Concrete drilling work

Stability at drilling, durability, no problem. A hole opens comfortably in concrete.
Please treat the total length 160 mm (effective length 100 mm) with a diameter of 4.8 mm with Monotaro san.

During machine maintenance.

Drill concrete and set an anchor. It can be used for a long time.
Cospara is good
On 2017-04-17 09:05:27
I only use it occasionally but because the price is cheap, I purchase it because I will purchase it more than I ask and open it.
Used as a pilot hole of the product fixing plug on the concrete surface

I think that it is cheap and has durability unchanged from others. I also want to ask again next time.
Pilot hole of piping fixing saddle
On 2016-07-16 00:36:46
I always used the delta axis of Miyanaga, but since there were no 4 mm cones in variation, I tried using Bosch. I could use it without complaining here.
Drilling in a brick stone
On 2016-06-11 18:38:34
It is useful because the hole position does not shift.
Anchor pilot hole
On 2016-06-09 15:56:52
I bought it for the prepared hole of the screwed anchor. Although hammer drill used genuine as being called BOSCH, I am satisfied with both price and quality. 9.0mm and 9.5mm are saved because there is no neighborhood home center.
Saddle stop for gas piping, other for installing combustion equipment
On 2016-05-15 16:53:36
I did not spill the blade with an oscillating drill, it was also quite durable.
On 2016-03-28 18:32:24
Since it is long to the tip, it is bent only by using it once, so I can not recommend it.
Drilling in a narrow place
On 2015-12-31 14:41:43
Since it seems that the one of short type handles this only, I think that it would be good if you can choose other manufacturers as well.
Drilling of stone
On 2015-11-04 15:04:29
Because it is for concrete, it was not suitable for stone. When we opened the hole of 4.8 mm in hole diameter to 30 mm in granite, we only need to grind and weigh about 20 pieces. Head crushing or splitting When you do while cooling with water, the hard part of the bit is thin or it hits the side of the bit, and if you open in a small mouth the stone will break more easily. Hole drilling speed is good If the amount to punch holes is small, I think that COSPA is very good.

It is cheap and shipping is also early so it will be helpful
Pilot hole to RC

Drilling for concrete anchor

After all it is Bosch! It will open accurately and quickly. Why is it so different?
For plastic anchor
On 2014-11-25 18:38:28
It will last several times longer than the bits you buy at home centers etc. It also helps to reduce costs.
When burying the boundary mark of the land, it is used for squeezing the hole of the anchor rivet which fixes the boundary mark
On 2014-06-17 21:49:54
It is a very easy to use bit.
