The new RIPPER 3-Flute Roughing End Mills have been specifically designed to cut down your long-duration cycle times and increase your shop efficiency! Use this tool to quickly gouge out the majority of your hardwood pockets, roughing passes for 2.5 and 3D carves, and finish rouging 5x faster than a regular end mill!
These tools will not produce a beautiful finish - they are optimized for speed.
Like all of our solid Japanese carbide CNC tools, this one is also DLC (Diamond-Like Carbon) Coated to maximize its lifespan.

All HCT bits are designed for cutting wood, non-ferrous metal (aluminum/brass/soft metals), and synthetic/plastic-based materials like epoxy and sheet plastics. Bit performance varies with machine type, feeds/speeds set, and the stock material.
Our CNC bits are made from solid Japanese carbide.

NOT EVERY CNC IS THE SAME.
HCT always recommends adjusting feeds & speeds that best suit your CNC.
- Start slow and ramp up your feed until your machine experiences chatter.
- Adjust and save your settings for each type of material you machine.
