Our Flat End Mill series delivers clean, flat-bottom finishes for slotting, shoulder milling, ramping, and pocketing. Tools are produced in Changzhou, Jiangsu on Swiss and German multi-axis grinding centers. This manufacturing setup yields sharp edges, consistent geometry, and stable performance in CNC machining of steels, stainless steels, cast iron, and non-ferrous materials. Solid carbide substrates and controlled edge prep help achieve reliable surface quality and repeatable size control.
Product Range and Core Specifications
Standard square end mills: Metric and inch sizes with precision-ground shanks (e.g., h6) for stable clamping. Tight diameter tolerances support repeatable accuracy.
2-Flute: Large flute space for chip evacuation and high feed in softer materials; ideal for aluminum alloys, plastics, and wood-based composites.
3-Flute: Balanced chip flow and higher metal removal for non-ferrous and stainless; suitable for high-speed side milling.
4-Flute: General-purpose option for steels; good edge strength and smooth finishes with reduced chatter.
6-Flute / Variable pitch: Efficient finishing on hardened steel and stainless; vibration control for thin-walled parts and longer overhangs.
Aluminum series: Polished flutes, high rake geometries, and DLC/TiB2 coatings for burr-free edges and fast chip evacuation in aluminum and copper alloys.
Micro and long-reach: Sub-millimeter diameters for precision features; reduced-neck options access deep cavities and complex molds while maintaining rigidity.
Options: Standard and extended lengths, corner chamfer or radius to strengthen edges, and shank choices to match common holders.
Materials, Coatings, and Geometry
Carbide substrates: Sub-micron grain grades balance hardness and toughness, resisting wear and micro-chipping in steels and high-temperature alloys.
Coatings: TiAlN/AlTiN for hot hardness in steels and hardened materials; TiB2/DLC to minimize built-up edge in aluminum; uncoated sharp edges for plastics and soft materials.
Geometry: Helix angles from 35–55°, variable helix for chatter reduction, and optimized rake/relief for stable cutting forces.
Applications and Operations
Steels and stainless: Use 4–6 flutes with TiAlN/AlTiN; expect stable chip control and consistent wall quality.
Cast iron and hardened materials: Variable pitch and high-hardness coatings help suppress vibration and resist abrasive wear; keep overhang short.
Aluminum, copper, plastics, wood: Polished 2–3 flute tools with TiB2/DLC reduce built-up edge and improve chip flow for high-speed slotting and clean profiles.
Operations: Precise slots and square shoulders, ramping into pockets without pre-drilling, and side milling with minimal chatter.
Selection Guide and Starting Parameters
Flute count: 2–3 for non-ferrous and slotting; 4–6 for steels and finishing.
Helix: Higher helix improves finishes; variable helix lowers vibration.
Reach: Keep overhang minimal; use reduced neck for deep pockets.
Starting ranges:
Aluminum: High surface speed, higher feed per tooth; sharp or TiB2/DLC.
Steel: Moderate to high speed with TiAlN/AlTiN; climb milling preferred.
Stainless: Lower speed, higher coolant flow; 3–5 flutes recommended.
Hardened: Lower feed, rigid setup, variable pitch geometry.
Quality, Production, and Traceability
Advanced CNC grinding centers (TTB, DECKEL S22/SRO, WALTER HELITRONIC, ANCA) provide sub-micron accuracy and thermal stability for consistent edges at scale. Metrology and presetting with ZOLLER, PG1000, PARLEC, and EOUER verify geometry, runout, and edge quality. ISO9001 (2023–2026) and SGS-backed processes with lot tracking and documented inspections support repeat runs and regulated applications.
Customization and Engineering Support
We engineer non-standard square end mills per drawing or sample, matching geometry, carbide grade, and coating to your machine and material. Process-ready tooling packages align holders and CNC parameters. Automated multi-axis grinding and in-line inspection enable pilot runs through volume production with reliable lead times.
