How to distinguish different cutting inserts


How to distinguish different cutting inserts
The identification of cutting inserts is mainly achieved by observing their model identification, shape features, material marking and applicable scenarios. The following are the specific methods:
Model Identification Analysis


Insert models are usually composed of multiple codes, for example, "TNMG160408N-GU" :
Shape code ‌ : for example, "T" represents an equilateral triangle and "N" represents non-directionality. ‌
 relief Angle code ‌ : For example, "N" indicates a 0° relief Angle (negative insert). ‌
Precision code ‌ : for example, "M" corresponds to a specific precision grade. ‌
slot hole code ‌ : For example, "G" indicates a perforated blade available on both sides. ‌
 cutting edge length code ‌ : "16" corresponds to a cutting edge length of 16.5mm. ‌
 Thickness code ‌ : "04" corresponds to a thickness of 4.76mm. ‌
The R code of the ‌ tool tip ‌ : "08" indicates a tool tip radius of 0.8mm. ‌
chip breaking groove code ‌ : "GU" is a general-purpose chip breaking groove for cutting. ‌
Shape corresponds to function
Different tip shapes are suitable for specific processing requirements: Drop Point: flexible cutting, suitable for peeling or multi-functional use. ‌
geometric tip (Tanto) ‌ : high penetration power, often used in tactical holders. ‌
Sheepsfoot ‌ : Straight blade design, suitable for cutting rather than piercing. ‌
placeholder0 Spear Point ‌ : symmetrical double blades, suitable for combat or tactical scenarios. ‌
Material and applicable scenarios
holder0 universal material blades ‌ : marked as P (steel), M (stainless steel), K (cast iron), suitable for a variety of materials. ‌
laceholder0 Specialized material blades ‌ : for instance, CBN blades (cubic boron nitride) are suitable for processing quenched steel, while PCD inserts (diamond) are ideal for mirror finishing of non-ferrous metals. ‌
Classification of irregular-shaped inserts
Non-standard shaped inserts (such as wavy round blades) are mostly used in special industries like printing and medical care, and the selection should be based on specific applications. ‌
