It is very important to operate the long twist drill bit safely, which is not only conducive to ensuring personal safety, but also conducive to extending the service life of the extended twist drills. Here is what you need to do when using a long twist drill bit:

1. Check whether all parts of the drill press are normal before use;

2. The drill bit and the workpiece must be clamped and tightened. Do not hold the workpiece with your hands to avoid injuries and equipment damage caused by the rotation of the drill bit;

3. Concentrate on operation. The rocker arm and the drag plate must be locked before working. Do not hit the drill bit with a hammer or other tools when loading and unloading the drill bit, and do not use the spindle to hit the drill bit up and down. Use special keys and wrenches to load and unload. The drill chuck must not clamp the tapered shank drill bit;

4. When drilling thin plates, wooden boards need to be added. Thin plate drill bits should be sharpened and a smaller feed rate should be used. When the drill bit is about to penetrate the workpiece, the feed rate should be appropriately reduced and pressure should be applied lightly to avoid breaking the drill bit, damaging the equipment or causing accidents;

5. When the drill bit is running, it is forbidden to wipe the drill press with cotton yarn and towels and clear iron filings. After work, the drill press must be wiped clean, the power supply should be cut off, and the parts stacking and work area should be kept neat and tidy.

6. When the cutting is wrapped around the workpiece or drill bit, the drill bit should be lifted to break the cutting, and the cutting should be removed with a special tool after stopping drilling.

7. Drilling must be done within the working range of the drilling machine, and drill bits exceeding the rated diameter should not be used.

8. When changing the belt position and speed, the power supply must be cut off.

9. If any abnormal situation occurs during operation, the machine should be stopped for processing.

10. The operator must be familiar with the performance, purpose and operating precautions of the machine before operation. Novices are strictly prohibited from operating the machine alone.

The above are the details that need to be checked when using the long twist drill bit.
