When buying used machine tools, examine the cutting edge for discoloration and avoid burnt tools. Purchase from reputable suppliers who trade in used tools for new ones. Only buy long shank tools for a longer resharpening future. Smooth, discolored cutting edges are best for resharpening.

For the average home machinist, used machine tools can make up the majority of the shop’s total expense. It is imperative that only the best used machine tools are purchased, enabling you to get the most out of your tool buying budget. Suppliers of new tools often accept old off-the-shelf tools and the supplier regrinds and heat treats the old tools. This provides a good supply of used tooling that the supplier is able to sell at reduced prices to machinists who don’t have the budget or need for expensive new tooling.

There are two main areas of machine tools to look into when shopping for used items. The cutting edge and handle or shank of the tool. To get the best out of used tools, buy only tools with smooth, discolored cutting edges. Overheating a cutting edge causes noticeable loss of hardness through discoloration; these tools are often difficult to resharpen and rarely keep a sharp edge. This will force you to resharpen the tool frequently, leading to wasted time and areas of poor surface finish on your projects.
When buying used short shank machine tools, the tool has a limited amount of sharpness left. This tool will not last long and is not a good value. Buy only long shank used machine tools to ensure a long resharpening future and get more value for your money.
