Reamers
Reamers produce precision bores to a controlled tolerance and surface finish that drilling alone cannot achieve. The Protool range stocks over 22,000 reamers across carbide and HSS substrates, straight shank and taper shank configurations, and machine, chucking and hand reamer styles — covering the tolerances and diameters most commonly specified in engineering drawings.
Straight shank reamers are the standard choice for CNC machining centres and manual milling machines. They mount in collet chucks and drill chucks with no setup overhead. The straight shank range covers HSS and solid carbide variants in H6, H7 and H11 bore tolerances across common metric and imperial diameter ranges.
Taper shank reamers mount directly into Morse taper spindles and tailstocks, making them the preferred choice for lathe work and larger-diameter boring operations. The taper shank range extends to diameters suited to jig boring, fixture work and mould machining.
Carbide reamers outlast HSS significantly in cast iron, hardened steel and abrasive materials. HSS reamers remain the practical choice for general workshop use in mild steel, aluminium and brass — lower cost per unit and straightforward to resharpen. Both substrates are held in stock for same-day dispatch.
