High Wind Pressure Impact Drill Bit for Deep Hole Drilling

The lifespan of a drill bit depends on its material and technology. Anbit drill bits are made of the most efficient high-quality alloy steel.

Using high-quality forged steel, heat treatment, and shot peening to provide a durable and reliable balance of strength and toughness.

• Long lifespan of drill bits: Alloy steel materials have a longer lifespan than similar products
• High drilling efficiency: The drill teeth are wear-resistant, making the drill bit always sharp, thereby greatly improving the entry speed of the teeth
• Stable drilling speed: The drill bit breaks the rock by scraping and cutting
• Good spacing effect: The new diamond stone has strong wear resistance and good spacing performance, which enables efficient utilization of cutting teeth
• Wide applicability: Suitable for soft to medium hard formations such as carbonate rocks, limestone, Cretaceous rocks, clay rocks, siltstone, and sandstone (with drillability below level 9)

Generally made of high-strength alloy steel or hard alloy, it has good wear resistance and impact resistance, and can withstand the high-frequency impact force and rotational force generated by pneumatic drilling machines. There are two common structures: integral and assembled. The integral drill bit structure is simple, sturdy and durable, suitable for general drilling operations; Prefabricated drill bits can replace different cutting components, improving the service life and economy of the drill bit.

The shape and quantity of cutting edges vary according to different drilling requirements. Common types include cross shaped, one shaped, three bladed, and four bladed shapes. The cross shaped cutting edge can provide good stability and guidance during drilling, and is suitable for rocks and concrete of various hardness; The straight cutting edge has high cutting efficiency and is suitable for softer materials or shallow hole drilling; Three edge and four edge cutting edges can ensure cutting efficiency while better removing debris and improving drilling quality.

Used to connect the drill bit with the spindle of the pneumatic drilling rig, ensuring that the drill bit can accurately transmit impact and rotational forces. Common connection methods include threaded connections, bayonet connections, and tapered connections. The threaded connection method is simple and reliable, suitable for most pneumatic drilling rigs; The bayonet connection has the advantage of fast loading and unloading, which can improve work efficiency; Conical connections can provide a tighter fit and are suitable for high-precision drilling operations.

• See materials: Soft rock/coal seam → straight/cross shaped, medium hard rock → cross shaped/three bladed, hard rock → spherical tooth shaped
• Specification: The diameter matches the drilling requirements, and for deeper depths, a drill bit with a wider chip groove is selected
• Drilling rig: Select the material of the drill bit according to the power of the drilling rig (high power → hard alloy, low power → ordinary alloy)
• Check the environment: damp/corrosive → choose chrome plated/rust proof drill bit, explosion-proof scenario → choose spark free design

According to this logic, the adaptive drill bit can be quickly locked to avoid the problems of low efficiency and high cost caused by using the wrong tool.
