UNIKA VPC Blaze Diamond Core Drill For Polyvinyl Chloride Pipe
Manufacturer: UNIKA
Model: VPC type (Straight shank)/ VPC type (Center pin)/ VPC type (Center drill)
■Diamond abrasive grit most suitable for drilling in polyvinyl chloride pipe to the cutting edge.
■Prevents drill stopping when drilling rib pipe to achieve stable operation with no burrs.
■Expands the “drilling swarf discharge hole” on the flange part to reduce weight.
■Adopts center pin system enabling simple center positioning.
◆Effective length: 110 mm
◆Applicable electric tool: Electric drill/Percussion drill(rotating mode)
*This drill cannot be used on metallic pipes such as spiral pipes and cast-iron pipes, and metallic plates.
USES
Hard polyvinyl chloride pipe•Rib pipe•FRPM pipe•PVC pipe•Marble plate•Soft siding plate
■Handling Procedure
- 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 5mm and remove the center pin.
- Lightly press the body against the drilling groove and continue operation.
■Features of brazed diamond
■Minimal amount of diamond dislodging, longer life and more grinding force in comparison with electrodeposition because the diamonds are firmly bonded.
■Less clogging and stable sharpness because diamonds are largely protruded and the space between them are deep.
■Appropriate motor
■Power consumption: 750W 8A or more
■Rotation speed: 700rpm or more
Braze diamond is only in dry conditions. Do not use water.
Dressing is unnecessary for braze diamond.
Braze diamond cannot be used for steel pipes such as spiral pipes and duct pipes.
■Matching table of sockets installed for PVC pipes
| Matching core size(mm) | Nominal diameter of pipe installed socket(mm) |
|---|---|
| 120 | 100 |
| 170 | 150 |
| 220 | 200 |
*Make sure to pay attention to the nominal diameter of socket and actual prepared hole size.
