1/16" O-Flute Endmill — Fine Detail on Plastics, No Melting

Standard bits melt or gum up on plastic, especially at small diameters where heat builds fast. This 1/16" O-flute endmill's single-flute geometry evacuates chips efficiently, cutting clean through plastics, acrylics, PVC, HDPE, and ACM without material welding to the tool.

100% carbide construction holds a sharp edge through the slow, careful passes fine detail work demands.

Specs
  • Cut diameter: 1/16″
  • Shank: 1/8″
  • Length: 1.6″
  • Flutes: 1
  • Flute length: 0.325″
Settings
  • Speed (rpm): 18,000
  • Feed: 20 ipm
  • Plunge: 15 ipm
  • Depth per pass: 0.03″
  • Stepover: 30%

Best for fine detail work in plastics and other heat-sensitive materials.

What is a 1/16″ O-flute for?

Fine detail in plastics. Its single-flute geometry clears chips efficiently, so it cuts plastics, acrylics, PVC, HDPE and ACM cleanly without material welding to the tool.

What speeds and feeds should I use?

Start at 18,000 rpm, 20 ipm feed, 15 ipm plunge, 0.03″ depth per pass and a 30% stepover.

Why is the depth per pass so shallow?

Heat builds fast at small diameters, and plastics are heat-sensitive. Shallow, careful passes are what this bit is built for.

What materials can I cut?

Plastics, acrylics, PVC, HDPE and ACM.

What are its dimensions?

1/8″ shank, 1.6″ overall length, one flute and a 0.325″ flute length, in 100% carbide.
