“A” tooth: straight tooth (ratched type)
It is mainly applied in finish milling and cutting. Its milling and cutting depth is shallow, about 3~5mm.
“AW” tooth: it is improved one based on “A” tooth. Tooth profile is left and right single inclined type. Its tooth function is same as that of “A” tooth, but its efficiency is higher.
“B” tooth: curved tooth (cam-generated type)
Tooth profile is bending flat tooth, mainly applied to cut deep groove. The cutting resistance is stronger than “A” tooth and the groove is deeper.
“BW” tooth: curved tooth (alternately beveled)
Tooth profile is left and right single inclined bending flat tooth, the improved one based on “B” tooth, mainly applied to cut thicker material of abnormal profile, with stronger cutting resistance, applied for general cross-cutting saw.
“C” tooth: “HI-LO” tooth (three-tooth regrinding; rough and finish tooth machining)
Its tooth profile is high and low ladder tooth profile. The difference between front and back tooth is 0.15±0.3mm. The front tooth is double-bevel, and the back tooth is flat. Its cutting efficiency is high, and can reduce cutting force when assisting in cutting saw.
“BR tooth: it is latest improved design of “B” tooth, with a fine cutting groove of about 0.4mm at the top of tooth. Its function is to re-break waste materials from cutting and sawing work pieces and to increase discharge rate, so that comparing with “BW” tooth, its cutting and sawing efficiency increases by 25%.
