30mm Diamond Bit For Angle Grinder

Item No:MP60445

 

 

30mm diamond bit for angle grinder

Diameter: 30mm

Thread size: M14

Rotation: 12200/minute

Material: #45 carbon steel "

 

 

1. Core features and adaptation scenarios

 

1. Cutting principle of diamond bits

Diamond particles (or sintered diamond layers) are embedded on the surface of the drill bit, and the ultra-hard characteristics of diamond (hardness of Damo 10) are utilized to achieve cutting or drilling of hard materials through high-speed rotating friction.

45 #carbon steel substrate: provides structural strength to ensure that the drill bit is not easily deformed when rotating at high speed. The M14 thread is suitable for most angle mills (the interface specifications of the angle mill need to be confirmed).

 

2. Key parameter matching

30mm diameter: Suitable for drilling holes with a diameter of 30mm, often used for operations with larger diameters;

12200 rpm: High-speed rotation and diamond particles can efficiently cut hard materials and avoid excessive wear of diamonds due to insufficient speed.

 

 

2. Specific uses

1. Construction and decoration engineering

Concrete/brick wall drilling: Drill 30mm holes in concrete walls, red bricks/hollow bricks for installation of water pipes, gas pipes, ventilation pipes, expansion bolts, etc. For example:

When renovating the kitchen and bathroom, drill through the wall to arrange drainage pipes;

When installing the air conditioner external unit bracket, drill holes in the concrete wall to fix the expansion screws.

 

Stone holes: Drill holes in marble, granite, ceramic tiles and other stone materials for installing faucets, bathroom pendants, stone decorative parts, etc. Note: Water needs to be added to cool down when drilling to avoid overheating and failure of diamonds.

 

2. Industry and Manufacturing

Metal plate drilling: A 45 #carbon steel substrate is matched with diamond particles. A 30mm hole can be drilled in thin metal plates (such as steel plates and aluminum plates) for assembly of mechanical parts, equipment piping connections, etc.

 

Special material processing: suitable for drilling hard and brittle materials such as ceramics, glass (special glass drill accessories are required), refractory materials, etc., such as:

Openings before installation of ceramic sanitary products;

Pipe perforation of industrial kiln refractory bricks.

 

3. Repair and renovation scenarios

Enlarging or correcting old holes: When it is necessary to expand the original small hole (such as the diameter is less than 30mm), you can use this drill to directly drill the hole to avoid the cumbersome replacement of tools.

 

Emergency drilling operations: In outdoor construction or emergency maintenance, the angle grinder can be used with this drill bit to quickly drill holes in hard materials to solve the need for temporary pipeline and cable layout.

 

 

3. Precautions for use (extended supplements to ensure safety and efficiency)

installation and fixation

Confirm that the angle grinder interface is M14, tighten the threads during installation to avoid the drill bit becoming loose and falling off during high-speed rotation;

Before operation, check the drill bit for cracks and diamond layer falling off to ensure safety.

 

operation specifications

Wear goggles, dust masks, and gloves to prevent debris splashing and dust inhalation;

Keep the angle grinder stable and perpendicular to the working surface during drilling to avoid oblique wear or sticking of the bit due to oblique force.

 

Cooling and maintenance

When drilling concrete, stone and other materials, it is recommended to continuously add water to cool it (by spraying or dipping in water) to prevent overheating and wear of the diamond;

Clean up debris on the surface of the drill bit after operation to avoid impurities accumulating between diamond grains and affecting the next use.

 

 

4. Differences from other drill bits

Compared with ordinary carbon steel bits: Diamond bits are suitable for hard and brittle materials (such as concrete and stone), while ordinary bits are only suitable for soft materials such as wood and metal;

 

Compared with ceramic drills: 30mm large diameter diamond drills are more suitable for large-diameter operations. Ceramic drills are usually used for drilling glass and ceramic tiles with small diameters (such as 6-12mm).
