1 The blade of the hole saw is made of high quality high speed steel, and its super high strength effectively extends its service life. 2 The blade of this hole cutter adopts a front and rear angled tooth design, so its cutting resistance is small and it has a strong perforation ability. 3 Thanks to its high speed steel teeth and smooth cutting edges, it can cut through wood, puff and plastic with high precision and super clean cuts. 4 The drill uses a triangular shank design because the cutting object has high hardness and the triangular shank can be installed more firmly. 5 Exquisite workmanship makes the shank and the steel blade firmly combined, becoming a perfect replacement for the old hole opener.
