* proven increases inproductivity, up to 33%  
* substantial improvemnts in tool life  
* the advantages of TiN coating at a fraction of the cost  
* versatility - equally suited to hand-held applications and first generation CNC machining.  
 
Features/Benefits:  
 
* Finish: Bright body to improve drilling in ductile materials. All surface are ground for precision  
* Substrate: Heat treatment process ensures consistently high quality.  
* Helix Angle: Standard helix angle with right hand spiral  
* Coating: Titanium Nitride (TiN) coating resists flank and crater wear, gives low friction, improvces thermal transfer of heat away from the tool, to allow increased cutting speeds and improved productivity.  
* Point Geometry: Self-centering 135 degree split point reduces thrust forces and improves chip form.
