Usage
This Bosch auger drill bit with a 20 mm diameter and 450 mm length is designed for deep, precise drilling in softwood, hardwood, or even damp wood. Ideal for carpenters, roofers, and general construction professionals working with wood materials.
Advantages
- Precisely ground threaded centering tip ensures accurate hole positioning.
- Large rectified helical flute provides uninterrupted chip removal, even in wet wood.
- Hexagonal shank (6 sides) prevents slipping and enables secure clamping in standard 13 mm-drill chucks.
- Suits both through-holes and dowel insertions in heavy timber structures.
- Slightly higher weight (0.52 kg) due to robust construction may require firm handling during extended use.
Specifications
- Precision-ground steel body with optimized cutting geometry for efficient drilling performance.[1][3]
- High durability; suitable for frequent professional use on both dry and damp woods.[4]
- Total length: 450 mm; working length: approximately 360–385 mm; diameter: 20 mm; shank diameter: approximately 11.1 mm.[3][4]
- Differentiating features include a self-centering threaded tip and an extra-large spiral groove to facilitate fast material evacuation.[1][4]
How it works
The self-centering threaded tip pulls the auger into the wood while the large helical flute quickly removes chips. The hexagonal shank fits securely into drill chucks for stable operation across various woodworking applications.[1][2][4]
