    I use this to extend my forstner bits while boring pepper grinders. I have found that this model has the best retention screws to hold bits in place.

    Comments about WoodRiver 3/8" x 10" Forstner Bit Extension :

    Even though the two set screws were very tight, my 1.5" forstner bit started slipping. Then I remembered reading a suggestion to slightly flatten one side of the round shaft on a grinder. This gave the set screws someplace to grab and the slipping was eliminated. Recommend to not get too agressive with large bits to avoid twisting the shaft and snapping it.

    Comments about WoodRiver 3/8" x 10" Forstner Bit Extension :

    I don't like it. It wobbles too much when drilling thru holes. I made a better one from 3/8" id steel tubing by drilling two wholes and tapping for 2 allen screws. Works really well. I have made two for half the price of this one. (1) 5" and (1) 10"
