Pilot hole to aluminum die-cast case

Because the tip accuracy is better than the drill, it is used to drill a prepared hole into a hand drill. Dislocation at the time of drilling hardly occurs, I am satisfied.

We will arrange more types that are easy to use.
It is used to make a hole surely in the scribed position, and it is used in a milling machine (drilling machine).

Although I am still using it, it is definitely nice, if I drill directly with a drill pit, I can not drill in a precise position, because the stickiness is not so good.
Used for thick drill and screw / tap pilot holes

It is weak in strength, the cutting edge is hard to cut and not twisted. (Tip small diameter part) Yamawa's center drill (non-coating) is more sharp and can be used for stainless steel. For monotalou, stainless steel and hard iron etc. are only glancing on the surface. Even if saying that it is cheaper than other companies, non-coating is cheaper so you need to use them properly. Although it is good for nonmetal such as brass, aluminum, POM, etc., we must consider processing material even in non-ferrous metals. Sharpness falls immediately.

With a drill of soft iron, the tip sharply broke. Even if the material is the same as the center drill of Yamawa, the range of processing material is narrow. Only beautiful holes such as acrylic and plastic type · aluminum type do not open. Even with brass, you just snake the surface, the bite is bad. There is little meaning of titanium coating. When receiving technical information from Yamaha Corporation, it seems that sharpness is greatly influenced by not being threaded into the tip of the center drill. The drill groove portion of the center drill tip diameter Φ 1.0 - 4.0 mm of the monotail is straight. (If you look at the product image, it appears as though it is twisted at first glance)

Is not it more than the price? No other manufacturers are necessary at the moment.

Is it a price? I wish a little sharpness is good.

I used some of them, but there are many variations. It is mysterious because it is unstable in strength and it is the same product.

When using an electric drill in a place where the dimensions are given (2 mm drill), use it to be shifted by 0.? Mm. Drilling position is easy to determine even with a fixed drilling machine.
