Adriller Drill Bit

Adiller line of top hammer bits, also commonly referred to as button bits, have been specially designed to drill through almost any type of hard and abrasive rock formations.
These drill bits not only have a superior penetration rate compared to their competitors, but also a substantially longer service life .

Applications:

Bench Height: If a Bench Height Has Already Been Set Then This Will Need To Be Kept In Mind.

1. Type And Size Of The Explosives: Most Explosives Work Better When Used In Larger Blast Holes And When Buying Explosives In Bulk There Is Usually a Cost Advantage.
2. It Is Best To Select a Hammer Nearest The Maximum Operating Conditions Of The Compressor. The Higher The Hammer Operating Pressure, The Better The Performance. Altitude Correction Is Required For Applications Above 4,000ft (1,200m) To Assist In Calculating The Proper Compressor Output And Hammer Selection.

Feature Advantage:

1. When installing the down-the-hole drill bit, the drill bit should be placed gently into the drill bit of the down-hole hammer card. Do not force the collision to avoid damage to the drill bit or the card holder;
2. During the rock drilling process, it is necessary to ensure that the pressure of the down hole drilling rig is sufficient. If the hammer is interrupted, or the blast hole is not well discharged, the compressed air system of the down hole drilling rig should be inspected to ensure that there is no slag in the hole during the drilling process;
3. If metal objects are found to fall into the hole, they should be sucked out by magnets or taken out by other methods in time to avoid damage to the drill bit;
4. Pay attention to the size of the drill hole that has been drilled when replacing the drill bit. If the diameter of the drill bit is excessively worn, but the blast hole has not been drilled, the new drill bit cannot be replaced to avoid sticking. The work can be done using an old drill bit that has been used and has the same wear diameter;
