APPLICATION
Concrete Anchor & Dowel Hole Drilling
The KT-RD12K kit includes two carbide speed bits delivering 2,800 BPM to bore clean anchor and rebar dowel holes into solid concrete slabs and foundations. Its lightweight 11 lb design allows structural contractors to drill horizontally into concrete walls and overhead ceilings with minimal fatigue.
Masonry, Brick & Stone Fastening
Engineered for building renovation and structural masonry restoration, this compact air drill bores precise fastening holes into brick, mortar joints, and natural stone facades. The quick-change ball-type retainer lets crews switch between the included 1-5/8" and 1-7/8" carbide bits in seconds without stopping work.
Utility Trenching & Shallow Bedrock Drilling
Contractors rely on this pneumatic drill kit to bore blast holes and split stubborn boulders during plumbing line installations, utility trenching, and conduit runs. Its low 15.8 CFM air consumption allows standard portable compressors to run the drill easily on remote jobsites.
Confined-Space Mining & Tunnel Ground Support
Designed for tight subterranean headings, this compact drill installs rock bolts, utility hangers, and wire mesh in low-seam mines and crawlways. The built-in rubber dust cover shields internal retainer parts from abrasive rock grit, moisture, and dust during underground drilling.
