CS Unitec Hand-Held Core Drill, Wet, Electric, 25 Amp, 270-700-1250 RPM, Wt: 77 lbs. (motor and stand) Product Guide

This hand-held core drill is an electric, wet drilling tool designed for creating precise holes in concrete, masonry, and other hard materials. It addresses the challenge of effective core drilling while managing dust and heat through wet operation, allowing for cleaner cuts and prolonged bit life.

Typically used on construction, renovation, and industrial sites, this type of core drill is operated with a stand to stabilize the unit during drilling. The adjustable speed ranges help accommodate different core bit sizes and material hardness. Wet drilling requires a water supply to cool the bit and control slurry, which improves drilling efficiency and bit longevity.

Where This Is Used

• Onsite concrete and masonry drilling for plumbing, electrical, or mechanical penetrations
• Industrial repair and renovation projects requiring precise core holes
• Construction environments where dust control and cooling during drilling are needed

Key Details

Selection Notes

Select this core drill when working on concrete or masonry where controlled wet drilling is required to reduce heat and dust. The variable speed allows adjustment based on bit diameter and substrate hardness. Ensure the jobsite can provide a reliable water source and stable surface for the stand setup. The unit's weight and stand mean positioning for operator comfort and access to power and water are important considerations. For jobs without water access, a dry core drill would be appropriate instead.

Drill Setup Notes

Set up the drill on a firm and level surface to securely attach the stand, which stabilizes the core drill during operation. Confirm water line connections are made to provide consistent water flow at the drill bit interface to manage slurry and maintain bit cooling. Verify electrical supply meets the 25 Amp requirement for smooth motor operation. Before drilling, select the drill speed that corresponds to the bit size and material hardness for effective cutting. After use, clean slurry and debris from the drill and stand, and inspect the bit connection and water supply fittings to ensure readiness for the next job.
