JETBROACH Cutters


Tungsten Carbide Tipped Annular Cutters
For simplicity, one-touch cutter replacement needs no tools

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:

 
 feet/min
m/min 
 Stainless Steel
 65 - 131
20-40
 Mild Steel
 98 - 164
 30-50
 Cast Iron
 98 - 164
 30-50
 Brass

 164 - 229

 50-70
 Aluminum
 229 - 295
 70-90

Test Drilling is very often the only way to determine the machinability of difficult materials. Use a small size cutter wherever possible in order to minimize trial costs.

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.
