About

High-quality material: the metal pilot drill is made of high-quality high-speed steel, after strict heat treatment, the hardness of the working part reaches 63-66 HRC, hard and durable, long service life. In addition, HSS centre drill is guaranteed by fully automatic sharpening process, with integral shaping, high accuracy and stable performance.
7 pilot drills: Our high-speed steel pilot drill set consists of a total of 7 parts, including 7 different sizes of pilot drill with 1.0 / 1.5 / 2.0 / 2.5 / 3.0 / 4.0 / 5.0 mm drill diameter. The different sizes can fully meet your drilling requirements.
60 degree grinding: centre drill is equipped with an angle of 60 degrees as standard. The 60 degree angle allows you to drill precise, tapered holes in metal processing, which makes positioning more accurate, reduces error and improves drilling efficiency. Metal pilot drill has a triangular shaft with non-slip design, complete grinding process, straight chuck, sharp edge, fast cut and high work efficiency.
Double head design: each pilot drill set is designed with double end, both ends can cut, cost-saving, convenient and fast. The cutting edge of the centring drill is smooth and flat, large spiral angle design, which makes the space for chip removal, which is good for removing chips and debris on the drill, prevents chip accumulation and makes drilling smoother.
Wide range of applications: pilot drill metal set is suitable for direction-dependent drilling of holes to reduce errors, and can be used for drilling holes on lathes and most electronic drills. Pilot drill is suitable for wood, cast iron, stainless steel, aluminium alloys, steel and other metal materials.
