Designed to produce dimensionally accurate holes of fine surface finish. As standard, Dormer produces a range of hand and machine operated reamers for holes up to H7 tolerance.
Reamers are produced in HSS/HSS-E/Solid Carbide.
The most common types of reamers have a left-hand spiral as the main applications involve the production of through holes, thus requiring chips to be pushed forward. For blind holes, reamers with straight flutes or right hand spirals are recommended.
Reamers can be classified into one of several types:
Solid - available in two shank types; straight (cylindrical) and morse taper
Shell - for use on arbors
Expanding - with adjustable HSS blades, generally used for light work
