These are the same holders included with each of our Lee Valley router bits. Excellent for router bits, forstners, saw tooth bits, or any bit with a 1/4", 1/2", or 8mm round shank, they can be used for horizontal or vertical mounting, or anything in between.
Molded from an advanced polymer, they have flexible internal arms that hug the bit for a secure friction fit. Sold in packs of six. The 1/4" and 1/2" sockets and 8mm bit holders use #4, #8 and # 6 flat-head fixing screws (not included), respectively.
