16mm Carbide Bull Nose End Mill 4-Flute - R0.5-R2.0 Corner Radius End Mills

Introduction:

This 16mm 4-flute carbide bull nose end mill features a precision-ground corner radius (R0.5-R2.0) for superior performance in contour milling, 3D profiling, and slotting applications. Designed for CNC machining centers, it combines the strength of micro-grain tungsten carbide with optimized flute geometry to deliver smooth finishes and extended tool life in steel, aluminum, and composite materials.

Features:

✔ High-Performance Carbide Substrate

• Grade K30/K40 micro-grain carbide for wear resistance in abrasive materials

• Sub-micron grain structure ensures edge retention at high RPM

✔ 4-Flute Spiral Design

• 30°-45° helix angle (selectable) for efficient chip evacuation

• Balanced flute geometry reduces vibration in deep-pocket machining

✔ Bull Nose Radius Edge

• R0.5-R2.0 corner radius options (customizable)

• Blends sharp corner precision with the durability of rounded edges

• Ideal for mold cavities and organic 3D shapes

✔ Advanced Coating Options

• Uncoated: Best for aluminum/copper (prevents material adhesion)

• AlTiN Coated: For hardened steels (HRC 50+) and high-temperature alloys

✔ Rigid Shank & Tolerance

• h6 tolerance shank (DIN 6535) for minimal runout

• Weldon flat or cylindrical shank options

Advantages Over Competitors
