6.35×22 One Spiral Flute Bits for Clean Acrylic Cutting

6.35×22 One Spiral Flute Bits are designed for precise CNC routing, engraving and milling of acrylic and other non-ferrous materials. Manufactured by JEEFOO in Guangzhou, China, this solid tungsten carbide cutter combines a sharp single cutting edge with a polished spiral flute for fast chip removal, controlled heat and clean workpiece edges.

The 6.35×22 specification provides a practical balance of rigidity and reach for sign making, display fabrication, lettering, contour cutting, slotting and light pocketing. The solid carbide body is precision ground for dependable concentricity and repeatable cutting. When suitable feeds, spindle speed and workholding are used, the tool helps reduce melting, burrs and recutting of chips.

Materials and CNC applications

This 6.35×22 single-flute router bit is intended primarily for acrylic, PVC, ABS, aluminium composite panel, cork and compatible soft non-metal materials. It can support up milling, down milling, side milling, profiling, engraving and slot cutting. For aluminium or another demanding material, confirm machine rigidity, coolant or air-blast capability and conservative parameters before production.

solid carbide solid tungsten carbide for rigidity, precision and useful tool life.
Polished single spiral flute for efficient chip evacuation and reduced heat.
Sharp cutting edge for smooth acrylic profiles, grooves and engraved details.
Suitable for CNC routers and compatible milling or engraving machines.

Recommended setup and cutting practice

Install the cutter in a clean, correctly sized collet and keep tool overhang as short as the job allows. Secure the workpiece firmly and check that the spindle, collet and tool are free from excessive runout. Start with conservative cutting parameters based on the machine, material thickness and tool engagement, then adjust after inspecting chip formation and edge quality.

A steady feed is important when machining acrylic. Feeding too slowly can cause rubbing and heat, while an aggressive cut may overload a small spindle or produce chatter. Use air blast or vacuum extraction where appropriate to clear chips. Test on scrap material before production, especially when changing acrylic grade, sheet thickness, flute engagement or workholding.

Frequently Asked Questions

What are 6.35×22 One Spiral Flute Bits used for?

They are used for CNC routing, engraving, profiling, slots and light pockets in acrylic, PVC, ABS, aluminium composite panel and compatible soft materials.

Why is a single flute suitable for acrylic?

A single flute creates a large chip space. This helps chips leave the cutting area, limits recutting and supports heat control and cleaner acrylic edges.
