Dormer’s R122 spotting drills have a 120 degree point which helps with self-centering and reduces the push force needed to drill into the application material.

The precision engineered point angle provides an accurate guide to help with centering of follow-up drilling of the hole, whilst the bright finish prevents workpiece material from sticking to the cutting edges of the tool to make sure you get clean and accurate results.

R122 drills are manufactured from premium carbide for drilling a wide range of materials including steels, aluminium and stainless steels and come in a large selection of sizes to suit most drilling applications, making them a very versatile choice
