- Normal Body
- Long Body
- ■Capable of drilling reinforced concrete(cutting up to triple-reinforcement), blocks, mortar etc. without the use of water.
- ■Center pin type cuts using only rotation force, greatly reducing noise and vibration.
◆Applicable Electric Tool: Electric Drill / Percussion Drill (rotating mode)
*For porcelain ceramic tile and stone, water should be used.
Uses
REINFORCED CONCRETE•HARD EXTERIOR PANEL•Resin-based ARTIFICIAL MARBLE•MORTAR•
SOFT EXTERIOR PANEL•BLOCK•BRICK•*CERAMIC TILE
- ■Note that the cutting edge may experience wear sooner when used for concrete without the elapse of an insufficient curing period.
- ■Make sure to use the drill in the “rotation mode.” Using the drill in the percussion/impact mode may cause reakins of the cutting edge or other failures.
- ■Note that forced insertion/removal operations during drilling (the cutting edge collides against the hole bottom or hole wall) or excessive tilting of a tool may also cause failures.
- ■Make sure to use this product in a “dry” condition. Using it in a wet or a damp condition may cause not only a shorter life but also reduced operating efficiency.
■Handling Method (Dry Diamond UR-D/DL [common])
![Handling Method (Dry Diamond UR-D/DL [common])](images/ur21d_dg1.gif)
- Align the center pin with the drilling position. Hold it tight and turn on the motor switch. [Rotation mode]
- Stop the motor when the cutting edge is inserted approximately 5 mm and remove the center pin.
- Lightly press the body against the drilling groove and continue operation.
■Dressing (sharpening) operation
Perform dressing (sharpening) operation in the following cases:
- ■Where cutting quality deteriorates during drilling
- ■Where burns or discoloration is detected on the cutting edge
In dressing operation, perform normal drilling in heavy weight (hollow) blocks or GC/WA grinding wheels. Dressing operation is completed when diamond particles protrude from the cutting edge surface and streaks in the rotation direction become clear.
