A dome reamer drill bit functions to enlarge a borehole and it is designed with a drill portion and a reamer portion. The drill portion is formed by cutting edges at the end of a plurality of flutes, and the reamer portion includes a first relief formed on each flute surface disposed at a predetermined angle with respect to the flute surface to form a first reamer cutting edge. A second relief is formed contiguous with the first face on each reamer portion and is disposed at a second angle, less than the first angle with respect to the flute surface

Applications
• Underground mining
• Bench Drilling

Competitive Advantage

• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery

and heat treatment

Button carbide shape

Button shape	Application
	Hemispherical Buttons Universal button for all rock formations,best suited to hardest and very abrasive rock formations
	Parabolic button Excellent penetration rate,but only suited to medium hard and not so very abrasive rock formations
	Conical button For soft to medium rock hardness,more aggressive with faster penetration rates.
	Ballistic button Similar to Parabolic buttons,used for soft to medium hard and not so abrasive rock formations,excellent in penetration rate
