UNIKA UR21 D-Series Dry Diamond UR21-D Short Body

Manufacturer: UNIKA
Model: UR-D (Set)/ UR-D (Body)/ UR-D (Center Pin)/ UR21 (Shank Assembly)/ UR-D (Standard Accessory)

■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

PRECAUSION ON USE

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])

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.
