5-Flute D16*42*16*92 55*5T Unequal Helix & Variable Pitch End Mill for Stainless Steel

No.1601571794149
This high-performance 5-flute solid carbide end mill features an optimized unequal helix and variable flute pitch design, specially engineered for chatter-free machining of stainless steel (304, 316L) and other tough sticky alloys. Different from standard equal-flute cutters, its asymmetric structure breaks periodic cutting vibration, effectively eliminating chatter marks and ensuring ultra-smooth surface finish even under long overhang and weak machine rigidity conditions.
  • Vibration Suppression Design: Variable helix and unequal flute spacing disrupts resonant frequency, greatly improving machining stability for deep cavity milling, thin-wall parts and long-tool-overhang processing.
  • High Efficiency Cutting: 5-flute configuration increases cutting edges participation, delivering higher feed rate and superior metal removal rate compared with conventional 4-flute end mills, ideal for semi-finishing and finishing operations.
  • Premium Tool Body: Adopts ultra-fine grain carbide substrate with high rigidity and toughness, resisting chipping and abrasion during continuous heavy cutting.
  • Professional Heat-Resistant Coating: Equipped with high-performance AlCrN / AlTiN nano coating, featuring excellent high-temperature oxidation resistance, anti-sticking property and wear resistance, which effectively avoids built-up edge and extends tool service life in stainless steel machining.
  • Edge Protection: Precision edge honing and optional corner chamfer / radius design enhance impact resistance, prevent tip breakage and improve processing durability.

Product Overview ► 

Engineered for demanding metalworking applications, this 5-flute tungsten carbide end mill delivers exceptional wear resistance, thermal stability, and dimensional accuracy. With a core hardness of 55HRC and advanced TiCN coating, it maintains edge integrity across steel, stainless steel—reducing tool change frequency and maximizing uptime.

Designed for global OEM partners and precision machining workshops, every unit undergoes triple-stage factory inspection and is backed by full customization capability—from geometry adjustments to branding and packaging—ensuring seamless integration into your production workflow.

Core Advantages ► 

Ultra-Hard 55HRC Substrate

Sintered from premium-grade tungsten carbide with strict grain control—resists chipping, deformation, and micro-fracture under high feed rates and aggressive depths of cut.

TiCN Multilayer Coating

Titanium carbonitride coating provides superior oxidation resistance up to 600°C, reduces friction coefficient by 35%, and extends tool life by 2–3× vs. uncoated equivalents.

OEM-Ready Customization

Full engineering support for non-standard geometries (helix angle, flute count, corner radius), custom packaging, laser marking, and ISO-compliant documentation—all with no MOQ penalty.

Target Applications ► 

Automotive Powertrain

Cylinder head milling, transmission housing profiling, brake caliper machining

Aerospace Structural Parts

Perfect for high-precision machining of 304, 316L austenitic stainless steel, low-hardness alloy steel and general steel. Widely applied in side milling, square shoulder milling, contour milling, dynamic milling (HEM), thin-wall component processing and deep cavity finishing. Suitable for CNC machining centers and high-speed milling operations.

Medical Device Manufacturing

Stainless steel surgical instrument blanks, titanium orthopedic implants, precision enclosures

FAQ ► 常见问题
What materials can this end mill process effectively?

It is optimized for ferrous and non-ferrous metals including low-to-medium carbon steels (up to 35HRC), austenitic and martensitic stainless steels, gray and ductile cast irons, and wrought aluminum alloys (e.g., 6061, 7075). Not recommended for hardened tool steels (>45HRC) or superalloys without specialized geometry.

Do you offer technical support for cutting parameter selection?

Yes. Upon order confirmation, our application engineering team provides a tailored cutting data sheet—including recommended spindle speed (RPM), feed per tooth (mm/tooth), depth of cut (DOC), and coolant strategy—based on your specific machine, workpiece material, and operation type.

Can I request samples before placing a bulk order?

Sample requests are accepted for qualified industrial buyers. A nominal fee applies (fully credited against first bulk order), with lead time of 5–7 working days. Sample kits include 1–3 units with full spec sheet and test report.

How do you ensure consistency across production batches?

Every batch undergoes identical QC protocols: raw material certification, green density measurement, sintering profile logging, post-sintering hardness mapping, coating thickness verification (via SEM-EDS), and final geometry CMM audit. Batch certificates are provided with each shipment.
