HHIP 8002-5727 4 Flute 3/8 X 3/8 X 1-1/2 X 3-1/4 M42 Cobalt Coarse Roughing End Mill

HHIP 8002-5727 4 Flute 3/8 X 3/8 X 1-1/2 X 3-1/4 M42 Cobalt Coarse Roughing End Mill

• Secure Weldon Shank - Features a 3/8" shank with a flat surface to ensure a firm and stable fit in tool holders. Tooth Geometry - Roughing end mills have serrated cutting edges, known as chip breakers, which help in breaking chips effectively. Coarse Pitch - Coarse threads require fewer rotations to achieve full engagement, speeding up installation and removal.
• Material Removal Rate - Roughing end mills can remove over 90% of material quickly, enhancing efficiency. Reduced Cutting Forces - The serrated design disperses cutting forces, lowering the risk of tool breakage. Center Cut Capability - High-speed steel single-end mills are designed for plunge cutting, slotting, ramping, pocketing and general milling.
• Wear Resistance - M42 8% Cobalt provides superior red hardness and excellent wear resistance (68–70 HRC), making it ideal for heavy-duty applications, high cutting speeds, and tough-to-machine materials like stainless steel, titanium, Inconel, alloys and tool steels.
• Chip Resistance - M42's design provides excellent chip resistance, reducing the likelihood of tool failure during operation. Ground from Solid - Ground end mills are manufactured to tighter tolerances, ensuring high accuracy in machining processes.
• Used by CNC machinists (roughing operations), production machine shops, aerospace, heavy industry (hard alloys), tool & die makers, job shops removing large stock quickly and maintenance & repair teams working on tough materials. Cutting diameter is 1/4". Shank diameter is 3/8". Cutting length is 5/8". Overall length is 2-7/16".
