**SPECIAL FEATURES :-I Designed particular for the drilling on various steel material used on theconstruction of high building, bridge, ship building and rails etc..II For precision fabrication process may use borer on precise milling machinesIII Improved carbide teeth to prolong its life span.IV Three-part split bits to ensure smooth removal of dust in order to preventdeterioration in cutting efficiency due to the jamming with dust.V 3 channels and fixing holes for easy loading and unloading of cutting bladesin one touch with 1 platform for fixation of screws to keep out rotation.
Characteristic :It is one of the W-Ho HSS grade, the high hardness red hardness and wearing resistance are all better thanM2, this kind of steel is suitable for producing in high ability cutting tool, such as hob, knife and milling cutter.
