Spiral Hemispherical Burr, 0.25 mm Radius, 4 mm Diameter

【Rounded Geometry】The R0.25 rounded tip geometry of the ball end mill prevents tool chipping, allowing for smooth contour finishing and reducing manual deburring time on complex 3D surfaces.
【Chip Evacuation】The single-spiral chip evacuation creates a wide groove for rapid waste removal, preventing heat buildup and clogging during deep grooving and vertical plunge cutting.
【Hard Composite Cutting Edge】The tungsten steel hard composite cutting edge maintains sharpness and dimensional accuracy when machining hardened steels, cast iron, and titanium alloys.
【Multi-Angle Taper Cutter】The taper profile of this taper cutter provides clearance for machining draft angles, mold cavities, and Undercuts in the manufacture of injection molds and dies.
【Compatible Round Shank】The 4mm straight round shank securely fits into collets, hydraulic tool holders, and retraction systems, minimizing runout for high-speed applications.
