feed direction towards the chuck (standard helix )

To determine catalog number replace (*) asterisk with the number 3 or 4. (3 = 3/8 I.C. or 4 = 1/2 I.C.)

0° to 1° = SMYI*1N

1° to 2° = SMYI*

2° to 3° = SMYI*1P

3° to 4° = SMYI*2P

0° to 1° = SMYE*1N

1° to 2° = SMYE*

2° to 3° = SMYE*1P

3° to 4° = SMYE*2P

0° to 1° = SMYE*1N

1° to 2° = SMYE*

2° to 3° = SMYE*1P

3° to 4° = SMYE*2P

0° to 1° = SMYI*1N

1° to 2° = SMYI*

2° to 3° = SMYI*1P

3° to 4° = SMYI*2P

feed direction away from the chuck (reverse helix )

To determine catalog number replace (*) asterisk with the number 3 or 4. (3 = 3/8 I.C. or 4 = 1/2 I.C.)

0° to -1° = SMYI*2N

-1° to 2° = SMYI*3N

0° to -1° = SMYE*2N

-1° to 2° = SMYE*3N

0° to -1° = SMYE*2N

-1° to 2° = SMYE*3N

0° to -1° = SMYI*2N

-1° to 2° = SMYI*3N
