We use wood drill bits for a long time in drilling, and sometimes we need to use extra long wood drill bit . A drill bit is a tool used to drill through holes or blind holes in solid materials and ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills, and nesting drills. Although reamers and countersinks cannot drill holes in solid materials, they are customarily classified as drill bits. So what are the precautions for the maintenance of the drill?
After the drill is used, it should be checked immediately for damage, passivation and other bad conditions should be immediately polished and trimmed; the drill should be seated when stored, and it will be convenient and time-saving when it is later used and save time to find the drill again; drill through When drilling a hole, when the drill bit is about to drill through, the torque is large, so at this time, lighter pressure is required to slow the tool to avoid the drill bit from twisting due to excessive force; the center point must be drilled before drilling. The purpose is to accommodate static. Avoid the bottom of the drill bit at the static point, which can guide the drill bit to the correct drilling position; when drilling, you should make full use of cutting and pay attention to chip removal; when drilling cross holes, you should drill large diameter holes first, and then drill small diameters; When the drill bit is broken or stopped suddenly when drilling, it may be caused by too fast cutting, sharpening or rapid heat during drilling.
The maintenance and maintenance of TCT circular saw blades also have their precautions.
