Home improvement accessory that brings accurate, repeatable drilling depths to routine tasks, the sourcing map Drill Stop Collar Set suits small workshops and DIYers who need consistent holes. Clean, uniform results cut down on wasted material and rework. Can the collars clamp securely enough for repeated use on tougher materials?
⚡ At a Glance
- • Depth Control: Screw-type adjustable collar locks at a set position for consistent drilling depth
- • Best for: DIYers and small workshop owners who need repeatable hole depths
- • Not ideal for: Users who require variable quick-change stops for multiple bit sizes
Fits 8mm (5/16 inch) drill bits and clamps using a screw-type collar. Double-hole design increases clamping force for steadier positioning during drilling.
Consistent hole depth - with a screw-type adjustable collar
A threaded screw tightens the collar onto an 8mm shaft so the collar sits at the chosen position. The double-hole arrangement distributes the clamping force across two attachment points, reducing slippage on the bit.
Precise depth stops prevent over-drilling and ensure uniform hole depth across multiple workpieces, saving time when producing repeats or templates.
Secure clamping for tougher bits - thanks to double-hole design
Two drilled holes allow the screw to bite more firmly into the collar than single-hole collars, increasing friction against the drill shank. The stainless-steel construction resists deformation under torque.
Higher clamping force keeps twist, brad-point, and masonry bits stable during use, reducing wander and improving hole accuracy on harder materials.
Durable finish and easy setup - with anodised stainless-steel components
Anodising adds a protective surface to the stainless-steel collars to reduce wear and corrosion from repeated tightening. A supplied hex wrench enables accurate initial setting and secure fastening.
Long-lasting collars tolerate repeated workshop use and simple assembly means quicker setup between different drilling tasks.
