DME Universal Bench Top Grinding Unit When shop foot prints make it difficult to place a tool and cutter grinder at a work station or to maximize the efficiency of an operator, our Bench Top Grinder can be set inside any work station and gundrills can be easily re-ground by the operator while a part is being drilled. Or if your tool room space is being maximized this unit can be placed on any sturdy bench and our model “B” fixture can remain permanently mounted and ready to use at a moments notice without any set-up time thus increasing efficiency. The Bench Top Unit can be purchased separately or as a complete package with the grinding unit, sharpening fixture, diamond wheel and collet.

Single Flute - (Solid Carbide) Single flute solid carbide gundrills are constructed of a single piece of carbide with no braze joint at the head and tube transition. Solid carbide gundrills will yield greater tool life, more strength, rigidly, 2-3 times faster feed rates, and maximize your productivity. Due to its rigidity this tool enables much faster SFM without the whip factor therefore enabling increased feed rates. Stock diameters are available from .055” (1.397mm) to .070” (1.778mm) in lengths to 6.0” (152.4mm) Special diameters and lengths are available from .039” (1.0mm) - .1875” (4.762mm) in lengths up to 10” (254mm). Delivery is 2-3 weeks depending on carbide availability.
