4×22 Two Straight Flute Router Bit is a solid carbide CNC cutter for routing, slotting, trimming and engraving in wood, MDF, plywood, acrylic, PVC, ABS, foam and compatible composite materials. The 4 mm diameter and 22 mm cutting length support narrow profiles and controlled pocket work when machine rigidity, tool projection and cutting parameters are set correctly.
4×22 Two Straight Flute Router Bit Applications
This cutter suits straight grooves, pockets, profile cutting, edge trimming, sign components and general CNC routing. Two straight flutes provide balanced cutting edges and predictable chip formation. The geometry is useful in sheet materials and wood products where a straight cutting action is preferred over an up-cut or down-cut spiral.
Use the 4×22 Two Straight Flute Router Bit for furniture parts, advertising panels, templates, plastic components and small-batch industrial products. Confirm that the 22 mm flute length clears the programmed depth while the shank remains securely held in the collet. Several step-down passes are often safer for deep slots.
CNC Installation and Test Cutting
- Clean the collet, nut and carbide shank before installation.
- Grip the shank securely without clamping on the cutting flutes.
- Minimize projection to reduce vibration and side load.
- Verify spindle runout, workholding and programmed zero position.
- Begin with a shallow test pass and inspect chip shape and edge quality.
- Use extraction or air flow to prevent chips from being recut.
In computer numerical control machining, toolpath accuracy must be combined with practical feed, speed and depth settings. Long cutting engagement generates additional heat and force, so deep profiles need stable step-downs and clear chip evacuation. Adjust one parameter at a time after inspecting the first groove.
Material and Finish Guidance
Wood, plywood and MDF require effective dust removal and secure workholding. Acrylic, PVC and ABS need clean chips and controlled heat because rubbing can melt the cut edge. Foam and resin formulations vary, so a sample cut should confirm whether the selected settings produce a clean surface without tearing or melting.
Inspect both straight cutting edges for resin buildup, a chipped corner or uneven wear. Clean the tool using a suitable method and replace it when edge damage affects dimensional accuracy. Do not increase spindle speed to compensate for a worn cutter, as this can create additional heat without restoring the cutting geometry.
JEEFOO Supply from Guangzhou, China
JEEFOO manufactures and supplies solid carbide CNC router bits from Guangzhou, China, for distributors, workshops and industrial buyers.

Safe Operation and Tool Life
Confirm compatibility with the spindle and collet, stop the machine fully before tool changes and use eye protection and machine guards. Stable workholding, correct shank grip and gradual parameter changes help the 4×22 Two Straight Flute Router Bit deliver repeatable results and reduce the risk of breakage.
4×22 Two Straight Flute Router Bit FAQ
Can the full 22 mm cutting length be used in one pass?
The flute length provides capacity, but safe depth depends on material, rigidity, projection and chip evacuation. Multiple passes are often more reliable.
