Comments about W.L. Fuller Drill Bit Stops:
Used for drilling spindle holes in chair seat. Attaches tightly. Checked between drilling holes and had no slippage--maintained correct depth. I'll leave attached and use other bits for through holes.
Comments about W.L. Fuller Drill Bit Stops:
Simple to adjust and has very strong grip.
Comments about W.L. Fuller Drill Bit Stops:
I use for their "stated" purpose, but I also use the 1/16 size for bits that are too small for my drill chuck (works much better than electrical tape) and the bigger ones on a "pop up" bathroom drain that keeps wanting to "pop out"
Comments about W.L. Fuller Drill Bit Stops:
Grips tight when you need it most. Very reliable.
