Use super-hard high-speed steel, durableTo optimize the cutting edge through the center of the design, based on the machined,workpiece more smoothHas a very high wear resistance and strength, exclusively for high-speed cutting of high,hardness cutter versatile applicationsCapable of 55 degrees of heat directly following a high speed roughing to fine machining,reducing the number of tool changes ahead of the machine utilization rate, save when makingprocess to the cutting surface milling / short side milling based.Material: High-speed steelFlute quantity: 4 flutescolor:SilverSize1.5mm: Cutting Diameter:1.5mm; Shank Diameter:6mm;Overall Length:51mm;2mm: Cutting Diameter:2mm; Shank Diameter:6mm;Overall Length:51mm;2.5mm: Cutting Diameter:2.5mm, Shank Diameter:6mm;Overall Length:52mm;3mm: Cutting Diameter:3mm; Shank Diameter:6mm;Overall Length:52mm;4mm: Cutting Diameter:6mm; Shank Diameter:6mm;Overall Length:55mm;5mm: Cutting Diameter:5mm; Shank Diameter:6mm;Overall Length:57mm;6mm: Cutting Diameter:6mm; Shank Diameter:8mm;Overall Length:60mm;Suitable For: Carbon steel, tool steel, alloy steel, tool steel, quenched and temperedsteel, cast iron, stainless steel, heat-treated steelNoteBefore using this tool, please measurement tool deflection, tool deflection accuracyexceeds 0.01MM, please correct before cutting.The shorter the length of the tool projecting chuck of the better, if the amount of thetool extends the projected long, please cut their own speed, feed rate or cutting the amount.When cutting, if the abnormal vibration or sound, cut spindle speed and depth of cutto improve the situation so far.Cooling the steel material to a spray or jet is the best way to apply, so that high aluminumtitanium play the best results. Stainless steel, titanium alloy or heat resistant alloy recommendthe use of non-water-soluble cutting fluid.Packing Included7 x 4 Flute End Mill CutterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
