for increased durability and wear characteristics,  and YK 05 tungsten 
carbide as same grade as internationally well-known brand 
(2) Apply "hot (thermal) -insertion" processing procedure to 
insert the buttons as same as internationally well-known brand, 
(3) Entire CNC processing procedure ensure the quality consistency and reliable. 
(4) Military grade requirements of heat-treatment guarantee durability,
Specific heat treatment standards and special "stress relief" processes ensure 
consistent performance.
(5) Designed for maximum performance and hole cleaning ability and high penetration rate.
