Cap bolt counterbore to steel
On 2018-03-02 15:33:03
I could not perforate at all if I tried to process into SKS 3 material. I tried to machine only the counterbore after machining the φ 3.2 hole for small diameter with another drill without stopping, but it was found that the cutting edge was greatly damaged without cutting at all.
M3 tap on the same material (SKS 3) Other machining is done without any problem, so if it is a problem on the tool side and rubbing the torso part of the purchasing tool with a file it will easily be scraped so the material ("high vanadium highs" is stated It is considered to be a malfunction of heat treatment). In a similar drill tap reamer and the like there is no slight scratches remaining by the file but it can not be scraped by the feeling of slipping.
When reporting this to "customer inquiry window" I got a response saying "I want you to exchange it so please return it."
Since it is not easy to receive similar defective items, if you contact "I would like you to investigate the same type first", "We confirmed to the department in charge regarding the product, the possibility that customer's method of use was not suitable There is, so we can not respond to the investigation of the product. "I returned it without stopping it.
I think that it was correspondence which conviction did not go very much.
After that I also received a mail saying "The delivery date has become faster" about the product. Although I think that it is automatic transmission based on the purchase history, I feel a big doubt about the attitude of your company which does not take any correspondence despite the fear of quality defect.
Drilling for cap bolts

It is easy. However, I often use SUS 316 L, so I do not have much. I want a little more durability with coating etc.

I thought that the diameter of the shank was thicker than I thought so that I could grasp it with a drilling machine? Well it's about 10 mm, but I think that this is for M6 with hole diameter 10 mm bolt 6 mm and then for M5, M4, M3, M2.5.

It is very satisfying with the product. It is 100 points, and I'm happy that it is already two or three centimeters long. * I am requesting from here, I knew that this product was from before but there is a doubt in the photographing of the product and I bought a Fukuda Seiko (FKD) for a submerged milling cutter with a drill (for a hexagon socket head bolt) However, (Fukuda Industry is short in length), I bought a chamfered drill TPT for cap bolt (tip of a halfway shaft), I wanted consumers to understand a little more about the angle of photography and so on. The image for M8 had a look like the boundary of the cap from the drill as thin as the bowling pin so it felt like I felt like it for a flat head screwdriver but I bought it for purchasing, It was for the cap bolt, I am very sorry to purchase two similar things before,
