Drilling to cordovan leather material
On 2015-12-10 09:43:57
Essentially requires the drilling of φ3.2, but is a steep gradient of up to trunk diameter of the above from the cutting edge of the punch is open angle with respect to the cutting edge diameter by as short as about 3mm,
Diameter When you use the φ3.2 punch becomes too large. Thus was good thing is there is a minimum of φ2 in seven set this in or going out is not be helped the hole is slightly larger open even if the drilling.
For drilling cutting edge size in the wishful, but is good there be blade length 3-5mm in almost parallel to the blade rather than the gradient.

It sharpness is not good, dull come to be, but it was early,
The sudden, because it was only necessary for the drilling of a very small number of times, it probably is enough in this.
But I think that it is not suitable for regular use,
Loss to be placed in an tool box in preparation for an emergency I do not think there is.
