Rock Drill T45 Button Bit Drilling Tools Retrac Thread Button Bit

Product Description:

The thread drill bits are made by high quality alloy steel bar and famous brand tungsten carbide. The thread type includes R25, R28, R32, SR35, R38,T45,T51, ST58, GT60, ST68 and so on. The drill bit head diameters range from 32mm to 152mm. The buttons have different shapes,such as spherical,ballisticand conical. The face shapes include flat shape,drop-center shapes and engrave shapes,the body shapes have normal and retrac shapes. The threaded drill bit is widely used in tunnel construction, large scale mining, such as open-pit and underground copper,gold etc mining.

Products Feature:

• Raised center ensures center buttons hit the rock first, resulting in even better collaring and straighter holes.

• Optimized number and placement of flushing holes (depending on diameter size, either three or four), with equal distance between flushing grooves evenly distributing air flow and reducing wear on gauge buttons.

• No face slots ensures that the air is more evenly distributed around the bit, resulting in a more even wear. It also facilitates better clearing of cuttings in front of the bit and makes it possible to evenly place the buttons.

• The evenly-placed buttons enable the bit to cover the entire cutting area with just 90 degrees’ rotation. This means that there is no double breaking of the same rock or missed breaking, enabling more even wear of the buttons and resulting in increased button life. The even load distribution on all buttons also reduces the risk of button breakage.
