Frequently Asked Questions
1. What is the use of a Set Screw in End Mill Holders?
The Set Screw locks the cutting tool in place, ensuring it doesn’t slip during operation. It provides strong holding power, making it ideal for roughing or high-torque machining.
2. Are Set Screws included with the End Mill Holders?
Yes, every PACTools End Mill Holder includes a high-quality Set Screw designed to perfectly match the holder and provide a reliable, secure fit.
3. How tight should I make the Set Screw?
Tighten firmly using a torque wrench if possible. Over-tightening can cause tool shank damage, while under-tightening may lead to tool slippage or misalignment. For more guidance, you can contact us at +1 262-282-2456.
4. Can PACTools Set Screws be replaced?
Yes, they can be easily replaced when worn or stripped. Using new, high-strength screws helps maintain consistent tool holding performance.
5. What materials are PACTools Set Screws made of?
They are made from hardened alloy steel to resist wear and provide long-lasting durability, even under frequent tool changes.
6. What is an HSK Coolant Tube?
An HSK Coolant Tube directs coolant through the holder directly to the cutting edge, keeping the tool cool and reducing chip buildup during machining.
