Chamfering holes
From Japan
On 2014-06-17 10:39:34
I think that it is better to think better in terms of price. Some people who have written durability but also buy again when the price is price so it will not run out. We strongly hope for resale.

Chamfering of aluminum material
From Japan
On 2014-04-30 13:21:12
I tried to chamfer the corners of the material with a milling cutter, but the cutting surface is irregular and it does not become a product. It is for chamfering holes and dish processing.

Tap lower hole chamfering, deburring (SS400 and S25C)
From Japan
On 2014-02-01 12:52:14
Used after drilling SS400 or S25C. Because it was inexpensive at a special price, it is satisfactory in terms of cost. Ideal for mild steel.

I purchased iron holes for chamfering. It was cheap so I did not expect much, but I was thinking about purchasing next time as the surface was beautifully taken. I do not know because the durability is still around 100.

Material Dracon grooves, hole chamfering
From Japan
On 2013-05-05 07:40:28
Usually we are processing aluminum material, but this time we processed duracon material. I am slightly satisfied about Bali after processing. I was concerned about the roughness of the cutting edge of the counter sink a little. I would like to pay attention when processing aluminum materials in the future.

Good cost performance. Sharp enough to be satisfied. I am concerned about sustainability.

Used for chamfering after drilling
From Japan
On 2012-08-29 17:25:18
The sharpness was reduced without using 100 spots and the deburring was supposed to be a burr tool.

Bonde 1.6 Dishes for steel plates
From Japan
On 2011-12-21 02:12:16
The use frequency is not so high, but the sharpness has fallen quickly soon. Since other brand products have been in the same usage for many years, I regret that I should have made it to a maker item. There are good ones with monotail brands, but do not purchase this counter sink again.
