MAPAL HPR300 Large-Diameter Reamer

Reduced costs due to innovative reconditioning The HPR300 reaming system for large diameters convinces with the fact that the brazed tools can be re-tipped and re-coated far more quickly and less expensively. Clamping jaws securely clamp the cutting edges as blanks.

Key Features

• Reduced costs due to innovative reconditioning The HPR300 reaming system for large diameters convinces with the fact that the brazed tools can be re-tipped and re-coated far more quickly and less expensively.
• Clamping jaws securely clamp the cutting edges as blanks.
• Then the diameter and cutting lead geometry are ground with high precision.
• For reconditioning, the worn cutting edges can be easily and quickly replaced with new cutting edge blanks and again ground to the original quality with μ precision.
• The tool body and in particular the shank retain their original, high accuracy.
• On the replacement of the cutting elements, the tool body is not subjected to any thermal loads whatsoever and complex cleaning processes are not required.
• On average, brazed tools can be reconditioned a maximum of four times, while the HPR300 reamers can be re-tipped at least ten times.
• As such, the tools pay for themselves already after the first few reconditioning cycles and provide significant cost savings over the entire service life without degradations in the performance compared with brazed tools.
