3.175×22 Two Straight Flute Bits for Deep CNC Routing
The 3.175×22 Two Straight Flute Bits are long-reach solid carbide CNC cutters for routing EVA foam, MDF, plywood, hardwood, laminated board, acrylic, PVC and other compatible sheet materials. Two straight cutting edges provide balanced cutting action, while the open flute geometry supports chip evacuation in grooves, pockets and profile cuts.
Product dimensions and geometry
- Cutting diameter: 3.175 mm
- Cutting length: 22 mm
- Cutting geometry: two straight flutes
- Tool material: wear-resistant carbide
Why use a long straight-flute cutter?
The 22 mm cutting length is suitable for fine profiles, grooves and pockets in common woodworking and sign-making sheet materials. Straight flutes provide a neutral cutting action when the workpiece should not be strongly lifted or pressed down. The compact 3.175 mm diameter supports detailed paths, but the machine, holder and cutting parameters must still provide adequate rigidity.
Recommended CNC applications
- Detailed profile cutting in MDF and engineering plastics
- Grooving and pocketing in plywood, Formica and laminated panels
- Machining thick acrylic or PVC sheet after a parameter test
- Sign making, pattern work and CNC engraving operations
Setup and cutting guidance
Clean the collet and shank before installation, minimize tool overhang and confirm the 8 mm shank is compatible with the holder. Secure the material firmly and verify safe clearance around clamps and fixtures. Start with conservative spindle speed, feed rate and depth per pass. Increase productivity only after checking sound, spindle load, chip shape and surface quality.
Efficient chip removal is especially important in deep slots. Use dust extraction or an air system suitable for the machine and material. Do not allow chips to pack around the cutter, because recutting can raise temperature and shorten tool life. For foam and plastics, adjust feed so the cut produces chips instead of melted residue.

Frequently asked questions
What does 3.175×22 mean?
It identifies a 3.175 mm cutting diameter and a 22 mm cutting length.
Why should small-diameter tools use controlled cuts?
A small-diameter cutter can deflect under heavy engagement, so moderate step-down and stable clamping help control vibration and finish.
Can JEEFOO recommend parameters?
Yes. Provide the workpiece material, CNC machine, spindle speed range, depth and desired finish for application review.
