Feature
●M2 HSS high-speed steel: Our pilot drill set is made of high-quality M2 high-speed steel, high temperature quenching, total heat treatment, good wear resistance, corrosion resistance, low consumption and durability.
●Quick cutting: the triangular shaft design is non-slip, full grinding process, straight groove design, sharp edge, fast cutting, high work efficiency. Double head design, both ends can be used for cutting, cost-saving, convenient and fast, universal cylinder shaft, convenient disassembly and assembly
●Spiral groove: the flutes are smooth and flat with a large spiral angle design that increases the space for chip removal, helps to remove chips and deposits on the drill, prevents the accumulation of chips, reduces friction and heat and is conducive to high-speed operation to accelerate chip removal without sticking to the tool, and smoother drilling.
●High performance: the entire pilot drill set contains 7 drill bits in different sizes of 1/1.5/2/2.5/3/4/5. Drills can be used for machining centring holes and countersinks of general materials as well as for machining centre holes on the end faces of shafts and other parts. A reasonable 60 degree angle drills precise tapered holes in metal processing, making positioning more accurate, reducing errors and making drilling more efficient.
●Wide range of applications: these centring drills are used to maintain the production workpieces that need to be machined between centres or manufactured into components. It is suitable for oriented twist drills to process holes to reduce errors. It can be used with lathes and most electronic drill drivers for cutting, works for wood, steel, cast iron, stainless steel, aluminum alloys and other metal materials.
