Worksite power tools-introduction and use of impact drill

by:WORKSITE     2021-01-08
Impact drill: The impact structure of the impact drill has two types: dog tooth type and ball type. The ball-type impact drill is composed of movable plate, fixed plate, steel ball and so on. The movable plate is connected to the main shaft by threads and has 12 steel balls; the fixed plate is fixed on the casing with pins and has 4 steel balls. Under the action of thrust, the 12 steel balls roll along the 4 steel balls. Rotating and impacting the cemented carbide drill bit can drill holes in brittle materials such as bricks, blocks and concrete. Remove the overhead nails, make the fixed plate and follower plate roll together without impact, and can be used as a normal electric drill.

Application method:

(1) Before operation, it is necessary to check whether the power supply is consistent with the conventional rated 220V voltage on the power tool to avoid wrong connection to the 380V power supply.

(2) Before using the impact drill, please carefully check the body insulation protection, auxiliary handle and depth gauge scheduling, etc., and whether the machine has loose screws.

(3) The percussion drill must be fitted with alloy steel percussion bits or general purpose drilling bits with permissible schemes between φ6-25MM according to material requirements. Deter the use of drill bits that cross the plan.

(4) The wire of the impact electric drill should be well protected to prevent it from being damaged or cut by dragging it all over the floor, not to mention dragging the wire into oil or water to avoid oil and water corroding the wire.

(5) The power socket of the impact drill must be equipped with leakage switch equipment, and check whether the power cord is damaged. If the impact drill is used to find leakage, abnormal vibration, high heat or abnormal noise, you should stop working immediately and find an electrician in time View patching.

(6) When replacing the drill bit with the impact drill, use a special wrench and drill bit to lock the key, and never use non-special tools to hit the impact drill.

(7) When using an impact drill, keep in mind that you cannot use excessive force or tilt operations. It is necessary to tighten the appropriate drill bit and schedule the depth gauge of the impact drill beforehand. When performing straight and balanced operations, apply slowly and evenly, and do not force the use of oversized drill bits. .

(8) Familiarly master and operate functions such as forward and reverse steering control organization, tightening screws and drilling and tapping.
