Negative Rake:
Negative rake tools should be selected whenever work-piece and machine tool stiffness and rigidity allow. Negative rake, because of its strength, offers greater advantage during roughing, interrupted, scaly, and hard-spot cuts. Negative rake also offers more cutting edges for economy and often eliminates the need for a chip breaker. Negative rakes are recommended on insert grades which do not possess good toughness (low transverse rupture strength)
Negative rake is not, however, with- out some disadvantages. Negative rake requires more horsepower and maximum machine rigidity. It is more difficult to achieve good surface finishes with negative rake. Negative rake forces the chip into the work-piece, generates more heat into the tool and work-piece, and is generally limited to boring on larger diameters because of chip jamming.

负耙：
负耙工具，应选择工作时，工件和机床的刚度和刚度允许。负耙，因为它的实力，提供了更大的优势，在粗，中断，鳞片，硬现货削减。负耙还提供了更多的前沿，为经济和消除，往往需要一个芯片断路器。负面rakes建议对插入的职系不具备较好的韧性（低横向抗弯强度）
负耙是没有，不过，随出一些弊端。负耙需要更多的马力和最高机刚度。这是更难以实现良好的表面饰面负耙。负耙势力芯片到工作片，会产生更多的热量转化的工具和工作片，而且通常只限于沉闷，对较大的直径，因为芯片的干扰。
