ESCO Mini hole saw

Drilling enables drilling work that does not generate burrs, which is impossible, eliminates waste of deburring, and improves work efficiency.
The cutting edge is excellently polished, and cobalt high-speed is used for cutting difficult-to-cut materials such as stainless steel.
Using (SKH55) material and adding ceramic coating to the surface treatment, it demonstrates cutting ability and durability more than 4 times that of Heiss.
The shank part has a total size of 6.35 mm, enabling a replaceable blade type.
The shank structure has a spring inside, and a special function is given to prevent the debris from clogging the cutter part when drilling, and continuous drilling work can be realized.
Ideal for drilling thin iron plates such as stainless steel, iron, and aluminum of 1.5 mm or less
