Product Description

Introducing The 1/4″ Oh, Jenny – a precision tool designed to deliver exceptional performance when cutting plastics and other non-ferrous materials on both hobbyist and industrial-grade CNC machines. Designed with custom tool geometry, this bit excels in machining pockets and profiles with a superior finish.

Unlike standard CNC bits, the Oh, Jenny is optimized for materials that require efficient chip evacuation and reduced heat buildup.

Ideal for:

Acrylic
HDPE / PVC
Polycarbonate
Aluminum (light passes)
Other non-ferrous materials
The O-flute design clears chips quickly, helping prevent melting, edge buildup, and poor finishes.
