Widin Carbide End Mill - 4 Flute Square Edge Long Neck 1.5mm x 18mm

The Widin Carbide End Mill with a 4-flute square-edge and a long neck is a precision cutting tool built for challenging materials. Designed to machine high-hardened workpieces up to HRc70, it delivers reliable performance in a compact 1.5 mm diameter with an 18 mm reach, making it a practical choice for tight pockets, fine slots, and intricate contours. This tool is ideal for engineers, machinists, hobbyists, and shop floors that need consistent results on hard metals.

Its distinctive long-neck design provides extended reach to access features with draft angles, helping you maintain control and avoid interference on complex parts. The neck length is engineered to accommodate longer interference lengths required for different draft angles, so you can mill deeper features without sacrificing accuracy. Coupled with a newly developed raw material and advanced coating (ZSLNS20), the end mill supports dry cutting and high-speed cutting, delivering improved heat resistance, wear resistance, and overall performance for demanding cycles.

• Long-neck geometry for difficult draft angles: Extended reach ensures you can mill deep or angled features without risking tool interference, improving accuracy on complex workpieces.
• Dry and high-speed cutting with advanced coating: Enhanced heat and wear resistance enable faster cutting and longer tool life, reducing cycle times and downtime.
• Four-flute square-edge design for clean finishes: Sturdy, precise geometry provides efficient material removal and consistently smooth surface finishes on hard materials.

The Widin end mill is a dependable choice for precise, high-quality milling on hardened alloys. It supports efficient machining workflows, helps you achieve reliable finishes, and delivers predictable performance across challenging applications—from slots and pockets to contouring—and is well-suited for both production environments and detailed repair work.
