Side Lock Tool Holders (also known as Weldon Type Tool Holders) are designed for maximum gripping force and rigidity. They use radial set screws to lock the flat (Weldon shank) of an end mill, making them ideal for heavy-duty milling, roughing operations, and high torque applications where tool pull-out must be avoided.
Asmita Industries manufactures precision Side Lock Tool Holders suitable for Indian CNC workshops and global machining standards.

Advantages Over ER Collet Chucks
- ✔ Higher torque transmission
- ✔ No slippage in heavy cutting
- ✔ Simple & robust design
- ✔ Ideal for roughing end mills
(Note: ER collet chucks are better for finishing; side lock holders excel in rough machining.)
