UEX Series

UEX Series End Mills for Mold Steel: From roughing to finishing, one-stop solution.

2-flute slotting with large chip space, 4-flute sidewall mirror-like finish, ball nose for high-precision curved surfaces, corner radius for heavy loads without chipping, long neck for stable deep cavity machining—UEX Series, the professional family for mold steel machining.

From H13 to SKD11, from HRC50 to HRC60, no matter which mold steel, UEX always has one for you.

Core Pain Points of Mold Steel Machining and UEX Solutions

Machining Pain Point	Technical Difficulty	UEX Solution	Applicable Model
Slotting	Difficult chip evacuation, chip clogging leads to tool burning	Double-core design, small core diameter at front ensures chip evacuation	2-Flute Square End Mill, 2-Flute Long Neck End Mill
Sidewall Finishing	Vibration marks, tool deflection, poor surface finish	4-flute high-rigidity structure, unequal division design breaks resonance	4-Flute Square End Mill, 4-Flute Corner Radius End Mill
Curved Surface Machining	Fast ball nose wear, center point extrusion	Precision-ground ball nose profile, optimized center edge design	2-Flute Ball Nose End Mill, 4-Flute Ball Nose End Mill
Heavy Depth Heavy Load	Edge chipping, short tool life	Corner radius design, +40% edge strength	Corner Radius End Mill, High-Performance Corner Radius End Mill
Deep Cavity Machining	Insufficient rigidity for long overhang, obvious vibration marks	Long neck clearance design + double-core structure, enhanced rigidity	All Long Neck Series models
