Rationalized Hole-cutting
Genuine one-touch cutters

Nitto Kohki has developed the one-touch replacement system for Jetbroach carbide-tipped annular hole cutters. They are designed as one-touch types to be mounted and removed without the use of a tool. This reduces the time needed for hole cutting.

Jetbroach Cutters are far better than twist drills:

• No dead point
• Peripheral cutting
• Blade cutting resistance reduced by 50%
• Available size: 17.5mm - 100mm dia.

A guide to the selection of circumferential cutting speeds:

Jetbroach Cutter Features

• Single pass-cutting, no pilot hole required
• Annular part does all the work so small cutting resistance reduces drilling time
• Cutting of slated, elongated and edge holes is now possible
• Fractional and metric cutter sizes to suit wide range of applications
• Produces little slag and few chips for easy disposal
• Carbide tips for sharp cutting edges
• Can also be fitted to and used with previous Atra Ace models using a hexagon socket set-screw
• Improved concentricity extends cutter life!    Cutter holding system consisting of three balls inside the arbor body produces a self-centering effect during cutting to improve cutter performance and life.

Self-centering effect mechanism to extended cutter life.
