3.5mm Spare Drill Bit for Countersink Bit - 5 Pack

Functions

A pack of five replacement 3.5mm drill bits for the Festool countersink-with-depth-stop bit accessory. The 3.5mm diameter is sized for the finest fixings used in cabinet and joinery work — typical applications include drawer slide fixings, small hinge installation, fine hardware mounting and detail work in thinner stock. Use these spare bits when the original drill points dull or break. The 3.5mm size is the most fragile of the countersink bit range — fine bits in hardwood will eventually snap or wander, and a fresh sharp bit is what stops a small piece of hardware fitting from holding up the assembly. Genuine Festool replacements, ground to the countersink bit specification. Cabinetmakers, joiners and kitchen installers who do fine hardware and detail fitting keep packs of 3.5mm, 4.5mm and 5mm bits in the kit so the right pilot is always available — different fixings need different pilot sizes, and substituting up or down compromises the hold.
