Woodworking drill depth stop / drill collar — adjustable, easy-to-use depth control for precise, repeatable holes Key benefits Ensure consistent, exact hole depth to protect workpiece integrity and avoid over-drilling. Fast setup and adjustment save time on repetitive jobs and installations. Secure hold during use thanks to a non-slip surface and manual tightening — no special tools required. Versatile for multiple materials and tasks, reducing the need to change tools. What it does Acts as a depth stop (drill stop ring) that can be fixed at different positions along the drill bit to control drilling depth precisely. Adjustable inner diameter lets you set the collar to fit a range of drill bit sizes and hold firmly in place. Surface has a rutschfeste (non-slip) texture for easy manual tightening and reliable grip. Compatibility and function Designed for use with standard drill bits and compatible with a variety of drilling tasks. Manual tightening mechanism allows quick repositioning and secure locking without additional tools. Controls drilling depth accurately to protect materials and maintain consistent results across multiple holes. Practical performance Simple, practical operation: slide the collar onto the bit, adjust to the required position, tighten by hand, and drill. Built to help maintain precision in both single-hole and repeat drilling operations. Helps prevent damage from over-penetration and ensures clean, repeatable work. Typical applications Furniture installation: drill pilot holes or screw holes to exact depths to avoid splitting or damaging components. Tiling and masonry work: control depth when drilling into tiles or brick to prevent cracking or breaking. General workshop and home projects: use on wood, metal, plastic and other materials for accurate, repeatable holes. What to expect An adjustable drill stop/collar with a grippy surface that is easy to set and tighten by hand. Reliable depth control across different drilling positions and bit diameters for consistent, professional results.
