Customer Reviews of Cobalt Masamune Drill（HSCO-M42）

Attached to a milling cutter for drilling after aluminum welding. Reamer was easy.

Drilling a cut surface of a laser cut 6 mm steel plate. The laser-hardened steel plate was strong enough to go down until it got dented, but the drill broke.

Durability is not well understood yet, but it seems to be no problem if it is used for breaking the nut or drilling a bolt.

It can be used fairly ordinary. It was not a feeling of saying something special. I lose the name Masamune.

The holes of stainless steel etc. are wonderfully nicely opened.

I purchased 1.1mm and 1.0mm. Although 1,0 mm was beautiful, I think that 1.1 mm is a cut piece, but many were attached. It looks like a second-hand product.

Great! A hole opens without difficulty in stainless steel material. I found something good.

I can not use one of the three bought. It was okay to check one. I have not confirmed one more

Used for rusting and breaking bolts The cutting edge of the new product is very much cut and the work progresses.

Drilling can be done easily in stainless steel. It will be more helpful if there is discount at the bulk selling.

Although it is aluminum material, there is only price and sharpness was no problem.

I used it for 2 mm thick stainless steel, but I could cleanly drill

I do not know the durability when used frequently as a professional, but amateur work is of sufficient quality.

It is used for hole processing of SUS plate, but it is low price and sharpest. Although durability is not high, it is repeating with goods with excellent cost performance.

This product is defective. It was in a state that I could not drill a hole from the beginning.

I think that it excels in sharpness and excellent in cost performance.

Masamune drill is reliable so you can always purchase with confidence. The job is good, the work goes back.

To use an extractor, I used it as a drill to open a hole in a screw. As described in the item description, you can easily puncture a hole with outstanding sharpness and screws can be removed smoothly.

I received it two days after placing an order. There is no problem especially about the product.

You can use it without problems. It is inexpensive and sharp so it is very easy to use.
