This drill bit holder is made to hold drill bits of the following sizes (lenght is given as the full length of the whole bit, nut just the twisted part)

• 1mm x34mm

• 1.5mm x 40mm

• 2mm x 49mm

• 2.5mm x 57mm

• 3mm x 61mm

• 4mm x 74mm

• 5mm x 86mm

• 6mm x 93mm

• 7mm x 109mm

• 8mm x 117mm

• 9mm x 125mm

• 10mm x 133mm

• 11mm x 142mm

• 12mm x 151mm

• 13mm x 151mm

Lengthwise there is some play if you bit is a few mm longer or shorter.

The smaller holes might need some post processing with the drill bit that should go into them. For me that were the holes <=3mm

This will fit "Alpen" HSS bits.
