Feature

●High-quality materials: The tapered HSS drill bits are made of high-speed steel to reduce heat and friction cooling and automatically remove deposits from the holes during drilling. Very durable. The spiral design prevents slipping and makes drilling easier.
●Size: 1: 7 cm long, diameter (mm): 4 to 12: 4, 5, 6, 7, 8, 9, 10, 11, 12. 2: 7 cm long, diameter (mm): 4 to 20: 4, 6, 8, 10, 12, 14, 16, 18, 20. 3: 10 cm long, diameter (mm): 4 to 32: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32.
●Versatile: Step drill set used for the use of holes in a variety of materials such as steel, fine metal (thickness ≤ 5 mm), wood, fine iron, plastic, aluminium, PVC, fibreglass and other materials.
●5 modes for different needs: It is often used on sheet metal and in general construction. One drill can drill the entire range of holes required on a worktop, speeding up installation of fixtures.

Robust material

Step drill is made of high-speed steel and has a long service life. Hexagonal shaft ensures a firm clamping of the electric tool.

Spiral construction

Makes cutting faster and smoother. The step drill bit automatically removes the burrs from the hole when drilling.

Trapezoidal design

Only one drill bit is required for drilling holes of different sizes, which can meet the requirements for processing holes with different diameters.
