“Sell the hole, not the drill.” If you have ever worked in marketing or you are familiar to it, maybe you have heard of this phrase for hundreds of times. Some says that this is the essential of marketing, and other says it’s just a cliche.

Anyway, we have sold quite a large numbers of paper drills and drill bits as a manufacturer for a log time. If you look around, you may be able to find paper product with holes, such as documents ready to be bound in folders, paper bags and swing tags etc.. These are different materials and each have different diameter holes. So, it’s easy to say “hey, I need a hole on this pile of paper”, but printers would agree that it’s not always easy to get this job done properly.


Sakura Seiki, the one of the manufacturer plants for Uchida, started producing paper drills and drill bits in the 1970s’, and they know there are several different demands from the market. In general, customers want to punch “beautiful” holes “efficiently” on paper piles. When you look at drill bits, below factors need to be improved for better results .

1. Sharpness of blade : To punch holes on paper piles beautifully and easily.
2. Smoothness for both outer & inner surfaces : To prevent wastes clogging up inside and to prevent burrs and damages on papers.
3. Abradability – ease of resharpening, longer lifetime : To keep longer lifetime in good condition.

In order to improve each factor, drill bits have to be processed very accurately and there surfaces have to be as smooth as possible.

Uchida drill bits are made of special steel used for cutting tools, such as razor, scissors and knife, that has higher hardness and viscosity. The original material is a round column special steel stick. By using a CNC, both outer surface and caliber (inner surface) are lathed. As shown on the below drawings, the drill bit itself is tapered as it goes up to its base, while the caliber is tapered in opposite direction in order to prevent the wastes clogging up inside the bit. As a result, the thinnest part of the drill bit becomes as thin as 0.15mm, and this part must be evenly thin.


Inconsistency in thickness affects durability and lifetime of a drill bit. Even though this process is done by the machine, to keep certain accuracy, the machine itself needs to be highly accurate, carefully programmed and calibrated. Therefore in order to procedure truly high quality drill bits, Sakura Seiki installed a fully customized machine, specialized in processing drill bits. And to make sure that the machine is calibrated perfectly, drill bits are carefully inspected by skilled workers before delivery.


Back in the 1970s’, the quality of our drill bits were of course not as good as that for current ones. Some drill bits broke after some hundreds of strokes, but after all the trials and improvements, if used properly, our drill bits works perfectly even after 10,000 strokes. Plus, their enhanced technology invented the world smallest drill bit, which diameter is only 1.5mm. (This drill bit is used only for plastic. )

For these significant products and practices, the factory was awarded for its “Takumi” (craftsmanship) from Osaka city.

“Also, since Uchida developes and produces both paper drills and drill bits, we have tested enormous combinations of drills, drill bits and works. For example, manual stroke type drills such as VS-25 and VS-55 have to be easy enough for operator to stroke. Testing several combinations, such as various length, thickness and coating of drill bits in a wide range of drills with different rpm and stroking speed, analysing the results, improving drills and drill bits, and testing again. Since the beginning, we have kept this trial and error procedures circulating to find best practices.” Mr. Tsubakihara, the director of Sakura Seiki adds.


Based on a lot of experience and passions, Uchida is proud to take a marketshare of 75% in Domestic (Japanese) market. Yes, we sell not only the drills to punch holes, and also experiences how smoothly our drills can do it!

When we imagine to count papers, we are not talking about the substance, actually we are going to manage information (printed, packed, etc). And one biggest concern for who needs to do this procedure is: how to do it?

Of course manually is one way, but many risks involved: productivity; labour; human mistakes; stability of process (depend of period of the day is a different performance); keep clean; and so on. For progress another possibility is use a precision scale, getting the weight of substract and dividing it according to quantity of material, but still some risks are involved: large tolerance of measurement (around +/- 5%), specially for thin paper (less than 75gsm the tolerance could be higher up to 10%); productivity; labour; and fixed place to work.

The third and much more advanced workflow is to use Countron Machine. This equipment enables to count paper, carton board and some other range of substracts at high speed, high precision (over than 10 times more accurate than precision scale depending of case), automatic starting and others features you can check below.



UCHIDA has more than 40 years of know-how and around 1,000 units sold, at banks, security printers, notebooks, calendars, packaging, labels, plastic board, greeting cards, etc. We are sure that Countron Touch and Countron AT can work with accuracy and reliability.

ModelCountron TouchCountron AT
Blade and Pin
Twin-blade with suction chips
SpeedUp to 2,500 sheets/min.Up to 1,500 sheets/min.
Paper quality22 to 255 gsm80 to 400 gsm



According to the table before, we can see COUNTRON TOUCH is more dedicated to thin paper and its operation is deeply friendly through touch screen panel which you can access settings, divide quantity (insert tape), random mode (random division of quantity), check (analyze the right quantity, very useful for quality control department), printer (print resume of your job) and by PC connection the output data is loaded at Excel plan (very helpful for auditing).




On the other hand the exclusive technology of COUNTRON AT is perfect for thick or special materials thanks to twin-blade system with the same great features from TOUCH model. Futhermore these double blades do not give any damages to the corner of papers (situation very common in thick material). That’s why Countron AT has been working for finished items which would be products and sold in store.

UCHIDA Countron Touch and AT provide the most silent operation and low cost per job, because these have air pump operates by oil-free pistons, not blades as our competitors.  And also you need not to care about cost for consumables of the pump.

With UCHIDA, the future of your business must be bright!
