3.2MM Twist Drill Bit

Item No:W59007

 

1.Application in processing different materials

metal processing

Ordinary metal: It can be used to drill holes in metal plates or bars with low hardness such as mild steel, aluminum alloy, and copper, such as processing connecting holes when making small metal parts and assembling metal frames.

Thin metal plate: Drill holes in thin metal plates (such as iron sheet or aluminum sheet) to install fasteners such as screws and rivets, such as fixing furniture hardware and assembling electrical casings.

 

Wood processing: It is suitable for drilling holes in wooden boards, wooden squares and other woods. It is convenient to install wood screws, make mortise and tenon structures or threading holes. It is common in furniture making, woodcraft and other scenes.

 

Plastic processing: Drilling holes can be drilled in plastic plates, pipes and other materials to install connections, make models or through holes on equipment casings, such as assembly of plastic parts, DIY plastic products, etc.

 

Other materials: It can also be used on some non-metallic materials such as gypsum board, fiberboard, cardboard, etc., to meet different processing needs, such as drilling holes in gypsum board to install expansion screws.

 

2.Specific uses in different fields

Mechanical manufacturing: It is used to process positioning holes, connecting holes, etc. on mechanical parts. It is a common tool in the mechanical assembly process, such as the drilling of gears, brackets and other parts.

 

Electronic appliances: Drilling holes in circuit boards, electrical housings and other components to install electronic components, wires or fixing screws, such as the assembly of computer cases and household appliances.

 

Building decoration: Used to drill holes in building materials, such as drilling holes on walls (lightweight walls), door and window frames to install expansion bolts, hooks, etc., is an important step in fixing objects during the decoration process.

 

DIY Handicraft and Maintenance: Used in handmade and home maintenance scenarios, such as drilling and threading ropes when making small ornaments, re-drilling and fixing parts when repairing furniture, etc.

 

Model making: When making models (such as model aircraft and car models), it is used to drill holes in the model materials (plastic, wood, light metal) to connect or decorate parts.

 

3.Structural advantages and characteristics of twist bits

Spiral groove design: The spiral groove of the twist drill bit can discharge chips during drilling, and at the same time guide cutting fluid into the cutting area, reducing the friction between the drill bit and the material, and improving drilling efficiency and accuracy.

 

Strong versatility: 3.2MM is a common drill bit diameter and is suitable for multiple standard screws (such as M4 screws, whose screw hole diameter is about 3.2 - 3.4 mm), so it is frequently used in scenarios where such screws need to be installed.

 

Various suitable tools: It can be installed on a variety of drilling tools such as hand drills, bench drills, and impact drills (on suitable materials) to meet the operating needs of different scenarios.

 

4.precautions for use

Material adaptation: Select the appropriate rotating speed according to the hardness of the material. For example, the rotating speed should not be too high when processing metal to avoid overheating and wear of the drill; the rotating speed can be appropriately increased when processing wood.

 

Drilling positioning: Mark the hole position before drilling, and use a central punch to proofing to prevent the drill bit from slipping and deviating from the position.

 

Drill maintenance: Clean up chips after use to avoid contact with the humid environment to prevent the drill from rusting and affecting the effect of next use.
