4 Coolant Hole Considerations That Help Maximize Round Tool Performance
One of the most effective ways to maximize the performance of a round tool for applications with high heat or high friction is through the use of coolant channels. The ideal configuration of the through holes in the carbide rod blank depends on the requirements of the application of the tool being manufactured. Different hole designs can lead to different benefits for your customer in their application.
When paired with your toolmaking expertise and the proper base carbide grade, the coolant hole configuration can bring a new differentiator for the tooling that you produce. Coolant hole configurations that improve dissipation of heat or maximize chip evacuation can help your tool to excel in challenging or complex customer applications.
This application note explores the role that coolant hole geometry plays in tool design for drills, end mills and reamers. It then details four important characteristics of carbide rod blanks with coolant holes that can be leveraged with your toolmaking expertise to create unique solutions for your market.
The note discusses how coolant hole shape, coolant hole orientation, coolant hole density, and coolant hole entry and exit points can be combined to optimize the performance of your tooling. With Hyperion Materials & Technology’s ability to create custom-shaped coolant channels in straight, helical or spiral grooves, you will be able to effectively meet the unique needs of your end market’s challenging applications. The application note also investigates the trade-offs between efficiency and durability when designing a tool with coolant hole technology.
Hyperion offers carbide rod blanks with coolant holes in its High Performance and Application Specific product series, including in Hyperion grade H10F carbide and AFC Hartmetall grade K40UF.
