Usage
The Notter drilling tool is designed for creating the three handle fixing holes for espagnolette locks on wooden and PVC window frames in a single operation, streamlining chassis assembly in workshop or on-site environments.
Advantages
- Performs all three required handle holes at once, ensuring precise alignment and time savings.
- Adaptable lateral drill bits fit different handle sleeve diameters for stable fixation even with slightly loosened screws.
- Compatible with standard drill chucks, allowing flexible integration into traditional workshop setups.
- A Ø25 mm bit option eliminates the need to hollow out espagnolette housings on wood frames, reducing effort and risk of error.
- The proper function depends on selecting the correct lateral bit diameter to match specific hardware brands or models.
Specifications
- Design: Steel-bodied drilling device engineered specifically for espagnolette locks in wooden and PVC window chassis; accepts custom side drill bits to match various hardware systems.[1][6]
- Sustainability: Robust construction suitable for repetitive use; no additional certification is required due to manual operation method.[1][6]
- Performance: Central hole diameter typically Ø12 mm; side hole diameters adjustable (example: Hoppe handles require ø10 mm). Delivers all three holes simultaneously with one positioning action.[6]
- Differentiating Features: Eliminates extra machining steps (such as mortising) when using specific bit sizes in wood frames. Simple chuck installation enables compatibility with most handheld power drills.[1][6]
How it works
The Notter drilling tool is clamped into a regular power drill. Once positioned at the marked location on the window frame, it bores all three necessary mounting holes—one central and two laterals—in a single pass, provided that bit sizes match the intended espagnolette lock hardware.[1][6]
