SciTech-ICEE-Industrial Standard - Metric System公制标准 - 工具🛠️-Screwdriver(螺丝刀)+ 最常用的PH2/1/0三种Bits(批头)规格: 6.35mm柄的 与 4mm柄精密用(电器精电) + Oval椭圆批头常用在拆解"外国咖啡机(例如)"上

SciTech-ICEE-Industrial Standard工业标准 - 工具🛠️

Screwdriver(螺丝刀)+ 最常用的两种Bits(批头)规格: 6.35mm的家装 与 4mm精密用(电器精电)

首先 6.35mm 与 4mm ，是指Bits(批头)的"直径(边缘任意两点的最长距离)"，
而且Bits(批头)都是 "正六边形"的，直径是指正六边形的"外接圆的直径"。

• 4.0mm精密用Bits(批头)规格
  例如: 手机、笔记本电脑、数码相机、眼镜、钟表等
• 6.35mm家庭装修等常用
  例如: DesktooPC(台式电脑)、电视、冰箱、洗衣机、空调、电扇、家具什么的；

一字 + 十字 + Y型 + 星型 + …

批头的规格及序列代号

小知识点：刀头PH数值表示什么？

答：PH表示的是批头"尖端"的尖钝，数值越小表示"尖端"越尖。

最常用的三种PH2+PH1+PH0/00

PH2	PH1	PHO/PH00
家居大电器家电的常用	生活小电器的常用	精密电子电器和器械的常用

Fractional Inch Drill Bit Sizes

Imperial (fractional inch) bits are common in the UK and US.
