Pilot hole to the aluminum die-cast case

Because a good tip accuracy than the drill, it is used to lower drilling put in hand drill.
Deviation during drilling also less likely to occur, we are satisfied.

Easy-to-use will more kind aligned.
Scribe was used in order ensure that holes for the position, has been used in milling machine (drilling machine).

Also How can definitely are using until now, it is good, and the drilling in the direct drill pit, a good enough is bite, is difficult drilling in the correct position.
Use under hole in the thick drill and screw taps

Weak in strength, not difficult to cut the cutting edge twist. (Tip small-diameter portion)
Who Yamawa of center drill (non co-tea packaging) is good sharpness, it can also be used in stainless steel.
Monotarou made, such as stainless steel and Katatetsu only lick the surface.
Because the cheaper of the non co-tea ring to say that cheaper than other companies, there is a need to distinguish.
It is good for non-metal, such as brass, aluminum · POM, but do not and do not think the processing material in non-ferrous.
Immediately falls sharpness.
Drilling and milling machines, turning at the time of the guide hole (pilot hole)

In the drilling of soft iron, the tip was broken merely.
Also a center drill and material of Yamawa are the same, a narrow processing material range.
Does not open only a clean hole much plastic-based, aluminum-based, such as acrylic.
The surface is only a lick in brass, bite is bad.
Meaning of titanium co tea packaging there is little.
Once received technical information from Yamawa, Inc., it is apparently not been twisted processing to the tip of the center drill is not greatly affected the sharpness.
Drill groove portion of the center drill tip diameter Φ1.0 ~ 4.0mm of Monotarou is in the straight.
(Looking at the product image, the illusion as twisted at first glance)

Or, it is probably no more than price.
There is no other manufacturer need for now.

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.
