Our very popular drill/countersink/counterbore set that has been engineered to take a secure depth collar. With this feature, our set will drill, countersink or counterbore all in one operation to a high degree of accuracy. Set comprises: 3.2mm, 3.57mm, 3.96mm, 4.36mm, 4.76mm, 5.15mm and 5.55mm diameter replaceable drill bits.

Worth having.DO NOT open this pack with scissors etc, it opens like a clam shell without any tools and can be reused to hang the drills up if required. This set is well made with deep adjustable sleeves that don't twist on the drill when tightened up and are a close fit to each drill. The sizes in my set were, 5.5mm, 5mm, 4.6mm, 4.3mm, 3.9mm, 3.5mm, 3.1mm. The countersinks were accurately ground and cut clean and true, There is an extra collar that can be removed if a counterbore is required. Each drill is tapered to match the screw thread, and they are sharp. They cut quickly & cleanly, and have a ground finnish. I am well pleased with this set and would recommend it.
