We have carried out in-depth analysis on the specific conditions of the rough machining of the cylinder bore in order to obtain a better machining plan and improve the roughing efficiency of the cylinder bore.
The actual machining condition of the cylinder bore is: machining using a three-blade boring tool (see Figure 4), 75° lead angle, 0° front angle, and the blade is made of CBN material. Specific cutting parameters: cutting speed = 400m / min, feed per tooth = 0.18mm, depth of cut = 2.5mm; processing time 42.5s.

Concrete Drilling Drill Bit usually consists of Masonry Drill Bit, SDS Plus Drill Bit, SDS Max Drill Bit, etc.
Drill bits for drilling masonry, (brick and concrete) can be identified and distinguished from other drill bits by the blunt wide blade on the tip.
There are many different designs of masonry drill and you usually get what you pay for.
