Important Notes
Drill bushes produced to standard DIN increments for internal bores:
i/d's 0,9mm to 15,0mm - 0,1mm increments e.g. 1,1 mm, 1,2mm etc.
i/d's 15,1mm and over -0,5mm increments.
Ordering drill bushes to DIN standard increments offers a cost advantage, as non-standard bores are machined to order as specials.
