RUITOOL Drill Depth Stop – Adjustable Aluminum Stop Collar Set (2 Pcs) for 5/64-3/16 and 15/64-7/16 Drills

Enhance drilling precision with a simple, reliable tool

The RUITOOL Drill Depth Stop is a lightweight aluminum collar that wraps around your drill bit to create a consistent depth limit. Designed for woodworking and a variety of materials, it stands up to everyday workshop use while protecting your bits from unintended over-penetration. This two-piece set offers practical versatility for both professionals and DIY enthusiasts seeking dependable depth control without added complexity.

Why this depth stop matters

Thoughtful design translates into real-world benefits on the job site. The aluminum alloy delivers a balance of strength and lightness, while a nylon inner ring keeps the lock secure and resistant to loosening during repetitive drilling. The two adjustable ranges let you quickly adapt to different bit sizes, so you don’t have to swap tools or re-measure constantly.

• : Aluminum alloy provides wear resistance and heat tolerance for longer service life.
• : Nylon inner ring minimizes loosening and reduces wear on the locking portion of the collar.
• Two practical sizes: Small fits 5/64"-3/16" bits (0.078"-0.18"), Large fits 15/64"-7/16" bits (0.23"-0.43").
• Fast, precise adjustments: Quick switching between settings helps you drill with consistent depth and fewer setup steps.

What you get in the package

• 2 aluminum drill stop collars in two sizes: 30-34mm x 20mm and 49-54mm x 28mm.
• Ready for a range of materials, including wood, metal, plastic, bricks, and tiles.

Real-world uses

Think of cabinet installations with evenly spaced holes, shelf peg drilling with uniform depth, or tile work where starting holes at the same depth matters. The stops help maintain consistency across multiple holes, reducing the need for rework and helping you stay on schedule.

Materials and build quality

Constructed from rigid aluminum with a nylon inner ring, this setup offers a robust, lightweight option that resists common workshop wear and heat buildup. It’s well-suited for busy shops and steady DIY workflows alike.

Tips for best results

• Test on scrap material to confirm the correct depth before working on your project piece.
• Keep the collar aligned with the bit to ensure accurate depth control during drilling.
