Clausing 20" Drill Presses
Infinitely Variable Speed Countershaft Drive
Dial to the best RPM for the tool and material while the job is running, with a Clausing LOW/HIGH Variable Speed Drill Press.
- 150 to 2000 RPM... speeds to drill large holes, small holes to spot face, counterbore and ream.
- A flip of the switch changes from low range to high range, perfect for production applications with quick change tooling.
- Greater capacity, too, with Clausing LOW/HIGH, production rated 1-7/8" in cast iron, 7/8" in steel with optional power feed.
Handle more jobs... better, faster with a Clausing 20" LOW/HIGH drill press.
More features for superior performance:
- Heavy-duty precision head... all bearing surfaces are precision bored simultaneously for exact alignment. Eight ball bearings support the drive and spindle, lower spindle bearing has a double row to absorb both radial and thrust loads.
- 3 MT spindle... with 6-1/2" travel, 2-1/2" diameter quill and micrometer depth stop.
- 4" column with 1/2" thick wall for great rigidity, accuracy.
- Precision ground 22" x 19" oil trough table, handles large parts and fixtures.
