The coarse thread design allows for efficient chip removal and improved stability during operation, making it ideal for heavy-duty tasks in demanding environments.
Extended Shank Length
With an extra shank length of 8 inches, this mandrel enhances reach and versatility, accommodating deeper or challenging setups while maintaining precision and ease of use.

Pro-Graad Mandrels Editorial Review
The Porting Mandrel 8, CR-9-8 Premium HSS High Speed Steel Coarse Thread Extra Shank Length Cartridge & Spiral Roll Mandrel has garnered a mix of positive and negative feedback from users, showcasing its performance and overall quality in various applications. Many customers appreciate the craftsmanship and usability of the mandrel, noting that it does its job effectively, especially for those with mechanical experience. The durability and reasonable pricing also received praise, indicating that the product offers good value for money. Users who have employed the mandrel highlight its potential longevity, asserting that if used correctly, it could serve them well for an extended period. However, the product's description as high-speed steel has raised some concerns among users, with at least one customer reporting that it bends and dents easily, which conflicts with the expected robustness associated with high-speed steel products. This discrepancy suggests that while the mandrel performs well under typical usage, its material properties may not fully align with customer expectations for high-performance tools. Overall, the Porting Mandrel 8 appears to be a solid choice for mechanics and blacksmithing enthusiasts, assuming its limitations are acknowledged. **
