Frequently Asked Questions
What types of mechanisms are installed with this HW drill?
The HW mechanism drill is specifically for drilling seats for standardized European mechanisms: D35 (standard European cylinders), NL31 (31 mm latches), HL57 (handle holes at 57 mm center distance), S10 (10 mm lock cases), RE 16-2072 (rosettes and handles). Each code identifies a precise European dimensional standard — the bit must exactly match the size of the mechanism to be installed.
Is it used on wood, metal, or both?
The basic version is for wooden doors and derivatives (chipboard, MDF). For metal or armored doors, specific versions with HSS or carbide bits are required. Check the door material before purchase. Customer support available in Italian.
