Q:Specification of plastic expansion plug and collocation of drill bits
For domestic expansion parts, there is no size standard, so there is no way to tell you how many sizes. Plastic expansion pipe, to measure its body diameter (regardless of some special products, such as some foreign use, there will be a large part of the stay outside), due to the expansion strength of plastic parts, and the product itself is relatively small, so with the same size a bit, and not boring a bias is too large, so as not to affect the aperture.
Q:What's the difference between an impact drill or an ordinary electric drill?
The percussive drill works by rotating and impacting and can be used for natural stones or concrete.

Hammer is a kind of electric drill, mainly used in the concrete slab. Brick and stone on the hole.
Q:How big is the 6 bit that the worker says?
The default length units for machining and mechanical drawing are millimeters,
Q:Which material, gb1436 and 6542, has a good drill?
6542 is a high speed tool steel.Most of the drilling holes for high-speed processing, so the majority of small drill bit is 6542, this is the must choose.Most drilling holes are low speed processing, and the manufacturing cost is considered, so most of them do not use 6542.GB1436 "straight shank twist drill", this is a standard, is a straight shank twist drill specifications, size, not material.
Q:What drill is used in stainless iron drilling?. What color?
Drill. Ordinary sealed steel drill and outside. But when the water in the drilling bit to cool down. Because of the two bit edge part protruding is sealed steel. If a steel meet. What a high temperature. The carbon element will be between their chemical together. You can drill the drill is not moving. We often say a bit burnt. Hole is alloy. In theory it is. But not jitter. A jitter. Alloy was dropped. The bit was scrapped. In the course of the stainless steel punch. It is better to play in Taiwan. Taiwan controlled rotary speed can be adjusted.. it can reduce the friction and temperature. But to drill for long. Or water. Methods. A mineral water bottle. The bottle turned a little empty hand squeeze on it
Q:Impact drill and electric hammer drill is what is the difference?
Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, can open 6--100mm in concrete, brick, stone and other hard materials on the hole in the hammer on the opening of materials of high efficiency, but it is not a hole in the metal.
Q:What measures can be taken to prevent the bit from breaking?
I. to drill through, reduce the pressure. Slow down. Two. Drill the bit into a group
Q:What is a square hole drill and can be machined square hole?
A circular drill can only drill round holes at one time, so that it is necessary to use non-circular curves to perform the wonderful characteristics of a fixed width curve. Non circular curve of constant breadth in the simplest one is leelo triangle.
Q:How do I turn on the electric bit?
Hit the drill and press it down and pull it out. With keys or with a hammer drill.
Q:How to remove the electric clock bit
The outer part of the drill joint is provided with a plastic sleeve, and one hand pushes the plastic sleeve inward, and the other hand holds the drill bit to pull out the drill bit.
