The Mafell 204290 Copying Insert is engineered specifically for Mafell BST Drilling Stations, replacing the standard insert plate at the base of the station. It enables operators to quickly and precisely drill arrays of holes for knife plate joinery, enhancing efficiency in timber framing and heavy carpentry applications.

Featuring a center diameter of 18 mm, this insert allows drill bits up to 11/16 in. in diameter (accommodating up to a 5/8 in. bolt diameter) to pass cleanly through. It requires a specialized copying insert drill bit to initially create custom wood templates, matching the bottom 24.8 mm diameter of the insert for a flawless fit and high operational repeatability.

Features & Benefits

• Precise Template Routing: Designed to fit directly into Mafell BST Drilling Stations to guide specialized bits for accurate pattern replication.

• Optimized Clearance: Center diameter of 18 mm accommodates drill bits up to 11/16 in. for up to 5/8 in. bolts.
