Drilling and driving-in operations for self-
drilling anchors. 

When self-drilling anchors (Fig 4) are used, 

the anchors can be driven in. In this case, 

use the optional accessories for self-drilling 

anchors such as the anchor adaptor. 

 

1/ When an impact anchor adaptor is 
used

,(1) attach the turning handle to the 

anchor adaptor and create a base hole by 

applying drill impact to the hole position while 

manually turning the handle. (Fig 5). In this 

case the plug is not attached to the anchor. 

(2) When a predetermined depth has been 

attained, pull out the anchor tentatively. (Fig 

6). (3) By employing a syringe, blow out the 

chips and dust. 

(4) Attach the plug to the anchor tip and drive 

in the anchor again with the electric hammer 

drill. 

(5)After driving in the anchor, use the drift 

key to separate the anchor. (see Fig 7)  

(6)By employing a manual hammer or pliers, 

snap off the tapered portion of the anchor. 

(see Fig 8) 

Caution. 

Since the snapped off tapered portion will fly 

about, pay attention to the snapping direction 

As this may cause injury. 

 

2/ When a rotation and impact anchor 
adapter is used, 

(1) attach a self-drilling anchor to the anchor 

adaptor. 

(2) Turn on the switch and drill a base hole 

with the self-drilling anchor. 

At the start of the hole-drilling slightly tilt the 

drill to determine the hole position. 

(3) After drilling clear out dust from the hole 

with the 

 

syringe, attach the plug to the 

anchor tip and drive in the anchor with a 

hand hammer. 

(4) For further operations, follow procedures 

(5) and (6) described above. When an impact 

anchor adaptor is used. 

 

When a taper shank adaptor is used 

(1)Attach a drill bit with tapered shank to the 

taper shank adaptor. 

 

 

 

 

 

 

(2) Turn on the switch, and drill a hole until it 

reaches the hole depth indicating groove. 

(see Fig 9) 

(3) After clearing out the dust and particles 

with the syringe, attach a plug to the anchor 

tip and drive in the anchor with a manual 

hammer or pliers. 

 

How to handle a core bit 

 

When a core bit is used, large caliber holes 

and blind holes can be drilled. In this case, 

use optional accessories for core bits (such 

as a center pin and core bit shank) for more 

rational operation. 

1. Mounting. 
Caution 

Prior to mounting a core bit, always 

disconnect the plug from the power supply 

receptacle.  

(1) Mount the core bit on the core bit shank 

(Fig 10) make sure you oil the screw portion 

of  the core bit shank for easy dismount. 

(2) Mount the core bit shank on the drill main 

body in the same manner as in mounting the 

drill bit and the bull point. (Fig 11)  

(3) Insert the center pin into the guide plate 

until it reaches the extremity. 

(4) Fit in the guide plate by aligning its 

concaved position with the core bit tip when 

the position of the concave is shifted by 

turning the guide plate right or left, the guide 

plate never slips off even when the drill is 

used in a downward direction. (Fig 12) 

2. Drilling holes.  

(1)

 

Insert the plug into a power supply 

receptacle.   

(2) A spring is built in the center pin. By 

straight and gentle pressing to the wall or 

floor surface, the entire surface of the core bit 

tip attains contact to start the hole drilling job.  

(3) When the hole depth reaches 

approximately 5mm, the hole position can be 

determined. Then remove the center pin and 

guide plate from the core bit and continue the 

drilling job. 

Caution

  

When removing the center pin and guide 

plate, always disconnect the plug from the 

power supply receptacle.
