No-Thrust, No-Mar Ball Bearing Set with Quick Release Hex Shank
Used to countersink holes for the heads of screws in woods, plastic and non-ferrous materials. The 2-flute integral design ensures uniform and concentric results each and every time. Carbide tips provide chip free hole edges and lasts much longer than steel countersinks.
Available in a wide variety of sizes, complete with the HSS M2 fully ground drill bit.
Warning: When drilling aluminum/non-ferrous materials, for optimal results and extended tool life use lubricant or air cooling. Make sure the material is fixed and drill is stable during drilling.
Warning: 55227 No-Mar Depth-Stop is not interchangeable with 55264 & 55626
