Overview
All-blade core drills are constructed with the cutting edge entirely composed of grindstone and without a base part, enabling extended tool life and an extremely thin cutting edge that improves processing quality.

Features

• All-Blade structure
  • Blade thickness can be reduced compared with electrodeposited and sintered tools
• Significant improvement in tool life
  • Entire blade composed of grindstone can provide tool life several tens of times longer than single-layer electrodeposited tools (depending on processing conditions)
  • Tool life also multiple times longer than sintered tools (depending on processing conditions)
• Improved processing quality
  • Thinner blade reduces chipping and improves dimensional quality compared with electrodeposited and sintered tools
• Reduction of processing time
  • Double core drill enables simultaneous machining of inner and outer diameters, improving consistency and shortening cycle time
• Customization possible
  • Tool diameter, shank diameter, diamond grain size and other parameters can be customized to application
