General Guide to Router Cutters30Shanks and Cutter Length1/2" shank cutters are inherently stronger which meansthey are less likely to bend or snap than the small 1/4"shank. Certain cutters can only be purchased on 1/2" shank(door set and worktop cutters). This strength allows forcutters of a larger diameter and longer length as appose tothe 1/4" shank.It is very important with both 1/4” and 1/2” shanks to feedthe cut using a mixture of plunge depth and cutter shank.This will reduce the damage to cutters and the wear on therouter bearings. Try to take more than one pass, this willallow for a better finish and reduce damage to the routerand the cutters (1/4” is more likely to bend with a heavycut). As a general guide a 1/4” (6.35mm) cuter should takeless than half of this measurement as its cut i.e. 3mm.This rule is very difficult to enforce as some cuts willcombine, using the total diameter and a side cut. So whatdo we class as 3mm? The major factor being the materialdensity which will affect how much material can safely beremoved.Modern cutters have to have a safe hold (K) line and amaximum running speed engraved upon the shank as ageneral guide. 2/3 of the cutter shank should be held inthe collet. As for speed, the noise of the router will giveyou a guide.The speed of the cutter will vary with materials but it isimportant to vary the speed feed of the operator movingthe router over the work piece or the speed in which theypass the work through the cutter set up on a table.
