Selling Points of Retention Knob (Pull Stud)

1. High-strength alloy steel & excellent fatigue resistance (Core Selling Point)Made of premium alloy steel such as 20CrMnTi with carburizing & quenching heat treatment. High tensile strength, resistant to cyclic load during ATC tool change, less risk of fracture for safe machining.

2. Precision machined for stable clamping & low runoutPrecision ground ball taper and thread with tight tolerance. Ensures firm fit between tool holder and spindle, reduces radial runout & cutting chatter, improves workpiece accuracy and surface finish.

3. Protects spindle gripper, cuts maintenance costServes as sacrificial wear part to prevent damage to costly spindle grippers, saving expensive spindle repair.

4. Full specifications & wide compatibilityAvailable for BT30/BT40/BT50, CAT, ISO, MAS403, Mazak standards. 45°/60°/90° angles optional. Standard, through-coolant and extended types fit most CNC machining center tool holders.

5. Through-coolant option for better cooling & chip removalCoolant-through pull studs deliver high-pressure coolant straight to cutting zone, improves chip evacuation and extends tool life, ideal for deep hole & high-speed finishing.

6. Wear & corrosion resistance, long service lifeBlack oxide / hardened surface treatment, anti-rust and resistant to cutting fluid, stable in harsh workshop environment with chips and coolant.

7. Safe locking, prevents tool holder ejectionSecurely locks tool holders, avoids loosening under high-speed and heavy cutting, eliminates risks of tool flying out.

8. Cost-effective & easy replacementLow-cost consumable for tool holders, simple installation & stocking, competitive bulk price.
