APPLICATIONS
Concrete Anchor & Dowel Hole Drilling
The KT-RD12 delivers a rapid 2,800 BPM to drill clean anchor, rebar dowel, and tie-back holes in cured concrete slabs, walls, and foundations. Its lightweight 11 lb frame lets operators drill horizontally into concrete walls and overhead structures with minimal fatigue.
Masonry, Brick & Stone Fastening
Engineered for building restoration and structural renovation, this compact air drill bores precise holes into brickwork, mortar, and natural stone facades. The quick-change ball-type retainer lets masonry crews swap bits fast to keep restoration jobs moving on tight schedules.
Utility Trenching & Small-Diameter Bedrock Drilling
Contractors rely on this compact rock drill to bore shallow blast holes and split boulders during utility trenching, plumbing line prep, and electrical conduit runs. Its low 15.8 CFM air consumption allows small mobile compressors to power it easily on remote jobsites.
Confined-Space Mining & Tunnel Fastening
Designed for tight, hard-to-reach underground spaces, the drill easily installs rock bolts, utility hangers, and safety mesh in low-seam mines and crawlways. A built-in rubber dust cover protects the internal retainer parts from abrasive rock dust, grit, and moisture underground.
FREQUENTLY ASKED QUESTIONS (FAQ)
What size air compressor is required to run the KT-RD12?
The tool requires an air compressor delivering at least 15.8 CFM at 90 PSI through a standard 1/2-inch NPT air line, making it compatible with most standard portable jobsite air compressors.
What is the chuck size and retainer style on this drill?
The KT-RD12 features a 3/4" × 2" (19 × 50 mm) chuck equipped with a quick-change ball-type retainer for fast, secure bit changes without special tools.
How do the aluminum handle and rubber dust cover help on the job?
The cast aluminum handle keeps total weight down to just 11.08 lbs for easy vertical or horizontal control, while the rubber dust cover shields internal retainer components from abrasive dust and debris.
What type of oil should be used for maintenance?
Use ISO Grade 100 pneumatic tool oil daily through an inline lubricator to protect the internal cylinder and piston. Always disconnect and bleed the compressed air line before changing drill steel or servicing the tool.
