Threading Tools ShimShim Pitch (mm) Dif cult-to-Machine Area SEC-Threading Tools SSTE Type / SSTI Type ■ Shim Selection If the pitch is large or the threading diameter is small, the threading lead angle will become large and the effective relief angle will become small. A A It is ideal to set the threading insert so that both right and left relief angles are equal. Shim Insert Therefore, it is necessary to select an appropriate shim based on the thread pitch Insert T1 ≈ Lead Angle and effective diameter using the table below. Shim (Ideal Setup) T2 : Shim Angle Lead Angle Cross Section A-A F ■ Shim Selection Procedure① Choose from [Right-Hand Thread / Left-Hand Thread] in the table.② Locate the required threading "pitch".T1=4.5° For External Diameters: YE3-3P For Internal Diameters: YI3-3PT1=3.5° For External Diameters: YE3-2P For Internal Diameters: YI3-2P T1=2.5° For External Diameters: YE3-1P For Internal Diameters: YI3-1P ③ Locate the cell with the required "Effective Diameter" range. ④ Confirm the part no. at the "Shim" row above the corresponding D D D "Effective Diameter" cell located previously. If the shim part no. is 3.0 T1=1.5° For External Diameters: YE3 For Internal Diameters: YI3 different from the one currently in use, change to the correct one. * Standard shim supplied with holder 2.0 Example: When machining a M16x2.0 external right-hand thread, the pitch diameter is 14.701mm. In the table below, locate [2.0]mm underthe "Pitch" column then move along the row to the right to locate1.0 T1=0.5° For External Diameters: YE3-1N For Internal Diameters: YI3-1N the required "Effective Diameter" range [11.4 - 17.4]mm. As such, the correct shim should be [YE3-1P], shown in the corresponding cell under the "External" row above. 0 10 20 30 40 50 60 70Effective Diameter of Threading Hole (mm) ● Pitch (mm) Right-hand/Left-hand Thread For Right-hand Thread For Left-hand Thread Lead Angle 4.5° 3.5° 2.5° 1.5° 0.5° -0.5° -1.5° External YE3-3P YE3-2P YE3-1P YE3* YE3-1N YE3-2N YE3-3N Internal YI3-3P YI3-2P YI3-1P YI3* YI3-1N YI3-2N YI3-3N Shim Angle (T1) 3° 2° 1° 0° -1° -2° -3° Pitch (mm) Effective Diameter (mm) 0.5 1.9 - 2.2 2.2 - 2.8 2.8 - 4.3 4.3 - 11.4 > 11.4 > 11.4 11.4 - 4.3 0.75 2.8 - 3.3 3.3 - 4.3 4.3 - 6.5 6.5 - 17.1 > 17.1 > 17.1 17.1 - 6.5 1.0 3.8 - 4.3 4.3 - 5.7 5.7 - 8.7 8.7 - 22.8 > 22.8 > 22.8 22.8 - 8.7 1.25 4.7 - 5.4 5.4 - 7.1 7.1 - 10.9 10.9 - 28.5 > 28.5 > 28.5 28.5 - 10.9 1.5 5.7 - 6.5 6.5 - 8.5 8.5 - 13.0 13.0 - 34.2 > 34.2 > 34.2 34.2 - 13.0 1.75 6.6 - 7.6 7.6 - 10.0 10.0 - 15.2 15.2 - 39.9 > 39.9 > 39.9 39.9 - 15.2 2.0 7.6 - 8.7 8.7 - 11.4 11.4 - 17.4 17.4 - 45.6 > 45.6 > 45.6 45.6 - 17.4 2.5 9.5 - 10.8 10.8 - 14.2 14.2 - 21.7 21.7 - 57.0 > 57.0 > 57.0 57.0 - 21.7 3.0 11.4 - 13.0 13.0 - 17.1 17.1 - 26.0 26.0 - 68.4 > 68.4 > 68.4 68.4 - 26.0 ● TPI (threads/inch) Right-hand/Left-hand Thread For Right-hand Thread For Left-hand Thread Lead Angle 4.5° 3.5° 2.5° 1.5° 0.5° -0.5° -1.5° External YE3-3P YE3-2P YE3-1P YE3* YE3-1N YE3-2N YE3-3N Internal YI3-3P YI3-2P YI3-1P YI3* YI3-1N YI3-2N YI3-3N Shim Angle (T1) 3° 2° 1° 0° -1° -2° -3° TPI (Threads/Inch) Effective Diameter (mm) 32 3.0 - 3.3 3.3 - 4.6 4.6 - 6.9 6.9 - 18.0 > 18.0 > 18.0 18.0 - 6.9 28 3.0 - 3.8 3.8 - 5.1 5.1 - 7.9 7.9 - 20.8 > 20.8 > 20.8 20.8 - 7.9 27 3.6 - 4.1 4.1 - 5.3 5.3 - 8.1 8.1 - 21.3 > 21.3 > 21.3 21.3 - 8.1 24 4.1 - 4.6 4.6 - 6.1 6.1 - 9.1 9.1 - 24.4 > 24.4 > 24.4 24.4 - 9.1 20 4.8 - 5.6 5.6 - 7.1 7.1 - 10.9 10.9 - 29.0 > 29.0 > 29.0 29.0 - 10.9 18 5.3 - 6.1 6.1 - 8.1 8.1 - 12.4 12.4 - 32.5 > 32.5 > 32.5 32.5 - 12.4 16 5.8 - 6.9 6.9 - 8.9 8.9 - 13.7 13.7 - 35.8 > 35.8 > 35.8 35.8 - 13.7 14 6.9 - 7.9 7.9 - 10.2 10.2 - 15.7 15.7 - 41.1 > 41.1 > 41.1 41.1 - 15.7 13 7.4 - 8.4 8.4 - 11.2 11.2 - 17.0 17.0 - 44.7 > 44.7 > 44.7 44.7 - 17.0 12 8.1 - 9.1 9.1 - 12.2 12.2 - 18.5 18.5 - 48.8 > 48.8 > 48.8 48.8 - 18.5 11.5 8.4 - 9.7 9.7 - 12.4 12.4 - 19.3 19.3 - 50.3 > 50.3 > 50.3 50.3 - 19.3 11 8.9 - 9.9 9.9 - 13.2 13.2 - 20.1 20.1 - 52.6 > 52.6 > 52.6 52.6 - 20.1 10 9.7 - 10.9 10.9 - 14.5 14.5 - 22.1 22.1 - 57.9 > 57.9 > 57.9 57.9 - 22.1 9 10.7 - 12.2 12.2 - 16.0 16.0 - 24.4 24.4 - 64.3 > 64.3 > 64.3 64.3 - 24.4 8 11.9 - 13.7 13.7 - 18.0 18.0 - 27.7 27.7 - 72.4 > 72.4 > 72.4 72.4 - 27.7 * SSTE Type/SSTI Type holders are shipped with shims for lead angle of Y1 = 1.5° (SSTE Type: YE3, SSTI Type: YI3).
