Drill with Confidence, Stop at the Perfect Depth.
Achieve consistent, repeatable drilling depths for professional results without damaging your work surface or scratching expensive drill bits.
Secure Lock, Zero Damage to Bits
The defining feature of this set is the internal nylon split-ring. Unlike standard all-metal collars that gouge drill shanks, the nylon acts as a protective buffer. It provides a rock-solid grip for accurate stopping power while ensuring your drill bits remain scratch-free.
Versatility for Any Project
From delicate furniture joinery to heavy-duty installations, get consistent hole depths across various materials. Ideal for repetitive drilling tasks in wood, plastic, ceramic tile, brick walls, and stainless steel. A must-have for cabinetry, doweling, and pilot holes.
Heavy-Duty Aluminum Construction
Built to outlast plastic alternatives. Crafted from premium aluminum alloy with a durable anodized finish, these collars resist wear and heat during intensive use. The knurled surface ensures a non-slip grip for quick, tool-free adjustments on the job.

Frequently Asked Questions
How do I securely attach the collar to the drill bit?
Simply unscrew the two aluminum halves slightly to release tension on the nylon ring. Slide the collar to your desired depth position on the bit shank, then firmly twist the halves back together. The compression locks the nylon ring securely against the bit.
Will this work on masonry or brad-point bits?
Yes. The collar grips the smooth shank of the drill bit. As long as your bit's shank diameter falls within the specified ranges (2-5mm or 6-11mm), it will work regardless of the bit's tip type.
Why use this over a piece of tape?
Tape wears out quickly, loses its position, and leaves sticky residue. This aluminum and nylon stop provides a precise, physical barrier that won't budge during repetitive drilling, ensuring consistent depth for every single hole.
