About this item

  • Size - Cutting diameter: 7mm / 9/32"; cutting flute length: 20mm / 25/32"; shank diameter: 8mm / 5/16"; overall length: 60mm / 2-3/8"; cutting hardness: HRC55; number of flutes: 4 flutes; end cut type: square end
  • Material - Micro grain carbide end mills offer high hardness, wear resistance, enhanced rigidity and excellent heat resistance. Features sharp, precision ground cutting edges for clean, precise cuts, resulting in accurate machining and excellent surface finish on your workpiece.
  • Features - AlTiN (aluminum titanium nitride) coating increases hardness and wear resistance, improves lubricity, enhances chip evacuation, and can withstand higher cutting speeds and feeds, providing better performance than TiAlN, TiN or TiCN coatings.
  • Applications - Suitable for alloy steel, stainless steel, carbon steel, pre-hardened steel, hardened steel, cast iron, non-ferrous metals, and plastics. Square end mills are used to create slots (keyways or internal grooves), straight or square edge features, flat smooth surfaces, holes or for roughing, finishing and side milling operations.
  • Note - Ensure that the square end mill is securely held in the tool holder or collet. Maintain stable cutting conditions by adjusting the feed rate and depth of cut appropriately. Use proper lubrication and cooling methods when machining.

Applications

The cnc end mill is suitable for alloy steel, stainless steel, carbon steel, pre-hardened steel, hardened steel, cast iron, non-ferrous metals, and plastics (cutting hardness below HRC55 materials).

Square end mills are used to create slots (keyways or internal grooves), straight or square edge features, flat smooth surfaces, holes or for roughing, finishing and side milling operations.

Use proper lubrication and cooling methods when machining. Using coolant or a suitable cutting fluid can help dissipate heat and improve chip evacuation.

I used this end mill for an aluminum project that I needed to knock out without the use of coolant. The coating really helped mill not to load up while using with trim router since feed and speed can really vary doing it manually. The quarter inch shaft fit perfect in collet and runout seemed to be true, but no real way of checking on portable router. No vibration was detected while in use and chips were mostly uniform and not discolored even without coolant. End mill seemed to cut just as well at end of project as the start and upon closer inspection of cutting surface showed no chipping or dulled edges. I would imagine with coolant you could really make the chips fly without worry. Overall a great end mill for asking price. This vendor will definitely stay on my go to list for cutting tools.

Perfect for jewelry work that I do, very material removal rate for its size, cutting edge has held up well so far too. Probably be ideal for other small-diameter projects like PCB work too.
