How long must the centering pin be for the core drills of different lengths?
Question:
How long must the centering pin be for the core drills of different lengths?
Answer:
The length of the centering pin depends on the length of the core drill in conjunction with or without the adapter. You can find an overview under Media.
The appropriate centering pin must be selected depending on the cutting depth and overall length of the core drill.
Cutting depth 25 mm -> 82 mm long centering pin.
Cutting depth 35 mm -> 100 mm long centering pin.
Cutting depth 50 mm -> 100 mm long centering pin.
Cutting depth 75 mm -> 125 mm long centering pin.
Cutting depth 100 mm -> 158 mm long centering pin
The following applies when using an adapter:
The appropriate centering pin depends on the adapter length and the overall length of the core drill.
For core drills with a cutting depth of 25 or 35 mm in conjunction with an adapter, a 125 mm long centering pin is recommended.
For core drills with a cutting depth of 50 mm in conjunction with an adapter, a 135 mm long centering pin is recommended.
Core drills in the 12 - 65 mm diameter range usually have an inner bore of 6.4 mm.
Centering pins with a diameter of 6.35 mm are used here.
Core drills in the diameter range of (50 mm) 65 - 110 mm usually have an inner bore of 8 mm.
Centering pins with a diameter of 7.98 mm are used here.
