AYCWJNOHHSS NOSS Drill NOHSold0pcsThe WJ HSS NOSS Drill NOH is defined by one thing: diameters of 13~35mm on a shank reduced to a fixed 12.7mm - so an ordinary 13mm chuck, on a drill press or even a hand drill, can produce holes up to 35mm without switching to a taper-shank drill or fitting a Morse sleeve. Substrate is what separates it within the family: NOH is plain HSS rated to HRC30, in 101 variants; for stainless steel or high-tensile plate switch to the cobalt NOHC (HSS-CO, HRC40, diameter 13~25mm). If the machine has a Morse spindle and the hole must be larger still, use the taper-shank TD, which reaches 50mm. Flute length 80mm and overall length 137mm are fixed; the short rigid flute suppresses deflection and gives better hole accuracy than a long drill of the same diameter. Sizes cover diameter 13~35mm with a 12.7mm shank, in 101 variants. Made in Taiwan. How large does it go? 35mm. How is it held? A 12.7mm shank fits an ordinary 13mm three-jaw chuck. Can it drill stainless? The listed materials are carbon and alloy steel plus aluminium and copper; use NOHC for stainless. Typical applications: large holes on machines with only a small chuck, openings in plate and structural steel, and site repairs where no sleeve is available.
