Drill depth control set
The Big Horn 19123 provides seven split-ring stop collars that clamp around the full circumference of a drill bit so the set screw never contacts the shaft. They let woodworkers, metalworkers and DIY users set repeatable hole depths without marking the bit or risking surface damage. The collars cover bits from 1/8-Inch through 1/2-Inch and an Allen wrench is included for quick adjustment.
Check bit shank compatibility
Verify that each bit you plan to use has a smooth, round shank matching one of the listed diameters; tapered, hex or reduced-shank bits will not seat correctly in the split-ring design. Ensure your drill chuck can accommodate the collar thickness once installed so the bit still reaches the workpiece. No power-tool interface or chuck standard is specified beyond the bit sizes shown.
Low thermal and noise impact
The collars are passive metal rings that add negligible mass and generate no heat, vibration or audible noise during drilling. They draw zero electrical power and do not affect the thermal behaviour of the drill motor or battery. Normal use simply requires tightening the supplied Allen wrench to lock the collar at the desired depth.

Questions about this item
What collars and tools come in the 19123 set and do I need to buy anything else?
The 19123 set includes seven split-ring stop collars sized for 1/8-Inch, 3/16-Inch, 1/4-Inch, 5/16-Inch, 3/8-Inch, 7/16-Inch, and 1/2-Inch bits plus an allen wrench; nothing else is required.
Which collar from the 19123 set should I pick for a 3/8-Inch drill bit?
Use the collar marked 3/8-Inch — it is one of the seven sizes supplied in the 19123 set.
How does the split-ring design of the 19123 collars affect drilling depth control?
Each collar grips the full diameter of the bit without the screw touching the shaft, so the stop stays exactly where you set it for repeatable hole depth.
