Features Processing application: good toughness and hardness. Pressure bars for semi-precision and fine machining operations; knife for machining steel. Drill rod model: Indexable drill bar models include S12M-SDUCR07; SDJCR1212H07; SDJCL1212H07; SDNCN1212H07. Hard alloy blade: There are 10 pieces DCMT070204 carbide inserts that can be easily replaced. You can do the replacement of the blade with just one wrench. Precision and efficiency: can reduce the cost of grinding cutting tools and improve cutting efficiency. The fine impact resistance at low temperature has improved the surface gloss of the cutting part. High hardness and durability: good grip, strong impact resistance, obvious speed advantages and large quantities when cutting and processing. Easy to carry and use. Package List
