4×22 Down Cut Two Spiral Flute Bits for Clean Top Edges
The 4×22 Down Cut Two Spiral Flute Bits are designed for CNC routing where a clean top surface and controlled chip direction are important. The left-hand spiral pushes chips downward, helping reduce lifting and edge breakout on MDF, plywood, laminated board, acrylic, PVC and similar sheet materials.
Key specifications
- Cutting diameter: 4 mm
- Cutting length: 22 mm
- Geometry: two-flute down-cut spiral
- Material: wear-resistant solid carbide
- Typical equipment: CNC routers and engraving machines
Why choose a down-cut spiral bit?
A down-cut tool directs cutting pressure toward the work surface. This helps the 4×22 Down Cut Two Spiral Flute Bits produce a smooth upper edge on laminated panels and thin sheets. For through cuts, use a spoilboard and select a suitable feed rate so chips can clear without excessive heat.
Recommended applications
- Lettering and sign making in MDF or acrylic
- Profile cutting of plywood and laminated board
- Grooving in PVC, PP, PE and other plastics
- Fine CNC engraving that requires a clean visible surface
Machining guidance
Confirm the collet is clean, grip the shank securely and keep tool overhang as short as practical. Start with conservative cutting parameters, then adjust spindle speed, feed and depth per pass according to material rigidity and machine condition. Chip evacuation and dust extraction improve finish consistency and tool life.
