MODEL DM75 / DM100 GUNDRILL
The DM75 Model gundrill machines have been specially designed for the North American market where accuracy, flexibility, robustness, and low cost are key customer requirements.
This machine is ideally suited for job shop or tool room applications where flexibility is paramount.
The DM75 Model gundrill machine is available in single or dual drill slide versions. Dual spindle models can be configured with a common drill slide or independently operated drill slides.

Tailstock Options
The DM Series gundrill machine can be equipped with a variety of tailstock configurations, depending on part type, method of load/unload, and flexibility desired.
Motor and gearbox driven counter-rotation with hydraulically actuated clamping cone part clamping.
Motor and gearbox driven counter-rotation with manual or pneumatic operated jaw chuck.
The DM75 gundrill can be configured for drilling depths to 72” or greater with traditional precision guide rails for mounting of a tailstock or with a T-slot table to utilize a variety of workpiece fixtures or a combination of both.
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.
PLC Control
Standard DM75 controls are AB Rockwell PLC and servo drives which provide simple, easy to operate control of the gundrilling machine.
Includes programmable drilling depth control and gundrilling specific program sequences for:
- Automatic operation
- Manual operation
- Tool changing position
The gundrill cycle includes:
- Progressive feed programming
- Progressive spindle speed programming for optimal adaptation of cutting parameters.
Operator Panel LCD display for:
- Operator guidance
- Process data visualization (limits vs. actual values)
- Fault diagnostics
