   Introduction:

 

Preparation for the measurement with the Fractometer II 

 

 

ZUWACHSBOHRER 

 
Mit dem Zuwachsbohrer entnimmt man dem Holz einen Bohrkern mit dem 
Durchmesser von 5 mm. Dieser dient dann zur  Untersuchung der 
Holzfestigkeit mit dem Fractometer II. 

 

Zuwachsbohrer 

Bohrkernentnahme 

Hinweis:

  

Darauf achten, dass der Zuwachsbohrer 
in einem guten Zustand ist, damit sie 
einen intakten Bohrkern ziehen können. 

INTAKTEN BOHRKERN ZIEHEN 

 
Die Ursache einer schlechten Bohrkern- Qualität ist meistens, dass die 
Bohrerschneide 

nicht 

scharf genug und/ oder deformiert ist; die Folge 

sind zerrissene Bohrkerne oder Bohrkerne mit rauer Oberfläche. 
Die Bohrerschneide muss regelmäßig nachgeschliffen werden, damit ein 
optimaler Bohrkern entnommen werden kann. 
 
 

ZUBEHÖRMATERIAL (ZUWACHSBOHRER): 

 

-

 

Zuwachsbohrer „SUUNTO“ 300/ 400 mm lang 

-

 

Verlängerung und Ausziehhilfe 

-

 

Handkurbel für Zuwachsbohrer 

-

 

Untersuchungsstab 

-

 

Zuwachsbohrer mit Pflegeset 

-

 

Ausstoßer 

 

 

Der Ausstoßer für Bohrkerne aus dem Zuwachsbohrer 
ermöglicht ein beschädigungsfreies Ausdrücken der 
Bohrkerne aus dem Zuwachsbohrer. Durch das 
Kunststoffgehäuse, welches über den Zuwachsbohrer 
geschoben wird, ist auch eine Verletzungsgefahr beim 
Ausdrücken der Bohrkerne weitestgehend ausgeschlosse

 

 

Ejector 

 

INCREMENT BORER 

 
With the use of the increment borer one can take a core sample out of  
a wooden structure with a diameter of 5 mm. This core sample is then 
used for assessing the wood stability with the Fractometer II. 

Increment Borer 

Withdrawal of core sample 

NOTE:

  

Please make sure that increment borer is 
in good condition! 

HOW TO OBTAIN A GOOD CORE SAMPLE 

 
The cause of obtaining a bad core sample is mostly due to a dull drilling 
surface; A good indication for a bad core sample is if core sample does 
not come out in one piece or if core sample has a rough surface. 

Note:

 The drilling surface must be kept sharp at all times to ensure an 

optimal core sample. 
 
 

ACCESSORIES (INCREMENT BORER): 

 

-

 

Increment Borer „SUUNTO“ 300/ 400 mm length 

-

 

Lengthening and extract support 

-

 

Hand operated wheel for increment borer 

-

 

Examination Stick 

-

 

Increment Borer with Maintenance Kit 

-

 

Ejector 

 

 

The ejector drives out the remaining parts that stay  
in the increment borer after a core sample is obtained.  
Due to the Plastic housing of the ejector which is 
placed over the increment borer to clean the inside  
the danger of injury is minimized.
