Straight shank or taper shank can be, the size of the drill can also be selected: 

3，3.5,4,4.5,5,5.5,6,7,8,9,10mm,

This is a hollow drill bit drilling machine electric function, professional for tags, calendars, desk calendar, books, plastic bags, handbags and other drilling, is a printing equipment preferred.

Drilling needle usage:

1, the drill needle is used, the paper should be placed neatly, smooth or rough, not bent. When the machine moves, should pay attention to check the other parts of the machine, the coordination, lubrication. Paper placed in substandard or machine other parts of the machine, lubrication is not good, easy to plug, off the needle or lead to product failure. In addition, when drilling, has played the hole, shall not be repeated again, otherwise, can not form a circular hole is drilled, also because of skewed and blocking needle litter.

2, the use of speed:

Due to the size of the pinhole, the smaller the pinhole, the lower the pressure bar progress should be more slow.

Under the pressure of the pressure bar to maintain a uniform speed, not too fast or too slow. Too fast, the needle is too hard, easy to break the needle; too slow, it is easy to make paper products zoom.

The smaller the distance between the two holes to be drilled, the slower the speed is.

The drill work, not stop, can make drilling waste completely discharged. In addition, the need to pay attention to the use of a few hours after the drill needle, in a timely manner to replace, so as not to drill the needle in the fatigue state to continue working.

3, if the material is drilling the peritoneum, glazing paper, drilling, drilling to replace paper the difference in time not too long, can not wait to drill needle cooling after drilling: because the drill after work, film or oil will be condensed in the hole, which leads to difficult discharge. In order to prevent blocking needle, must use the offset drilling materials, to drain the waste residue in the hole, in the drill before the break, this is particularly important.

4, the total thickness of the paper to be drilled: the length of the drill and the paper material. Respectively: stack offset paper total thickness should be 80% needle length, coated paper or paper is 60%, the peritoneum or polishing paper below 40% columns: 6mm, 5CM length of drill hole distance, the total thickness of the drill offset paper should be 4cm, 3cm coated paper or paper, or paper for peritoneal the following 2cm.

5, the needle must not use any lubricant, so as not to hinder the discharge of drilling waste (can only use the candle as a lubricant). Drill when used as a noise, and then blocked, available candle eraser needle, the bit will heat at work, the candle, and along the needle upward flow, at the same time, drilling waste with candle oil discharged upstream (Note: this method only in the drill fever, hot when used) or use Diaopai soap.
