Jetbroach cutters are made for faster and improved hole results. Can be run at higher feed and speeds to produce excellent quality and accuracy of holes. Superior cutting time and life when compared with High-Speed steel cutters. Jetbroach cutters are designed for all Atra Ace machines and most other Atra and sid-lock type machines.

key features

• no dead point
• perippheral cutting
• dramatically reduce cutting resistance
• carbide tips for faster cutting
• single pass cutting, no pilot hole required
• annular part does all the work so small cutting resistance reduces drilling time
• cutting of slanted, 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
• can also be fitted to and used with previous Atra Ace models using a hexagon socket set-screw
• improved concentricity extends cutter life! One-touch system consisting of three balls inside the arbor body produces a self-centering effect during cutting to improve cutter performance and life

applications 

• mild steel, cast iron, brass and aluminium drilling
