036 .0040 .0043 .0050 .0056 .0063 N .0005 .0007 .0011 .0019 .0022 .0025 .0029 .0034 .0038 .0043 .0048 .0053 .0057 .0066 .0075 .0083 O .0006 .0010 .0015 .0024 .0029 .0034 .0039 .0045 .0051 .0057 .0063 .0070 .0076 .0088 .0100 .0111 P .0008 .0014 .0020 .0033 .0038 .0045 .0052 .0060 .0068 .0076 .0084 .0094 .0100 .0117 .0133 .0148 R .0011 .0018 .0027 .0043 .0051 .0060 .0069 .0080 .0091 .0101 .0112 .0125 .0134 .0156 .0177 .0197 S .0015 .0024 .0036 .0058 .0067 .0080 .0091 .0106 .0120 .0135 .0149 .0166 .0178 .0207 .0236 .0263 113
