MODEL DM50 GUNDRILL
The DM50 Model gundrill machines have been specially designed for the North American market where accuracy, flexibility, robustness, and low cost operation are key customer requirements.
This machine is ideally suited for the Medical Industry, where small diameters and specialty materials are the norm.
The DM50 Model gundrill machine is available in single or dual spindle versions. Dual spindle Models can be configured with a common drill slide or independently operated drill slides.
The DM Series machines can be automated to meet customer productivity requirements.

Tool Steadies
Special care has been taken to minimize the “lost” length. A total of 4 tool steadies can be used, each requiring only 3/4” of additional drill stroke. When no tool steadies are utilized, the lost length can be reduced to as little as 1/2”. Gundrilling of extremely long holes, up to 200 times drill diameter, is possible.
Tailstock Options
The DM Series gundrill machine can be equipped with a variety of tailstock configurations, depending on part type, method of load and unload, and flexibility desired.
VFD motor and precision spindle with interchangeable precision collets for O.D. clamping of workpieces.
Motor and gearbox driven counter-rotation with hydraulically actuated clamping cone part clamping.
Workpiece Fixtures
Special workpiece fixturing can be designed for most any application; gundrilling of connecting rods, fuel injectors, valve bodies, injection molds, etc…
