SlipStop™ collars attach to drill bits with a set screw just like conventional stop collars, but that's where the similarity ends: Patented SlipStop™ collars eliminate the marring and burning that commonly occurs with conventional stop collars. Corrosion resistant stainless steel bodies are fitted with a low friction disc under a polymer boot that rotates freely when the stop contacts the work piece, so SlipStop™ collars leave a clean, unblemished surface. Six piece: 1/8", 3/16", 1/4",5/16", 3/8" and 1/2" U.S. Patent #5,795,110. USA.
Patented Slipstop™ collars won't mar or burn your workpiece.
