Specification Brand : CNC TEC Tool BulletPoint1 : General Usage : Applicable with copper, copper alloys, cast iron, steels, carbon steels, alloy steels, pre-hardened steels, hardened steels, and stainless steel materials.Best use for materials HRC less than 50. BulletPoint2 : AlTiCrN Coating : Aluminum Titanium Chromium Nitride (AlTiCrN)offering better heat resistance than TiAlN, TiN or TiCN coatings. It is able to provide high wear resistance, lubricity, exceptional oxidation resistance, extreme hardness, and excellent abrasive wear resistance. It has higher re liability in Dry operations, heat resistance, hard machining, and the resistance can be reduced. BulletPoint3 : 4 Flute Cutter: It has uniqe geometry and strong cutting edge. 4 flute is great for speedy cutting. Ideal for planar, step, groove, forming surface while the 45 Degree Helix design can perform smooth surface finish, better chip removal control than those with lower helix degree. BulletPoint4 : Cutting Diameter Tolerance : high accuracy with an error of -0.02mm BulletPoint5 : ✅ DEDICATED SUPPORT - Please don't hesitate to contact us on Amazon if you need the Cutting Condition Data. We want to ensure you receive the best product that meets your requirements.
