About LEEDER Tools
LEEDER GmbH, based in Volkach, specializes in cutting tools: the company manufactures milling, drilling and threading tools made of HSS and solid carbide new, and also produces special tools such as contour cutters, O-ring cutters or multi-step step drills according to customer requirements. A key focus is the regrinding of cutting tools of all kinds – in the CNC sector, in particular milling and drilling tools made of solid carbide and HSS with shank diameters of 3 to 50 mm and tool lengths of 3xD to 70xD. The range is complemented by surface grinding (single parts to series production), manual tool grinding, saw grinding and a coating service with partner Oerlikon Balzers (including TiAlN, AlTiN, AlCrN, TiCN, TiN, DLC). The value chain is rounded off by consulting, computer-aided design drawings, tool trading and a pickup and delivery service. Customers come from the trades and industry; around 50,000 tools are ground each year.
