BEYOND Spiral Groove Thread Milling Cutter — Full-Thread (Internal Thread)
Brand: BEYOND
High-precision spiral groove full-thread milling cutters for internal metric threads. Designed for CNC thread milling of M3–M24 internal threads with excellent chip evacuation and tool life.
- Full-thread spiral groove design: consistent, full-flank thread milling
- Multi-flute carbide construction for exceptional hardness and wear resistance
- Optimized helix and flute geometry for efficient chip evacuation in blind and through threads
- Works on steels, stainless steels, aluminum and alloyed materials
- Available in metric sizes M3 → M24 (standard ISO pitches)
- Compatible with standard tool holders for precision CNC milling
Product Overview
The BEYOND Spiral Groove Thread Milling Cutter (Full-Thread) is engineered for reliable, high-accuracy internal thread production on modern CNC machining centers. Its spiral groove full-thread geometry provides continuous thread engagement and improved surface finish for metric threads M3–M24. Ideal for prototyping and production when thread accuracy and repeatability are required.
Applications
- Internal thread milling on CNC machining centers (blind and through holes)
- High-precision components: fixtures, hydraulic components, aerospace & automotive parts
- Materials: low-carbon & alloyed steels, stainless steels, aluminum alloys, pre-hardened steels (with proper feeds)
Why choose BEYOND thread mills?
- Precision – engineered for tight tolerances and consistent flank form.
- Durability – premium carbide substrate with wear-resistant geometry.
- Chip management – spiral groove design reduces chip clogging in blind threads.
- Flexible – single tool can cover many thread sizes (model dependent).

Recommended Starting Cutting Conditions — Example Values
Use these as starting points. Always verify with a test cut and adapt based on machine rigidity, clamping, coolant, and material condition.
| Thread Size | Spindle Speed (rpm) — Steel (≈200–500 HB) | Feed per Revolution (mm/rev) | Feed (mm/min) | Coolant |
|---|---|---|---|---|
| M3 | 10,000–20,000 | 0.02–0.05 | 200–1000 | Flood or MQL |
| M5 | 8,000–15,000 | 0.03–0.07 | 240–1050 | Flood or MQL |
| M8 | 5,000–12,000 | 0.04–0.09 | 300–1080 | Flood |
| M12 | 3,000–8,000 | 0.06–0.12 | 360–960 | Flood |
| M16 | 2,500–6,000 | 0.08–0.15 | 600–900 | Flood |
| M24 | 1,500–3,500 | 0.10–0.20 | 150–700 | Flood |
Advice: For stainless steels and pre-hardened materials, reduce speed 20–50% and reduce feed slightly. For aluminum increase spindle speed and use high feed to avoid built-up edge. Use light axial passes and step-down as appropriate for blind holes.
