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.
