We have all faced the problem of never having the right diameter drill bit when we need it most. With sets of drill bits you have to buy someone else's selection of diameters and it is not cost effective to own every individual drill bit you could ever possibly require. That is why these expansive bits are such an excellent idea. Available in two sizes offering drilling diameters of 22mm - 50mm and 34mm - 80mm, these bits give you the selection of diameters without the expense of owning every individual size. Made from Japanese tool steel, these bits will drill hardwoods and softwoods with ease and the lip and spur shape of the cutting head give a straight, smooth sided, flat bottomed finish to your drill hole. The spur in the centre of the bits keeps the drill bit on course and the sharp spur scores and cuts the wood for a tear free finish. Between the lip and spur, the sharp blade scrapes away the excess wood quickly and very efficiently. The diameter is altered using a grub screw and allen key and an etched scale on the movable lip makes setting the diameter very simple. Both sizes of expansive bit offer a drill depth of up to 100mm making them an ideal choice for carpenters for drilling newel posts, hinge recesses, door locks or any other large diameter, deep hole drilling task. For use in a drill driver or bench drill, these bits have 10mm diameter shanks. Made in Japan. ©
