Most of my work lately revolves around 1/2 inch (13mm) bolts and after three bits at $20-25 each I decided I needed to sharpen, not replace. Reviews for Drill Doctor seem to be hot or cold with little in-between but I have had great luck with it and find it indispensable.</div><div id="yui_3_16_0_ym19_1_1535928995159_5068"><br></div><div id="yui_3_16_0_ym19_1_1535928995159_5068">Jon </div></div></body></html>
