Frequently Asked Questions
1. What exactly is an end mill holder?
An End mill holder is a tool holder designed to securely grip the shank of an end mill using a set screw. PACTools offers durable end mill holders for heavy-duty cutting applications where rigidity is essential.
2. What sizes are endmill holders are available?
At PACTools, End mill holders are available in various sizes, with bore diameters ranging from 1/8″ to 1-1/2″ (or 6 mm to 40 mm in metric). They also come in different projection lengths, like stub, standard, and extended, to suit various machining needs. If you need guidance on which product to order, you can email us at sales@pactoolsusa.com or call our sales team.
3. How is an end mill holder different from a collet chuck?
An End mill holder uses a set screw to grip the tool shank, offering high rigidity, while a collet chuck (like PACTools’ ER holders) uses a collet to provide better concentricity and versatility across different tool size.
4. What shank tolerance is required for proper fit in an end mill holder?
For a seacure fit in end mill holders from PACTools, the tool shank should have an h6 tolerance. This ensures proper contact and prevents slippage during high-speed machining operations.
5. How often should I inspect the bore of the holder?
At PACTools, we recommend inspecting the bore of the holder regularly-ideally after every 40-50 hours of operation, to ensure precision, prevent wear, and maintain optimal tool holding performance. If you need guidance on which product to order, you can email us at sales@pactoolsusa.com or call our sales team.
6. Can I use an end mill holder on CNC and manual machines?
Yes, PAC Tools end mill holders are compatible with both CNC and manual machines, offering strong grip and stability for various milling operations across both platforms.
