We all know the importance of the hardware on the interior door, but it seems to be easy to ignore when using it. Especially when the door is being maintained, it is easy to ignore the hardware, but it is the least on the door. Part of it, we also need to care for and maintain it, in order to make its use more practical. However, because the material is mostly metal, we do not know how to maintain it is the best way, so today Xiaobian will share with you the knowledge of hardware protection.
Hardware
We maintain the interior door to make the door leaf bright and original, and the hardware is an indispensable part of the wooden door. Naturally, it is inseparable from love. Therefore, we must pay attention to the metal material when we carry out hardware maintenance. The contact with moisture will cause rust. If it is a stainless steel handle or other hardware, we can use a brightener to wipe the surface to enhance the brightness of our surface, so that our door leaf is also very beautiful overall. However, if the lock is not smooth, we can use a small amount of lead, remember not to use the oil, otherwise it will be more serious due to the adhesion of dust.
The hardware on the interior door needs our family to care for it, so be careful when using it. If it is loose, fix it in time to avoid the situation that the door leaf is falling off and a safety accident occurs. If there is a situation in the hardware of the sliding door that is caused by the adhesion of dust due to long-term sliding, we can drop one or two drops of lubricant for a period of about half a year, so that it can be well maintained. It's smooth.
In general, for the use of our interior doors and home security, we have to regularly check whether the hardware on the door is still stable and regular maintenance, so that we can make our use more comfortable.

The masonry bit is a variation of the Twist Drill Bit, the bulk of the Tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.
Masonry bits typically are used with a Hammer Drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
