YINGBA · CARBIDE CNC CUTTING TOOLS
Roughing End Mills
Three-flute geometry for fast bulk removal before the finishing pass.
3 flute · 6 to 16 mm shanks
Quick answer: a roughing end mill is built to remove material quickly rather than to leave a finished surface. The three-flute geometry gives a strong, stable cut and a larger chip load per pass, so the bulk of the material is cleared before a finer tool finishes the job. It is used on MDF, plywood, solid wood, acrylic, PVC, ABS and composite boards.
Materials and machines
- Materials: MDF, plywood, solid wood, glued timber, bamboo board, acrylic, PVC, ABS board, two-colour engraving board, PP board
- Machines: CNC engraving machines, CNC milling machines, precision engraving machines, engraving-milling machines
Feed rate, spindle speed and depth of cut must be matched to the tool diameter, material, machine rigidity and workholding. These are application-specific and are confirmed for each order.

Frequently asked questions
What is a roughing end mill used for?
Removing bulk material quickly before a finishing pass, in MDF, plywood, solid wood, acrylic, PVC, ABS and composite boards. It is not intended to leave a finished surface on its own.
Why three flutes?
Three flutes give a stronger, more stable cut than a single or two-flute tool while still clearing chips, which suits heavier material removal on a rigid machine.
Can it replace a finishing tool?
No. Use the roughing end mill to clear material and then finish with the geometry that matches the edge quality you need.
Which machines is it used on?
CNC engraving machines, CNC milling machines, precision engraving machines and engraving-milling machines.
Can I order custom sizes?
Yes. Cutting diameter, cutting length and overall length can be produced to your drawing.
