How to get rid of the core
When you get rid of the core after you Wedge with Wire
finish drilling, refer to the followings.
[3]
Attach Water Collection Ring
To prevent the drainage from splashing or dripping, the water should be controlled by the use of the Water
Collection Ring (Standard Accessory).
This machine has Torsion Beam Style Fixtures for Water
Collection Ring. The Fixtures work as spring-loaded sheets to
secure the Water Collection Ring to a drilling object.
1) Pull the Beams
○
1 up, and Insert the Water Collection Ring
○
2.
2) Release the Beams on the Ring, and then connect a Hose with
the outlet for drainage
○
3.
U-Nut (M16)
Previously when a Vacuum Pad was used, the adjustment of the Fixtures to hold the Water Collection Ring was difficult
due to the raised height. To solve this problem, the each Beam has a hole for M5 Bolts and Nuts. Using the holes, the
Bolts and Nuts can be attached to allow for the increased height of the Vacuum Pad. Hex Socket Bolts (M5x25) and
Hex Nuts (M5) are available as optional items to adjust the increased height of our
Vacuum Pad.
1)
Insert Hex. Socket Bolt (M5x25) into the hole, and fasten it by U-Nut (M5).

Deep Hole Drilling
When drilling depth is deeper than the available length of the Core-Bit, refer to one of the following ways.
1)
Use Extension Bars.
Make the core cracked and pull it out.
Attach an Extension Bar.
Extension Bar for small diameter Core-Bit may not be available.
Ask a core bit manufacturer on the size of the Extension Bar.
2)
Use 3-Piece Type Core-Bit and attach Intermediate Tubes.
Lubricate on the thread portions of the Intermediate Tube with
some grease, and connect them as per following illustrations.
Regarding the size of the Intermediate Tube, ask to a core-bit
manufacturer.
NOTE
Adjust U-Nuts (M16) to the extent that the Beams can be swiveled by
hand.
