RUKO KEB-HM-Weldon-12.0mm Solid Carbide End Mill

Precision milling in tough materials demands a cutter that resists wear and delivers clean, accurate results. The RUKO KEB-HM-Weldon-12.0mm solid carbide end mill is built for exactly that: a 3-flute, center-cutting tool with a Weldon shank for secure clamping and reliable material removal in steel, cast iron, non-ferrous metals, and plastics.

Who is it for

Machinists, toolmakers, and production engineers who need a dependable end mill for slotting, profiling, and plunging operations. Its solid carbide construction handles materials up to 55 HRC, making it suitable for both general-purpose and demanding milling tasks.

Main features

• Solid carbide (HM) body for high wear resistance and long tool life
• Weldon shank (DIN 1835 B) with h6 tolerance for secure, vibration-free clamping
• 3-flute geometry with 30° helix angle for efficient chip evacuation and smooth cutting
• Center-cutting design enables plunge milling and ramping
• Uncoated sharp cutting edges for low cutting forces and excellent surface finish
• Manufactured to DIN 844 K (short series) for compact, rigid performance

Tips

For best results, use rigid toolholders and ensure proper runout control. Apply external coolant or air blast to clear chips from the cutting zone, especially when slotting deep cavities. Reduce cutting parameters when machining materials near the hardness limit to preserve edge sharpness.
