LHC Type for rotary hammer drill | CORE DRILL | Products

■Large-bore drilling is possible even with small, lightweight hammer drills which have low striking force.
■The inclusion of spiral design for swift swarf removal.
■Center pin does not require guide plate.

◆Effective Length: 80mm

◆Matching drill: Rotary hammer drill

Concrete•Block•Brick•Mortar•Slate

■Handling Procedure

Screw the shank into the core drill body.
Insert and set the center pin while aligning it with hole on the tip end of the shank.
Attach to the lightweight hammer drill. This completes preparation.
Only the center pin is required for positioning. Once complete positioning is made by drilling to a depth of approximately 5 mm, pull out the center pin and continue drilling operation.

electrical drills appropriate for the core drill used.
Be sure to turn off the main switch of the drill and disconnect the power supply plug from the socket before attaching and detaching the core drills.
Do not touch the core drill, the shavings, or the drilled hole because they may be hot.
Wear working clothes suitable for the operation, including eye protection equipment to prevent shavings from getting into your eyes.
Prepare the working environment before starting jobs.
Read carefully the instruction manual for the electrical drill used before use.
