What to do if HIKOKI Power Tool bits can’t be attached or fall off?
- KKelsey FrancisSep 10, 2025
If HIKOKI Power Tool bits can’t be attached or fall off, it may be because the shape of the attachment portion doesn’t match. The chucking diameter of the keyless chuck is 1.5 mm to 13 mm. Use a bit that falls within the stated range. If the lock of the keyless chuck is worn, contact a HiKOKI Authorized Service Center and arrange to have the old keyless chuck replaced with a new one.
