Having the most robust and hard wearing mole on the market WHY NOT? The ESSIG Mole is simply a better choice with boring capabilites of over 20 metres and with less moving parts and low maintenance makes the ESSIG Mole the cheapest to service and most reliable mole out there! Why waste hard earned money on more complicated ‘flimsy’ moles, to replace after 6 months of use? When an ESSIG Mole will last well over 10 years without replacing any major parts.
