1.Structural and material characteristics1.结构及材料特性

Bimetallic composite design:双金属复合设计：

Cutting part: The outer ring tooth edge is made of high-speed steel (hardness 63-67HRC), which is wear-resistant and high-temperature resistant, suitable for high-speed cutting;切削部分：外圈齿缘采用高速钢(硬度63-67HRC),耐磨耐高温,适合高速切削;

 

Base part: The inner ring and shank are made of carbon steel (such as 45 #steel), with good toughness and impact resistance to avoid fracture of the cutter head.底座部分：内圈和刀柄采用碳钢(如45 #钢),具有良好的韧性和抗冲击性,避免刀头断裂.

 

Hollow annular structure: With a positioning drill in the center, only cutting the edge of the material when drilling to reduce resistance and debris. It is suitable for processing with large holes (12-120mm).空心环形结构：中心有定位钻,钻孔时只切割材料边缘,减少阻力和杂物.适用于大孔(12-120mm)的加工.

 

2.Applicable materials and processing scenarios2.适用材料及加工场景

1)metal material processing1)金属材料加工

Conventional metal plates:传统金属板：

Drill vent holes and cable holes (such as power distribution cabinets and automobile sheet metal parts) in low-carbon steel, aluminum alloy, and copper alloy plates with a thickness of 2-8mm, for example, machining chassis cooling holes with a diameter of 50 mm.在厚度为2-8mm的低碳钢,铝合金,铜合金板上钻通气孔,电缆孔(如配电柜,汽车钣金件),如加工直径50mm的机箱冷却孔.

Open side holes in thin metal pipes (such as stainless steel water pipes, aluminum alloy profiles) for pipe connection or bracket fixation (such as drilling of drying rack crossbars).在细金属管道(如不锈钢水管,铝合金型材)上开侧孔,用于管道连接或支架固定(如烘干架横杆的钻孔).

 

Medium hardness metals: 中等硬度金属：

It can be efficiently drilled on galvanized sheet and cold-rolled steel sheet. Compared with single metal hole openers, bimetal structures are less likely to be annealed due to friction and overheating, making them suitable for batch processing (such as ventilation duct production).可在镀锌板和冷轧钢板上高效钻孔.与单金属开孔器相比,双金属结构不易因摩擦和过热而退火,适合批量加工(如通风管道生产).

 

2)Wood and plastic processing2)木材和塑料加工

Deep processing of wood: 木材深加工：

Make large-aperture round holes (such as slightly speaker mounting holes, round mortise and mortise holes) in solid wood and multilayer boards, and make desktop threading holes with a diameter of 80mm or furniture decoration holes in carpentry scenes.在实木,多层板上做大孔径圆孔(如微音箱安装孔,圆榫孔,榫孔),木工场景做直径80mm的桌面穿线孔或家具装饰孔.

When processing MDF, MDF and other plates, the sharpness of the teeth can reduce edge cracking, which is suitable for making round handle holes on cabinet door panels.在加工中密度纤维板,中密度纤维板等板材时,齿的锋利性可以减少边裂,适用于在柜门面板上制作圆柄孔.

 

Plastics and composites:

Drill large holes in PVC plates, acrylic, and ABS plates (such as light-transmitting holes in bathroom partitions and drainage holes in model boats) to meet ventilation and wiring needs, and are not easy to adhere to plastic debris.

 

3)Building and decoration materials

Lightweight panels and walls:

Drill air conditioning pipe holes (diameter 75mm) and wire sleeve holes in gypsum board and fiber cement board, and install range hoods and gas pipes during decoration;

Drill expansion bolt holes in the ceramic tiles (which need to be positioned with a glass drill bit) to fix the curtain pole or bathroom pendant (which requires low-speed operation).

 

3.typical application

1)industrial manufacturing

Mechanical and electrical equipment:

Machine heat dissipation holes (such as distribution cabinet fan installation holes), cable inlet holes (diameter of more than 60mm) on the metal chassis, or drill installation holes for fans and motor end caps.

In automobile manufacturing, sensor mounting holes and wire harness through-holes are drilled in the body steel plate to adapt to batch processing in automated production lines.

 

2)Construction and installation engineering

HVAC installation:

Drill water pipe holes (diameter 32-110mm) and ventilation pipe holes in floors and walls, such as kitchen smoke exhaust pipe through beam holes and toilet exhaust pipe holes.在地板和墙壁上打水管孔(直径32 ~ 110mm)和通风管孔,如厨房排烟管穿过横梁孔,卫生间排烟管孔等.

During steel structure construction, bolt connection holes are drilled on angle steel and channel steel for bracket assembly or equipment fixation.

 

3)DIY Home Scenes

Furniture renovation:

Add round vents to old wardrobes, drill thread holes (50mm diameter) for desks, or drill extra-large drain holes (30mm diameter) for wooden flower pots.

 

Handmade:

Make round openings for wooden storage boxes, hollow patterns on metal decorative panels, or drill feeding ports in plastic buckets (such as renovating automatic pet feeders).

 

4)Repair and modification

Car/ship maintenance:

Drill modified holes in bumpers and fuel tank caps (such as installing reversing cameras and fuel filtering devices). The bimetal structure has good vibration resistance and reduces drilling deviation.在保险杠和油箱盖上钻孔(如安装倒车摄像头和燃油过滤装置).双金属结构具有良好的抗振性,减小钻偏.

Equipment maintenance: 设备维护:

When replacing large motor bearings, drill locating holes in the end caps, or repair worn equipment mounting holes (insert bushings after reaming).更换大型电机轴承时,在端盖上钻定位孔,或修理磨损的设备安装孔(扩孔后插入衬套).

 

 

4.Performance advantages and usage points4.性能优势和使用要点

Compare advantages: 比较优势:

Fracture resistance: Carbon steel matrix enhances toughness and is more resistant to impact than all-alloy holes. It is suitable for manual drilling or uneven material scenarios;抗断裂性：碳素钢基体增强韧性,比全合金孔更耐冲击.适用于人工钻孔或材料不平整的场景;

 

Cost performance: The cost of high-speed steel gear rings is lower than that of cemented carbide and is suitable for medium-strength processing (such as unhardened steel and ordinary wood).性价比：高速钢齿圈成本低于硬质合金,适用于中等强度加工(如未硬化钢,普通木材).

 

Operation suggestions: 操作建议:

Speed control: 800-1500 RPM for metal processing, 1500-2500 RPM for wood/plastic to avoid tooth edge wear caused by high-speed idling;转速控制：金属加工800-1500转/分,木材/塑料加工1500-2500转/分,避免高速空转造成齿边磨损;

Lubrication and cooling: Apply cutting fluid (such as engine oil) when processing metal to reduce frictional heat; wood processing requires timely cleaning of debris to prevent drill sticking;润滑和冷却：加工金属时使用切削液(如机油),减少摩擦热;木材加工时需要及时清理杂物,防止钻头粘钻;

 

Positioning skills: Use a central drill or a small drill bit to drill and position first to ensure that the hole opener is vertical to avoid material damage caused by "running out of position".
