Hard alloy drill bits are equipment used in drilling engineering. Hard alloy drill bits break rocks by relying on the impact load generated by the drilling pressure and their own rotation. During rock drilling, the drill bit undergoes high-frequency impact loads and is subjected to various combined stresses such as torsion, bending, tension, and compression. It also endures wear and corrosion from working media such as rock, rock powder, and mine water in a high-speed rotational collision environment. The toothed drill bits used domestically and internationally are mostly three-toothed drill bits. The characteristics of this type of drill bit are: the distribution range of axial pressure and impact load is large and uniform, and it can fully utilize the effective space, making the drilling stable. The size and shape of the hard alloy teeth used in the toothed drill bit must be suitable for the characteristics of the rock, requiring good wear resistance, high strength, and being less prone to cracking and breaking. The hard alloy teeth used in toothed drill bits mainly include: spherical teeth, conical spherical teeth, wedge-shaped teeth, edge wedge teeth, and flat top teeth for the back of the wheel and the claw tip. Generally, toothed drill bits for drilling extremely hard rock layers mainly use spherical teeth, with a drilling pressure of 892~1339 MPa and a rotational speed of 50~80 r/min; toothed drill bits for drilling hard and medium-hard rock layers use conical spherical teeth, with a drilling pressure of 714~1071 MPa and a rotational speed of 60~100 r/min; toothed drill bits for drilling soft and medium-soft rock layers use wedge-shaped teeth or edge wedge teeth, with a drilling pressure of 535~803 MPa and a rotational speed of 80~120 r/min.  Hard alloy drills are classified into four basic types: integral hard alloy drills, hard alloy replaceable insert drills, welded hard alloy drills, and replaceable hard alloy tooth crown drills. Each type of drill has its own advantages suitable for specific processing conditions.  Usage and Features: 1. Capable of drilling through complex materials, with the option to select a higher cutting speed. 2. Utilizes high-performance alloy blades specially designed for alloy drills, effectively reducing chip breakage and maintaining excellent wear resistance. 3. Multiple layers of geometric cutting edges enhance drainage performance and maintain low cutting resistance. 4. Besides the common right-angle handle, various handle types are available, suitable for various drilling machines and drilling presses.   Deep Hole Drill Tips Solid Carbide Drill Heads Full Carbide Deep Hole Drills

Drill guns, BTA systems and jet suction drills are three mainstream deep hole processing technologies. They solve the problems of chip removal and cooling that ordinary drills cannot handle. However, their implementation principles and application scopes are significantly different. 1. Gun Drill System - External Chip Removal Deep Hole Processing Working Principle: The gun drill is a single-piece carbide tool that resembles a pistol bullet. High-pressure cutting fluid (approximately 2-10 MPa) is forcibly injected through the hollow channel inside the drill rod to the cutting edge at the front end of the drill head for cooling and lubrication. Then, the chips are expelled along the annular space between the external V-shaped chip-receiving groove of the drill rod and the already machined hole wall in the reverse direction. "Internal Inlet and External Outlet" is its core feature. Advantages: High precision: The processed hole dimensions can reach IT7-IT9 grade, with good straightness and surface roughness of Ra value ranging from 0.8 to 3.2 μm. Wide hole diameter range: It is highly suitable for processing small-diameter deep holes. The typical processing range is φ1.5mm to φ40mm, with a depth-to-diameter ratio of up to 100:1. Good surface quality: Single-edge cutting, with asymmetric force but balanced by the guide strip, the processing process is smooth. Disadvantages: Limited chip discharge channel: Chips must be discharged from the limited V-shaped groove on the drill pipe's exterior. Therefore, the chip-breaking requirement is extremely high and it is not suitable for processing ductile materials that tend to form long ribbon-shaped chips. Lower efficiency: Single-edge cutting and limited chip discharge capacity result in a relatively slow feed speed. Application scenarios: Widely used in deep hole processing of medium and small diameters, high precision, and high output, such as spray oil holes in oil pump and oil nozzle, flow channels in hydraulic valve blocks, medical devices, mold cooling water holes, etc. II. BTA System - Internal Chip Discharge Deep Hole Processing Working principle: The BTA system consists of a drill bit, drill pipe, and a dedicated BTA drill sleeve (oil distributor). High-pressure cutting fluid (approximately 1-5 MPa) is injected through the drill sleeve into the annular space between the drill pipe and the hole wall, flows towards the drill bit head, cools and lubricates, and then carries the chips out from the huge hollow channel inside the drill pipe in the reverse direction. "External advance and internal discharge" is its core feature. Advantages: Chipping is smooth: The inner hole of the drill rod is the only channel for chip removal, with ample space, capable of handling various forms of chips, especially suitable for processing tough materials such as steel and alloy steel. High efficiency: It mostly uses multi-edge cutting and has smooth chip removal, allowing for larger feed rates, resulting in high material removal rate. Wide bore diameter range: It is mainly used for the processing of medium and large deep holes with a diameter of φ12mm or above. The depth-to-diameter ratio is usually less than 100. Disadvantages: Complex system: Special BTA drill holders and sealing devices are required, and the workpiece structure needs to allow for the installation of drill holders. High initial investment: The cost of tools and auxiliary equipment is relatively high. Applicable scenarios: Efficient rough machining and semi-finishing of medium and large deep holes in large shaft parts, gun barrels, energy equipment (such as boiler tube plates), hydraulic cylinder tubes, etc. III. Jet Drilling System - Internal Chip Removal Improvement Working principle: The jet drilling is an improved version of BTA, also using internal chip removal. Its uniqueness lies in the use of a double-layer pipe structure for the drill rod. A part of the high-pressure cutting fluid, like the BTA system, is pressed into the cutting zone through the gap between the inner and outer pipes; the other part is discharged through multiple backward-sloping nozzles on the inner pipe, utilizing the Venturi effect to generate suction. The "push-suction combination" works together to significantly improve chip removal efficiency and reliability, and the required oil pressure is lower than that of the BTA system. Advantages: Best chip removal effect: The combined push and suction action ensures thorough and reliable chip removal, especially suitable for processing extremely deep holes and materials with high processing difficulty. Lower oil pressure requirement: Compared to the pure BTA system, the oil pressure required to achieve the same effect is lower, and the system is more energy-efficient. Disadvantages: Most complex structure: The double-layer pipe design makes the manufacturing of the drill rod complex, with the highest cost, and the effective inner diameter of the inner hole is relatively reduced. Slightly poorer rigidity: The double-layer pipe structure may weaken the overall rigidity of the drill rod. Applicable scenarios: Suitable for ultra-deep hole processing with extremely high reliability requirements, as well as deep hole processing of difficult-to-machine materials (such as stainless steel, high-temperature alloys), complementing and enhancing the application scope of the BTA system. Summary selection: For precision and drilling small holes -> Select gun drill. For efficiency and drilling medium-large holes -> Select BTA. For harsh working conditions and extremely difficult tasks -> Consider spray suction drill. Deep Hole Drilling Tools,Precision Gun Drills,BTA Drilling Systems,Deep Hole Machining Solutions
